aivan3 [116]
This question is incomplete. The options are:
<span>a. be choosy about which females they mate with.
b. be indiscriminant about which females they mate with.
c. mate with as many females as possible.
d. compete to mate with choosy females.
</span>
The answer is a: be choosy about which females they mate with. 
This is because the male would in this case be investing a lot of energy in parenting its young, and would therefore adopt a strategy of mating with one or very few females. It therefore makes sense that the male would be choosy in regards to its mate.

horrorfan [7]

Answer:

(A) -> (D) -> (C) -> (B)

Explanation:

First off, given that the problem requires us to explain how life on Earth may have arisen <u>from terrestrial origins</u>, we can discard sentence (E), as impacts from meteorites would count as extraterrestrial origins.

Then it's just a matter of describing the steps by which simple compounds turned into more and more complex structures, that would in turn lead to the origin of life.

Simple inorganic compounds (such as CO₂, or NH₃) were exposed to energy, because of that they formed simple organic molecules, like carbohydrates or amino acids.

These organic molecules, in turn, would self-assemble into more complex structures, such as proteins.

Lastly, there's the phenomenon of Compartmentalization, where large organic structures became enclosed within a membrane-like structure, separating them from the 'outside' medium and thus creating primitive cells.
