Answer:
c. organisms are better adapted to an environment.
Explanation:
With natural selection the parent gives of a gene that is better suited for survival in an environment.
Answer: They usually run tests too see. For example, that's why they made blood tests. They take you blood from you, and run tests to see if you have a disease.
Explanation: Hope it helps!
The correct answer is biological anthropology, or physical anthropology.
It is centered around human beings only, with respect to their common or different features that they either share or don't share with their related non-human primates and other ancestors. It deals with human evolution, the study of their behavior, reproduction, etc.
Blood supply to the spleen. The spleen's blood is supplied by the splenic artery. This artery is one of the three large arteries that branch from the celiac trunk ( also called the celiac artery ).
The celiac trunk is the first major branch coming from the abdominal aorta.
Hope this helps have a nice day
Answer:
e. is under purifying selection
Explanation:
Purifying selection removes deleterious alleles that can arise through
random mutations
.
Mutations may or may not have consequences at the level of genetic expression depending on whether those mutations are synonymous or nonsynonymous. Synonymous mutations do not generate changes in the protein to be encoded while non-synonymous ones do.
Important genes for the development of the organism - such as those involved in the neural development- are very likely to be under purifying selection, eliminating individuals with deleterious alleles since those alleles (product of non-synonymous substitutions) do not allow the individuals to survive.
