Which type of mutation results in a base pair within a dna sequence being replaced with a different pair?

deletion
substitution
inversion
translocation

Translocation is the type of mutation result in a base pair within a DNA sequence that is replaced with a different pair.

Substitution

Explanation:

Substitution is a type of mutation where one base pair is replaced by a different base pair.

Translocation is  a genetic change in which a piece of one chromosome breaks off and attaches to another chromosome.

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.
