As the human population grows and countries continue to develop, the demand for large fish has been steadily increasing. Unfortu

nately, the average size of the cod has decreased because the fishing nets were designed to catch the large fish and the smaller individuals could escape more easily. What is most likely happening to the genetic variation of the population of North East Arctic Cod? a. The genetic variation in the population is increasing due to selective pressure. b. The genetic variation in the population is decreasing due to selective pressure. c. The genetic variation in the population is increasing due to gene flow. d. The genetic variation in the population is decreasing due to gene flow.

Answer:

The answer is D.

Explanation:

The example given in the question is an example of gene flow which can be described as the movement of specific genes from the the gene pool population to population.

The act of catching the bigger fish and letting the smaller ones escape is changing the gene pool of the North East Arctic Cod and causing the next generations to have smaller and smaller sizes which is given as the genetic variation decrease due to gene flow.

I hope this answer helps.

A cultural complex is defined as: a several groups sharing the same trait. b a single trait spread over a geographic region. c s
Olin [163]

Answer:

d a discrete combination of traits, for example Masaai cattle herding.

Explanation:

A cultural complex consists of different cultural traits that together create a 'culture'. Thus, a cultural complex can be defined as a group of cultural traits that are functionally interrelated. A cultural trait can in turn be defined as any acquired knowledge that is learned by social interaction and interpersonal relationships. Moreover, a cultural pattern occurs when cultural traits and cultural complexes associate each other in functional roles.

Imagine that a mutation in DNA produces a protein with a slightly different amino acid sequence. how would this mutation affect
Lynna [10]

Answer:

It would most likely render the protein nonfunctional or mis-functional.

The mutation could result in three outcomes:

  1. Silent mutation, which changes the codon to the same amino acid. (AAA->AAG, both are lysine). But since the problem specified that it has a "slightly different amino acid sequence," we can assume this doesn't happen.
  2. Nonsense mutation, which changes a codon to a stop codon. This would end the chain of amino acids, making the protein potentially nonfunctional.
  3. Missense mutation, which changes a codon to another completely different codon. This can be harmful, as in sickle-cell disease, where just one amino acid, glutamic acid, is changed to valine.
