A = (v2-v1) / t --> t = (v2-v1)/A
t = (55 km/hr)/(2.5 km/hr•sec)
t = 22 sec
Organisms with small, expandable bodies, extremely large mouths, and efficient teeth are likely to be found in the bathypelagic zone
Melting ice caps and glaciers
If dominant allele = p, and recessive allele = q,
and p+q = 1, then:

So if 75% have the p, then p^2 = homozygous dominant

And if the other 25% have the q, the q^2 = homozygous recessive

Now those remaining MUST be the heterozygous, thus 2pq are those:
2pq = 2(.75)(.25) = .375
Therefore homozygous dominant are 56.3% and heterozygous are 37.5%
