Where do plants get the nitrogen they need?
Answer: soil
Explanation: Soil
According to 2 sources
Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N 2) to ammonia (NH 3), thereby breaking the tough triple bond of molecular nitrogen.

The correct order of respiration is:
Oxygen is absorbed in the lungs and food is absorbed in the gut, The blood transports oxygen and nutrients to individual cells, Oxygen and food pass through the cell membrane and reach mitochondria, Carbon dioxide and water pass through the cell membrane, The blood transports carbon dioxide to the lungs and water is removed from the body.
Explain the process of respiration?Respiration is the process by which living organisms produce energy from food molecules. In humans and other animals, respiration occurs in the cells of the body, particularly in the mitochondria, which are organelles responsible for producing ATP, the primary source of energy for cellular processes.
The process of respiration can be broken down into two main stages:
External respiration: This stage involves the exchange of gases (oxygen and carbon dioxide) between the body and the environment.
Internal respiration: This stage involves the use of oxygen to produce energy through cellular respiration.
In summary, respiration is the process by which living organisms produce energy from food molecules. It involves the exchange of gases between the body and the environment, and the use of oxygen to produce energy through cellular respiration.

What is stabilizing selection?
A stabilizing selection is a type of natural selection in which the selective forces/pressures such as a favor for dark-skinned against strong sunlight compared to light-skinned individuals resulted in the decrease of population's genetic variance stabilizing on a median non-extreme phenotype/trait and when average phenotypes/traits are in favor against extreme variations.
The climate changes on Earth tend to be self-amplified. For example, the Earth is
currently going through a warming trend. As the Earth's temperature rises, the ice caps
and sea ice melt, reflecting less solar radiation. This results in more absorption of the
Sun's heat, causing the Earth's temperature to rise more, and the ice to melt more. This is
an example of what type of system?
Answer:
negative feedback
Explanation:
This is an example of negative feedback system.
What do you mean by negative feeback?Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
Negative feedback (or balancing feedback) occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.

Draw and label a diagram to illustrate the principle of regulating arterioles through intrinsic vs extrinsic regulation
- Describe how chemical and physical changes determine COD (ex. metabolic changes that lead to active hyperemia, vasoactive mediators, temperature and myogenic stretch response )
Regulating Arterioles:
Arterioles are small blood vessels that regulate blood flow to different organs and tissues. They have the ability to constrict or dilate in response to changes in metabolic demand, blood pressure, and other factors. This regulation can occur through two mechanisms: intrinsic and extrinsic.What is the intrinsic vs extrinsic regulation about?Intrinsic regulation involves the arteriole itself responding to local changes in the surrounding tissue. The main factor controlling intrinsic regulation is the metabolic demand of the tissue. As tissues become more active and require more oxygen and nutrients, they release metabolic byproducts such as carbon dioxide, adenosine, and potassium ions.
Extrinsic regulation involves the nervous and endocrine systems controlling arteriolar diameter through the release of vasoactive mediators. These mediators can either cause vasoconstriction or vasodilation, depending on the physiological need. For example, the sympathetic nervous system releases norepinephrine to constrict arterioles in response to low blood pressure or stress.
Chemical and Physical Changes:
Chemical and physical changes can also determine the regulation of arterioles. In response to metabolic demand, tissues release metabolic byproducts that cause vasodilation. Vasoactive mediators such as nitric oxide and prostacyclin also promote vasodilation. Conversely, vasoconstriction can be caused by factors such as endothelin-1 and thromboxane A2.Therefore, the Physical factors such as temperature and myogenic stretch response can also affect arteriolar diameter. Cold temperatures cause vasoconstriction, while warm temperatures cause vasodilation. Myogenic stretch response is the ability of arterioles to respond to changes in blood pressure by constricting or dilating to maintain a constant flow. When blood pressure increases, the arteriole constricts to prevent an excessive flow, and when blood pressure decreases, the arteriole dilates to maintain flow.

Which of the following would be an example of an R-selected species?
An example of an R-selected species would be one that produces a large number of progeny with small size. So, the correct option is C.
R-selected species are characterized by their reproductive strategy, which focuses on producing a large number of offspring with relatively small size. These species prioritize quantity over quality when it comes to offspring production.
Option ''Large number of progeny with small size'' represents an example of an R-selected species. These species typically have a high reproductive rate and invest minimal resources in individual offspring. By producing a large number of progeny, they increase the chances of survival and successful reproduction in unpredictable or unstable environments.
In contrast, options A) Small number of progeny with small size and B) Small number of progeny with large size represent strategies more commonly associated with K-selected species. K-selected species prioritize quality over quantity, producing fewer offspring but providing them with greater parental investment and resources, resulting in larger size and higher survival rates.Option D) Large number of progeny with large size is less commonly observed in nature and does not align with the reproductive strategy of either R-selected or K-selected species.Therefore, the correct option is C.

Here's an analogy:
Think of 20 men trying to climb a steep hill in order to find their partners at the top of the hill. However, they need so much energy to get up that hill that they end up taking forever to get up there.
However, some mysterious night, a witch cut the hill in half so she wouldn't have to see them suffer anymore.
The next morning, those 20 men still struggled to get up that hill but it was less effort than they previously needed; everyone got up there and met their partners.
The reactants of a chemical reaction is just like the men. They need enough energy and other criteria in order for the reaction go undergo; but when activation energy (the hill's steepness) is high, it's going to take the reactants a long time to eventually get over that hill.
When activation energy is reduced, that hill gets smaller, meaning the reactants won't need as much energy to do what it needs to do to react, which essentially makes the rate (how fast the reaction occurs) faster.

There are three different sized aquariums in your classroom with two goldfish in each. All fish are the same size and age. Your class wants to find out if the size of the tank affects the growth of a fish.
What should be the same to make the experiment valid?
By keeping these factors constant, the experiment will be more reliable and accurate in determining whether the size of the tank affects the growth of the fish.
To make the experiment valid, there are several factors that need to be kept the same. Firstly, the amount of food given to each fish should be consistent across all three tanks. This means that the same type and amount of fish food should be given at the same time each day. This ensures that the only variable being tested is the size of the tank and not the amount of food. Secondly, the water conditions in each tank should be kept the same. The water temperature, pH level, and filtration system should be consistent to ensure that the fish are living in the same environment. Thirdly, the number of fish in each tank should be the same. Two goldfish in each tank is a good number to ensure that there is no overcrowding which can affect growth. Lastly, the location of the tanks should be the same. All tanks should receive the same amount of light exposure and be placed in an area with consistent room temperature.

If some mice have inherited a genetic mutation that causes them to have a band of white fur around the middle of their bodies, it is most likely that an ancestor of these mice also had the same genetic mutation that caused the band of white fur.
Genetic mutations are changes in DNA sequence that can be inherited by offspring from their parents. If a mutation passed down from the parent to its offspring, then next generations will also have the same mutations. The white fur band presence suggests that the mutation for this trait has been inherited through multiple generations of mice.

3. Kinases phosphorylate key residues.
4. The receptor tyrosine kinase dimerizes.
5. GTPase removes a phosphoryl group from GTP.
6. Phosphatases phosphorylate key residues.
Answer:
1. Phosphatases hydrolyze key phosphorylated residues.
Explanation:
Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.
how does research in Social Psychology help to understand why sometimes our actions (behavior) do not match our attitudes (feelings often influenced by our Beliefs
Answer:
According to psychologist Gordon Allport, social psychology uses scientific methods "to understand and explain how the thoughts, feelings, and behavior of individuals are influenced by the actual, imagined, or implied presence of other human beings." What social psychology does is that it teaches us how people's social behavior is, and how we can match certain aspects of our emotions to uncalled attitudes. For example, someone may lash out at someone they truly love when they don't mean it, solely because they are upset. Social psychology can teach us how our feelings are coordinated with our beliefs and how we can react to them appropriately.
