In flow cytometry, what information about cells can be gained by their light scatteringprofile?A. Their sizeB. Their tissue originC. Their ageD. Their granularityE. How many nuclei they have
Answers
In flow cytometry, the information about cells that can be gained by their light scattering profile includes A. Their size and D. Their granularity.
In flow cytometry, the size of cells can be determined.(A) This can be done by measuring the light-scattering properties of cells as they pass through a laser beam. As cells pass through the laser beam, they scatter light in different directions, producing two types of signals: forward scatter (FSC) and side scatter (SSC). By analyzing the FSC and SSC signals together, flow cytometry can provide information about the size and complexity of cells in a sample. The granularity or internal complexity of cells can also be determined.(D) This is done by analyzing their light scattering profile in flow cytometry.

Earth's major climate zones can be divided into smaller regional climates.
Explain why climate zones and regional climates do not follow latitude lines exactly.
Answers
Answer:
Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.
Answer:
Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.
The Earth’s axis is tilted 23.5° to the perpendicular, meaning that the amount of sunlight that a particular latitude receives changes with the seasons. From April to September, the Northern Hemisphere is tilted toward the Sun, where it receives more energy; the Southern Hemisphere receives this additional energy between October and March, when it is tilted toward the Sun.
Arctic
From 66.5N to the North Pole is the Arctic; from 66.5S to the South Pole is the Antarctic. Places within the arctic climate zones tend to be snow- or ice-covered year-round. This is despite the fact that they tend also to be exceptionally dry, sometimes receiving as little precipitation as the world’s driest deserts. Very little snow falls on these high-latitude regions, but even less melts due to the cold temperatures and scarce sunlight. The deep ice and snow that covers these regions has been built up over hundreds, indeed thousands, of years. In these regions, the Sun hovers above the horizon at midnight in the summer and never rises at all at times during the winter.
Temperate
The temperate zone is located between the arctic and tropic zones. However, ‘temperate climate’ is something of a misnomer since most regions located within the temperate climate zones experience distinct changes across four seasons. For example, in much of eastern North America – from the Ohio Valley in the United States to the southern shores of Hudson Bay in Canada – the ‘temperate’ climate can experience both arctic and tropical weather in the same year. These climate variations increase the further an area is from an ocean or another large body of water; they diminish in areas where oceans and other large bodies of water are able to influence the climate more strongly. Temperate regions are also affected by the direction of the air flow they receive. Areas in Canada, for example, have cool Arctic air passing through, while the southern United States receives warm air from the Gulf Stream.
Tropic
The tropical belt of land and sea extending around the globe on both sides of the equator – between 23.5S and 23.5N – receives the most sunlight, but it is not necessarily the hottest since it is covered extensively by oceans that use some solar energy for evaporation. This combination of high moisture and intensive solar heating results in a persistent zone of convection (the upward movement of moist, unstable air) known as a tropical low, which often results in generous cloud formation and frequent rainfall. These factors also help moderate the temperatures within this zone.
Most areas, however, are characterized by distinct sub-climates where average temperatures, precipitation, and other factors vary noticeably. Although there are different classifications of world climates, many of these sub-climates include low latitude tropical rainforest and tropical savanna; middle latitude maritime, mediterranean, and steppe; high latitude subarctic, tundra, and polar ice cap; as well as desert and highland areas.

Do polar bears hibernate?
Answers
Although polar bears are renowned for their capacity to endure extreme cold, but they do not hibernate like other bears.
Some animals go into a profound sleep known as hibernation throughout the winter to conserve energy. An animal's body temperature dips, their heart rate slows, and their metabolism decreases during hibernation. This enables them to survive on fat reserves when food is in short supply.
Polar bears do not hibernate, nevertheless, for a number of reasons. First of all, they reside in a setting where food is constantly accessible. Polar bears do not need to accumulate fat reserves in the summer in order to survive the winter, in contrast to bears who dwell in temperate regions. All year long, they can always find food.
Second, polar bears do not need to lower their body temperature in order to conserve energy because they can endure extremely low temperatures. They are protected from the cold by a thick coating of fat and fur, and they can somewhat lower their metabolism without going into a full state of hibernation.

Answers
Answer: Two sensory neurons in your skin are directly next to each other. one propagates an action potential upon sensing heat, but the adjacent neuron does nothing. this is an example of specificity .
Sensory neurons in your skin are specialized to respond to specific stimuli. One neuron may respond to heat, while another responds to pressure or touch.
Each neuron has a specific threshold for activation and will only propagate an action potential if that threshold is reached.
In this case, the heat-sensing neuron was activated and propagated an action potential, while the adjacent neuron did not respond because it was not activated by the specific stimulus it is sensitive to.
This specificity allows for more precise perception of stimuli and helps to prevent sensory overload.

What is a isotonic solution? How does it affect a red blood cell?
What is a hypertonic solution? How does it affect a red blood cell?
What is a hypotonic solution? How does it affect a red blood cell?
Answer plz!
Answers
Answer: If you place an animal or a plant cell in a hypertonic solution, the cell shrinks
Explanation: because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ). ... A single animal cell ( like a red blood cell) placed in a hypotonic solution will fill up with water and then burst.
An isotonic solution is one wherein the solute concentration across the semipermeable membrane is the same resulting in an equilibrium state.
They do not shrink or swell in an isotonic saline solution, i.e., 0.9% w/v solution of sodium chloride
Hypertonic solution: A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
Now, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 2% w/v. The sodium chloride concentration of 2% w/v is greater than the RBC’s sodium content and hence the solution is hypertonic. This will result in shrinkage of the RBCs known as crenation
When a solution has a lower solute concentration than the solution present across the semipermeable membrane, it is known as a hypotonic solution. As a result, when a cell is placed in a hypotonic solution, an osmotic pressure gradient forces the solvent to move into the cell in order to attain equal solute
In another situation, let’s suppose RBCs are placed in a solution with a sodium chloride concentration of 0.1 % w/v. The sodium chloride concentration of 0.1% w/v is less than the RBC’s sodium content and hence hypotonic saline. This will result in swelling and eventually bursting of the RBCs which will result in the release of hemoglobin. This is known as hemolysis which is a very dangerous situation.
What is the main role of fermentation? When does it take place?
I really need this.... am desperate...
Answers
Answer:
The phrase that best describes the role of fermentation is; "it converts glucose into pyruvate and NADH".
Glycolysis is the process in which glucose is broken down. It occurs under anaerobic conditions to yield 2 ATP molecules in the process.
During fermentation, glycolysis continues in the absence of oxygen hence ATP is produced as follows; Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O. Glucose is converted into pyruvate and NADH. Pi refers to a phosphate group.

To reduce one molecule of o2 how many electrons passed through electron transport chain.
Answers
To reduce one molecule of O2 it takes 4 electrons.
Electron transfer is the last process of aerobic respiration that occurs in the inner membrane of mitochondria. In electron transport, the process of making ATP occurs which will later be used by cells to carry out activities in the body. The material for making ATP comes from NADH and FADH2 which are produced in glycolysis, oxidative decarboxylation, and the Krebs cycle. O2 acts as the final electron acceptor which will later form H2O which will be removed from the cell.
In electron transport, NADH and FADH are utilized in a series of oxidation-reduction reactions until finally used to reduce O2 to H2O. This redox reaction involving various protein complexes in the mitochondrial inner membrane is referred to as oxidative phosphorylation. The energy released in this redox process is converted into a high-energy molecule, namely ATP. To reduce one molecule of O2 it takes 4 electrons.

What is the difference between adrenergic vs cholinergic?
Answers
Adrenergic and cholinergic are terms used to describe two different types of neurotransmitters and receptors in the nervous system.
Adrenergic refers to the neurotransmitter called epinephrine (also known as adrenaline) and norepinephrine (noradrenaline), which are released by the sympathetic nervous system. These neurotransmitters bind to adrenergic receptors, which are located on many different types of cells throughout the body. Adrenergic receptors are classified into two main types: alpha-adrenergic receptors and beta-adrenergic receptors. When these receptors are stimulated by epinephrine or norepinephrine, they can cause various physiological responses, including increased heart rate, blood pressure, and respiration, as well as increased glucose release from the liver. Cholinergic, on the other hand, refers to the neurotransmitter called acetylcholine, which is released by the parasympathetic nervous system and some neurons in the central nervous system. Cholinergic neurotransmission is involved in many physiological processes, including muscle contraction, heart rate regulation, and memory formation. In summary, adrenergic and cholinergic refer to different types of neurotransmitters and their respective receptors, which play important roles in regulating various physiological processes in the body.

-Restate the question (or topic) in your own words.
-Include a few key details that support your answer.
-Try to use one or more vocabulary words in your writing.
-Write a conclusion.
-Proofread and edit your work.
Here is the article:
RED BANK, New Jersey (Achieve3000, March 22, 2021). Final exams loom and you've set up your study lair so you can bury your nose in the books and concentrate. Like a deejay seeking the exact track for the task, you thumb through your artists—Bach, Beatles, Beyoncé, Blake Shelton…your taste in music is nothing if not eclectic. So what is the perfect soundtrack for a zone of maximum mental focus and harmony? Drumroll please…
It depends.
Students from grade school to grad school love listening to tunes while hitting the books, and scientific research indicates music can have a significant impact on learning and retaining knowledge. But whether that impact helps or hinders cognitive acuity is contingent on the type of music as well as the subject being studied. In short, the best playlist for studying is highly individualized. So here's some of the science to help you cue up the best songs for the right purpose.
Music psychology—yes, it's a thing—is the study of how music influences behavior and brain function. There's little surprise that most people's brains love music and that listening to a fave song can boost and regulate mood. That's an important point when it comes to studying—research supports the idea that the more positive people feel, the better they learn and the more information they retain. In other words, music has the power to improve one's ability to concentrate and learn.
Here's where the science gets more complicated. Loud music with lyrics that make you want to lip sync interferes with the brain's "working memory." That's the neurological system that turns the text or equations you're studying into knowledge you can retrieve when needed—like during a final exam. While writing or delving into information-heavy subjects that require extensive memorization, the last thing we need are more words, ideas, or blaring beats competing for our brain's attention. For that reason, some diligent scholars swear by the soothing tones and steady mid-tempo rhythms of classical composers played at unobtrusive volumes. Favorites include Bach, Vivaldi, and Handel.
To every rule there are exceptions, though, and evidence suggests that school projects requiring brainstorming or abstract and creative thinking can benefit from music worthy of a dance party. So if you're painting for art class or coding for computer science, cranking up high-energy tunes can be a boon.
Of course, you might stick to old-school study habits, cracking the books in a quiet corner and working in silence. You can jazz up this routine with periodic "music breaks" as a reward after a quiet block of study time. But for some students—especially those stuck in noisy settings like the cafeteria, the school bus, or a room shared with a rowdy little sibling —peace and quiet is not always possible. Then, headphones providing gentle music, white noise, or nature sounds can serve as auditory shields against constant distraction.
In the end, science says that determining the best music for our study needs requires some trial and error. We should consider the subject being studied as well as such idiosyncrasies as personal learning style and individual taste. The latter is significant: Studies indicate that brain function falls flat when people are made to listen to music or sounds they don't like.
You might even devise an experiment with friends, like memorizing lists of 15 unfamiliar words while listening to music of different genres, with different tempos, at different volumes and then seeing how many you recall. You can compare your ability to activate that working memory under the influence of baroque Renaissance, pop, hip-hop, Spanish guitar, or heavy metal.
With a little investigation and a bit of science, you can reach your own conclusions. See what mix of books and beats primes your mind for optimal learning.
Answers
Answer:
Great relationship.
Explanation:
There is a great relationship between music and studying because music can increase our learning power which is very important for study. Many studies shown that music produces positive effects on a human mind and refresh the mood of the listener. Music activates both the left and right brain and the activation of both parts of the brain can increase learning power and improve memory of the student that helps in studying. Listening to music activates regions of the brain which are associated with memory, reasoning, speech, emotion, and reward.

Crossing over with linked genes produces a higher percentage of nonrecombinant offspring and a lower percentage of recombinant offspring. This is because linked genes are located close together on the same chromosome, making it less likely for them to separate during meiosis.
When crossing over occurs, the linked genes are more likely to stay together and be inherited as a nonrecombinant unit. The percentage of nonrecombinant offspring will depend on the distance between the linked genes and the frequency of crossing over.
The percentage of recombinant offspring will be lower, as crossing over between linked genes is less likely to occur. The exact percentages of nonrecombinant and recombinant offspring will vary depending on the specific genes being crossed and the genetic distance between them.

This variable is the one that affects the response of the dependent variable. Any change that occurs in the independent variable will rebound on the dependent variable and will be reflected in the experiment results.
Dependent variableThis variable is the one that completely depends on other variables, meaning that any change that occurs in other variables will cause a modification on this one. It depends on the independent variable.
When conducting an experiment, several variables might affect the results. Since the researcher is only interested in studying how the independent variable influences the dependent one, he or she must keep constant all the remaining variables so they will not influence the response.
Controlled variables -constant variable-
These are all the other variables that must be kept under control so they do not affect the results of the experiment. Their values or states must be constant in the control and experimental groups.
In the exposed example, the student is interested in knowing how talking to plants would help them to grow faster.
Independent variable ⇒ talking to plants
Dependent variable ⇒ plants' growth rate
In this case, the constant variable should be the way in which the student provide water to the plants. However, the students use two different ways to water the plants: hand watering and with sprinklers.
Since this last variable is not controlled and is not constant in the control and the experimental group, it will indeed affect the plants' growth rate.
The experiment fails in keeping constant the controlled variable.
