Longer gill rakers appear to function better for capturing open-water shallow-water prey. Which of the following types of selection is most likely to be found in a large lake (open water in the middle and shallow water around the sides) with a high density of these fish? A) directional selection B) stabilizing selection prey, while shorter gill rakers function better for capturing C) disruptive selection D) sexual selection 6 V

Explanation / Answer

Que 29 )

Ans 29 - Genetic variation arises when there is change in environmental setup. because only that would lead to demand of changed genetic makeup of an individual species. So, correct answer is (B).

Ans 30) correct answer is (C)

The explanation is given below.

Ans 31) if 46% are heterozygous the 54 % will be homozygous because according to Hardy Weinberg equation

% of Heterozygous population = 100%- the percentage of Homozygous

Ans 32) correct ans will be 0.09 because homozygous for 'a'= f(q^2) where value of q is given as 0.3 therefore, (0.3) 2 =0.09

Ans 33) correct answer to this will be (c) mutation happens to all population both prokaryotic and eukaryotic.  

Not answering further because of chegg rules.

HIt like if you understood post last two question as different set of question. All the best.
