In human genetics, this is type of inheritance is called multiple alleles.There are more than 2 alleles in the population and there are 4 possible phenotypes for this type of inheritance. Each blood type refers to a specific antigen, most useful in blood transfusions.
Answer:
Soil is often considered an abiotic factor since it is mostly made up of small particles of rock (sand and clay) mixed with decomposed plants and animals. Plants use their roots to get water and nutrients from the soil.
Answer:
density independent
Explanation:
In Ecology, density independent factors are limiting factors that do not depend on the size of a population to affect such population. Examples of density independent limiting factors are fire outbreak, earthquake and other natural disasters.
According to this question, since density independent factors influence a population irrespective of its density, it will affect a larger population than a smaller population. For example, a fire outbreak will likely burn a large part of the population, if not all.

Answer:</h2><h3>1. four</h3>
Your heart has four separate chambers that pump blood, two on the right side and two on the left.
2. When the ventricle relaxes, the aortic valve closes <em>to prevent blood from flowing back into the ventricle</em>. When the aortic valve is not working properly, it can interfere with blood flow and cause the heart to strain to send blood to the rest of the body.
3. In medicine, a person's pulse is a pressure wave caused by the expansion of the arteries as a result of the circulation of blood pumped by the heart.
4. Capillaries are tiny vessels that branch out from arterioles to form networks around body cells.
Capillaries are very tiny blood vessels — so small that a single red blood cell can barely fit through them.
