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 tubular excretory organ, numbers of which open into the gut in insects and some other arthropods.
(oxford languages supplied the definition)
soil, rock, organic layer
Explanation:
Permeability is the ability of a layer of rock to transmit fluid such as oil or water
The factors that affect the permeability of a rock layer includes the sizes of the rock particles, the ratio of the available voids to the solid mass of the rock, the presence of trapped air and the presence of organic matter
Rocks such as gravels, and sparingly cemented sands have high permeability
The most impermeable of the options are granite and clay which for granite has large particle mass and contain no voids while clay has very fine particles packed together with little room for water
Therefore, water moves easily between layers soil, rock, organic layer
