In a human germ cell, a replication slippage event occurs during the round of DNA replication just before meiosis. The slippage event occurred within the DNA sequence that encodes for the first exon of the KRT1 gene. The KRT1 gene encodes for the protein keratin which is found highly expressed in skin cells. The slippage event described has the potential to result in what type of mutation?

A. a somatic missense mutation
B. a somatic frameshift mutation
C. a somatic silent mutation
D. a germline missense mutation
E. a germline frameshift mutation
F. a germline silent mutation

The correct option from the given options is E which is germline frameshift mutation.

Explanation:

As per the question  meiosis occurs in germ cell  such that this mutation result in KRT1 gene mutation while slippage mutation cause change in frame by slipping some bases during replication. So this is frameshift mutation. This mutation is such that the gene is altered so a frameshift mutation.

Explanation:

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.
