Answer: Antigens on the blood determine a person's blood type. Antibodies in the blood attack foreign blood not compatible with the antigens on the blood. Still stuck?
Explanation:
Blood type is determined by the presence or absence of specific antigens on the surface of red blood cells.
What is blood type?The presence or absence of certain antigens on the surface of red blood cells is described by blood type, which is a classification system.
The presence or absence of two types of antigens, A and B, determines the four major blood types: A, B, AB, and O.
The presence or absence of specific antigens on the surface of red blood cells determines blood type.
To avoid a potentially fatal reaction during a blood transfusion, it is critical to match the recipient's blood type with that of the donor.
When a person receives blood that does not match their blood type, their immune system may recognise the foreign blood cells as invaders and mount an immune response.
Therefore, blood type matching is essential to ensure the safety and effectiveness of blood transfusions.

Assume population b and population c evolve until they reach adaptive peaks and experience stabilizing selection. Both populations have the same mutation rate. Which population will have less variability in size?.
That population will have less variability in size which has slower rate of mutation or has experience less mutation.
What is mutation?A mutation refers to a change in a DNA sequence of an organism. Mutations can result from DNA copying mistakes that is made during cell division, exposure to radiation or chemicals which is called mutagens, or infection caused by viruses.
If mutation occurs slowly or not completed, it will leads to less variability in size so we can conclude that the population will have less variability in size has experience less mutation.

Which theory holds that the pitch we hear is determined by the particular location on the cochlea where the hair cells vibrate the most?.
The theory that holds the pitch we hear is determined by the particular location on the cochlea where the hair cells vibrate the most is known as the place theory of hearing.
What is the function of the Cochlea in hearing?The major function of the cochlea in hearing is that it involves the sensing of hearing and also takes part in the process of auditory transduction. It is a hollow, spiral-shaped bone present in the internal ear.
The place theory of hearing typically explains and distinguishes the difference between high-pitched sounds which majorly occupy a frequency of about 5,000 Hz.
Due to this theory only, people can able to hear sounds from different pitches because of this alteration in the frequency of their sounds that ultimately causes a sense of vibrations in the basic part of the Cochlea.
Therefore, the place theory of hearing holds that the pitch we hear is determined by the particular location on the cochlea where the hair cells vibrate the most.

How does the human impact of fertilizers impact the nitrogen cycle?.
Human impact from the use of fertilizers can significantly disrupt the nitrogen cycle, leading to imbalances in ecosystems and potentially causing environmental issues.
Fertilizers, especially synthetic nitrogen-based fertilizers, contain compounds like nitrates that are highly soluble in water.When excess fertilizer is applied to fields, gardens, or lawns, rainwater can wash away the nitrates into nearby water bodies through a process called runoff.
This runoff can lead to eutrophication, a condition where excessive nutrients, including nitrates, stimulate the overgrowth of algae in water bodies. The algae then consume oxygen as they decompose, leading to oxygen depletion and negatively impacting aquatic life.
