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:
B.secrete hormones directly into the bloodstream
Answer:
The answer is "0.42"
Explanation:
Please find the complete question in the attached file.
Coastal community striped allele intensity 
Landlocked community, strip intensity allele
Its eliminated allele frequency for movement 
community And now in the sturdy vineyard optimum communities, genotype frequency of stripped characteristic (heterozygous device) in coasts
Heritable (striped) allele frecency:
(round up to the closest cent) is therefore the only frequency of coastal people.
The genome of pulling function in host population
Heterozygous feature regularly.
Therefore the inland community rate of recessed (striped), allele rate:
Following migration;
Its percentage of coastal migrants:
Coastal population Non-immigrant percentage of coastal residents:
Stripping coastal community of allele rate after immigration:
![= [q \times m]+[[q' \times(1-m)]\\\\=(0.62 \times 0.1)+(0.40 \times 0.9)\\\\=0.062+ 0.36\\\\=0.422\\\\=0.42](https://tex.z-dn.net/?f=%3D%20%5Bq%20%5Ctimes%20m%5D%2B%5B%5Bq%27%20%5Ctimes%281-m%29%5D%5C%5C%5C%5C%3D%280.62%20%5Ctimes%200.1%29%2B%280.40%20%5Ctimes%200.9%29%5C%5C%5C%5C%3D0.062%2B%200.36%5C%5C%5C%5C%3D0.422%5C%5C%5C%5C%3D0.42)
They always hunt together and in a pack so they hunt in a clumped dispersion pattern
