Answer:
The species that develop in aquatic environments, need to be able to have an adequate locomotion and according to the hydrostatic pressure in the water, which this pressure has the opposite direction to gravity in terrestrial life.
Explanation:
Vertebrates that have a skeleton are accustomed to gravitational forces, and this bone structure is what allows adequate locomotion to perform movements as a function of the force of earth's gravity, in water the force of gravity has no effect, since that the hydrostatic force predominates, which the direction is opposite to the gravitational forces.
Amorphous bodies, with few solid structures, not bony, make them better adapt to movements in water masses that are promoted by hydrostatic forces.
Answer:
Depending on what is shown, it can give a large scale idea or detail of many small or microphic items.
Explanation:
Answer:
D. Porous Rock
Explanation:
Fossil fuels are found underground, trapped in deposits surrounded by layers of rock.
=
Porous Rock is also known for its pockets of air, liquid or even different types of fuels.
Different phenotypes must exist in equal proportions is NOT one of the conditions that must be met for evolution by natural selection to take place. It depends on the genetic variation in the population.
<h3>Selection, evolution and genetic variation</h3>
Genetic variation is a prerequisite for evolution (and consequently natural selection) to occur.
Genetic variation represents the primary matter for which phenotypes are differentially adapted to the environmental conditions in which individuals live.
This process (natural selection) leads to the differential reproduction and survival of the fittest phenotypes.
