The atlantic cod (gadus callarias) is a fish which lays about 5 000 000 eggs in its lifetime. On average, only two of these eggs survive to become adult cod. This promote evolution because the environment selects the most evolved animals to survive that environment.
<h3>What is the evolutionary process?</h3>
Evolutionary processes aim, therefore, to generate greater adaptation of species in an environment. When new species of organisms are formed from gradual changes in preexisting species.
So although there are several eggs initially only those that survived the environment are able and evolved to reproduce, so the evolution of species is carried out.

Answer:
A. The fern transitioned from gametophyte generation to sporophyte generation.
Explanation:
Ferns undergo an ALTERNATION of GENERATIONS in their reproductive life cycle. That is, they alternate between an incospicuous gametophytic stage and a dominant sporophytic stage. The sporophyte produces haploid spores, which germinates into the gametophyte plant called PROTHALLUS.
The gametophyte produces gametes (male and female) which fuse together to form the diploid zygote, which eventually develops into the SPOROPHYTE plant via mitosis. In this question, the brown dots from the underside of a fern's leaves that Maria collected are the spores.
When she places them in a pot, the spores germinated into gametophyte stage, then formed sporophyte, which is the small leaves she noticed growing from the pot. From this, it can be observed that the fern is transitioning from GAMETOPHYTE generation to SPOROPHYTE generation.
This is true - psychology measures observable behaviours and used scientific methods
G. cause if you just do a ratio everything adds up.
