Answer:

Colchicine inhibits the formation of microtubules by inhibiting tubulin, a protein required for microtubule synthesis. Microtubules in the form of spindle fibers during cell division pull the DNA from the center of the mother cell into the new daughter cells. If microtubules are not formed DNA will not move into new cells. Hence new cell formation will be inhibited in the metaphase stage. Thus the correct answer is option D.

Scientists interested in the relationship among vision, foraging for food, and fitness studied three isolated populations of a s
Y_Kistochka [10]

a) Evolutionary fitness can be characterized as a person's commitment to the cutting edge's quality pool,which is chiefly founded on the aggregate or the genotype of the individual.This principally identifies with the conceptive achievement of an organic entity.  

It is fundamentally determined by the offspring that can endure and pass on the characteristics/traits.

b) Graph is already uploaded in the below attached document.  

c) The population 3 will have the most elevated frequency of heterozygotes,45% of the complete population.  

d) Since population 2 is as of now having a low number of heterozygotes, the occasion would totally eliminate them from the population or decreases their number

Explanation:

Frequency of animals in population 1 having both alleles 1 and 3

frequency of allele 1 =0.60

frequency of allele 3= 0.25

Frequency of both allele 1 and 3 would be allele 1 + allele 3 frequency x 100

= 0.60+0.25 X 100= 85%
