The sedimentation coefficient:
chubhunter [2.5K]

Answer:

option D is incorrect

Explanation:

the sedimentation coefficient is measured in Svedberg units named after the scientist Theodore Svedberg. the shape of the particle being measured in the ultracentrifuge is one of the factors that determines the sedimentation coefficient. the values are usually not additive as the sedimentation coefficient is based on the rate at which a particle sediments in an ultracentrifuge and not on the size. for example, the sedimentation coefficient of eukaryotic ribosome is 80S but is made up of the 60S large subunit and the 40S small subunit.

If a population is at Hardy-Weinberg equilibrium...
jarptica [38.1K]

Answer:

B. (i) yes; (ii)-yes

Explanation:

If a population is at Hardy-Weinberg equilibrium, allele frequencies can be calculated from the given values of genotype frequencies and genotype frequencies can be calculated if the allele frequencies are given.

For a population in Hardy-Weinberg equilibrium; p+q=1

Here, p= frequency of recessive allele and q = frequency of dominant allele.

And p2 + 2pq + q2 = 1

p2= Frequency of homozygous dominant genotype

2pq = Frequency of heterozygous dominant genotype

q2 = Frequency of homozygous recessive genotype

For example, if frequency of homozygous recessive genotype (q2) is 0.40, then, the frequency of recessive allele (q) will be = square root of 0.40= 0.63

Likewise, frequency of dominant allele (p) in this population will be = 1-q = 1-0.63 = 0.37

Why do island chains provide ideal conditions for adaptive radiation to occur?
Hoochie [10]

Answer:

The comparatively fast evolution of various species from a single common ancestor is known as adaptive radiation. It usually takes place when an organism enters a novel region and distinct traits influence its survival. The island chain offers suitable conditions for adaptive radiation to take place as when an organism of a certain species comes to an island together and get disperse all through the chain, and each of these organisms getting settle into distinct niches and exploiting various food resources in order to minimize the competition, thus, resulting into adaptive radiation.
