Answer:
extinction and change in species competition
The aortic valve is in the left ventricle. When the heart muscle contracts (or beats), it is pumping blood out of the heart. ... The right side collects oxygen-poor blood from the body then pumps it to the lungs where it can pick up oxygen and release carbon dioxide.
Answer:
Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.
For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.
Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).
Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.
For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1
The statement that best represents how structure relates to function is as follows: a deer's horizontal pupils help it scan the horizon for predators (option C).
<h3>What is structure in biology?</h3>
A structure, according to biology, is an arrangement or organization of parts to form an organ, system, or living thing.
The structures found in living organisms are usually function-specific. Examples of common structures in living organisms and their respective functions are as follows:
- Radula in snails - feeding
- Eyespot in Euglena- light sensing
- Claws in carnivores- for holding prey
Therefore, the statement that best represents how structure relates to function is as follows: a deer's horizontal pupils (structure) help it scan the horizon for predators (function).
