Which statement is true?
A cell that divides is called a parent cell and the two new cells are daughter cells
Two daughter cells combine to a create a parent cell
One daughter cell and one son cell are produced from each parent cell
A cell that divides is called a parent cell and the two new cells are a daughter cell and a son cell
Answer:
A cell that divides is called a parent cell and the two new cells are daughter cells
Hope this helps!
A cell that divides is called a parent cell and the two new cells are daughter cells. Thus, the correct answer is Statement 1.
When a parent cell divides into two or more daughter cells, this process is known as cell division. Cell division typically takes place as part of a lengthier cell cycle. Each parental cell produces two daughter cells, which are the means by which all cells multiply.
These freshly generated daughter cells may divide and grow, giving rise to a new cell population formed by the division and expansion of a single parental cell and its progeny.
In other words, repeated cycles of growth and division enable the formation of structures made up of millions of cells from a single cell.

In recent years, scientists and the public have raised a number of ethical and legal questions about DNA. Many of the questions involve issues of ownership and privacy of personal genetic information. Issues like these became relevant to society because which of these scientific achievements?
ANSWER: The completion of the Human Genome Project
EXPLANATION:
Human Genome Project (HGP) was completed in April, 2003. Genome varies from one individual to another.
The project involved mapping and sequencing of some people and in other to get each chromosome full sequence in individuals.
However, at the beginning of this project, concerns like ownership and privacy of personal genetic information began to spring up. People are afraid that employers may have access to their genetic information and would reject persons with health issues indicated by their unique genes and health insurance companies may also not provide insurance to people that have deficiency.
In the view of this concern, the United States in 1996 passed the Health Insurance Portability and Accountability Act (HIPAA) which guides against the non-consensual and unauthorized release of health information of individuals.

what is the experimental group in this sentence what is the effect of adding higher and lower amounts of yeast (normal is one packet) to the height of the bread?
The control group, in this case, would be the group of bread loaves to which the normal amount of yeast is added.The effect of adding higher and lower amounts of yeast to the height of the bread is likely to be seen in the volume of the bread. Yeast is a vital component of bread-making as it causes the dough to rise by producing carbon dioxide gas.
This gas then gets trapped in the gluten of the dough, causing it to bread and rise. Therefore, by adding more yeast to the dough, it is likely to rise more and result in a taller bread loaf. Conversely, by adding less yeast to the dough, it may rise less and result in a shorter bread loaf.
The impact of the amount of yeast added may also be seen in the texture of the bread. If too little yeast is added, the bread may not rise enough, resulting in a dense texture. On the other hand, if too much yeast is added, the bread may rise too much and have large air pockets, resulting in a spongy or gummy texture.

About half of the offspring plants will have purple stems, and half will have green stems. D. Most of the offspring plants will have purple stems, but some will have green stems.
Answer:
D. Most of the offspring plants will have purple stems, but some will have green stems.
Explanation:
These plants are heterozygous, which means that they have two different alleles of the same gene. One allele, the ANL one, is going to dominate over the other resulting in purple-stemmed plants, which is the color that ANL encodes for.
If we draw a Punnet Square, we can see that the majority of the offsprings will have purple stems, but some of them, the ones that have two recessive alleles, will have green stems.

To back up the scientist, when a person is more fit, their breathing will return to a normal rate faster than average, as B's rate returned faster than everyone else's, they are more fit.
Another reason the scientist could be right, is when a person is very athletic and fit, their resting heart beat is lower than an average person's heart rate. As person B has the lowest at 10, this would make them more fit.
2.
If the scientist counted wrong at all while measuring breath rates, the results could be wrong.
If each person did a different form of exercise, the results could also be wrong as different forms of exercise for each person would make the expirement inconclusive. (some exercises take more from the body than others).

Answer:
brainly me
Explanation:
When we get too hot: Sweat glands in the skin release more sweat. The sweat evaporates , removing heat energy from the skin. Blood vessels leading to the skin capillaries become wider - they dilate - allowing more blood to flow through the skin, and more heat to be lost.
When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Once on the surface, the water evaporates. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
What do you mean by sweat glands?" Sweat gland is defined by a simple tubular gland of the skin that excretes perspiration, is widely distributed in nearly all parts of the human skin, and consists typically of an epithelial tube extending spirally from a minute pore on the surface of the skin into the dermis or subcutaneous tissues where it ends in a convoluted tuft."

B. Rock #1 includes only rock strata from the Paleogene Period.
C. Rock #3 includes only rock strata from the Cretaceous Period.
D. Rock #1 includes the oldest rock strata your class examined.
Answer:
hello there
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.
Animal remains are most likely to be fossilized if their hard parts are covered by layers of sediments soon after death. With time and pressure, these sediments, such as sand, plant debris, or ash, become compressed into rock. Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal.

Why does Darwin's Theory of Natural selection disprove Lamarck's Theory of inheritance of Acquired Characteristics? Answer in a short and clear answer
Lamarck's theory of Inheritance of Acquired Characteristics proposed that an organism experiences modification that can be transmitted to its offspring. However, Darwin's Theory of Natural selection disproved the Lamarckian theory. Many biologists have tested this theory (Lamarckian theory) and the result is, more evidence is being demonstrated that the traits and behavior of organisms were the results of natural selection; hence, these changes are mainly controlled by genes.
During the process of diffusion, solute particles will generally move from an area of high solute concentration, to an area of low solute concentration. This happens because... solute particles are drawn to regions of high solvent concentration solute particles move away from regions of high solute concentration the random motion of particles suspended in a fluid results in their uniform distribution. solute particles tend to move until they are uniformly distributed within the solvent, and stop moving.
Diffusion is a passive process that does not require energy. This is why the movement of molecules occurs from an area of high concentration to an area of low concentration. In the case of solute particles, they move until they are uniformly distributed within the solvent.
During the process of diffusion, solute particles will generally move from an area of high solute concentration, to an area of low solute concentration. This happens because the random motion of particles suspended in a fluid results in their uniform distribution .
Diffusion happens due to the kinetic energy that causes a random motion of molecules. When a molecule collides with another molecule or the wall of the container it is in, the kinetic energy of the molecule is transferred to the molecules it collides with, causing them to move in different directions.
Diffusion can occur in a variety of mediums, including gases, liquids, and solids. It plays a significant role in various biological processes. For example, it helps transport nutrients and oxygen to cells and allows for the excretion of waste products. Diffusion is a passive process that does not require energy.

Paragonimus westermani mature in the lung tissues and begin to lay eggs, which hatch and release miracidia, which hatch into cercariae. The cercariae are passed into the bronchioles by the host's sputum, and they are swallowed into the gut, where they are excreted with the host's faeces. The cycle repeats itself when snails, the intermediate host of the parasite, ingest the faeces.
Paragonimus westermani is the organism that affects the lungs after the ingestion of contaminated undercooked crab. Paragonimus westermani, a flatworm, is the causative agent of Paragonimiasis, which is transmitted to humans when they ingest raw or undercooked crab or crayfish containing metacercariae.A hundred-word explanation of how Paragonimus westermani affects the lungs after ingestion of undercooked crab is given below:Paragonimus westermani larvae, which are present in the undercooked crab or crayfish, hatch and mature into adult worms after ingestion by humans. The adult worm then penetrates the wall of the small intestine, enters the peritoneal cavity, and enters the lung tissue via the diaphragm and the pleura. Paragonimus westermani mature in the lung tissues and begin to lay eggs, which hatch and release miracidia, which hatch into cercariae. The cercariae are passed into the bronchioles by the host's sputum, and they are swallowed into the gut, where they are excreted with the host's faeces.

how to tell how adiabatically your column is operating at
To determine how adiabatically your column is operating, you will need to calculate the adiabatic efficiency of the column.
The adiabatic efficiency of a column is defined as the ratio of the actual change in enthalpy to the maximum possible change in enthalpy. The equation for calculating adiabatic efficiency is:
Adiabatic efficiency = (Actual change in enthalpy) / (Maximum possible change in enthalpy)
To calculate the actual change in enthalpy, you will need to know the inlet and outlet temperatures of the column, as well as the heat capacity of the fluid. The equation for calculating the actual change in enthalpy is:
Actual change in enthalpy = (Heat capacity) x (Outlet temperature - Inlet temperature)
To calculate the maximum possible change in enthalpy, you will need to know the inlet temperature of the column, as well as the adiabatic flame temperature of the fluid. The equation for calculating the maximum possible change in enthalpy is:
Maximum possible change in enthalpy = (Heat capacity) x (Adiabatic flame temperature - Inlet temperature)
Once you have calculated the actual change in enthalpy and the maximum possible change in enthalpy, you can plug these values into the equation for adiabatic efficiency to determine how adiabatically your column is operating. The closer the adiabatic efficiency is to 1, the more adiabatically the column is operating.
