A) weapons for an evolutionary arms race w/ disease causing organisms
Answer:1.Selection of the dark-colored moths over light-colored moths after industrial evolution is an example of directional selection while selection of alpha males and “sneaking” males over intermediate males in a lobster population is an example of disruptive selection.
2.organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur.

i really hopes this helps
Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.
Well as a population grows, resources become scarcer to accommodate for the growing population. So either the Minnows leave to different areas or they fight for the resources. I have finished BIO a few months ago(maybe more idk) so if I’m incorrect I do apologize, but good luck anyway. :)
In order to grow your cells need to expand and divide in order for your body to grow.
