Think about the dna coding sequence of a gene. if an a were swapped for a t, what kind of mutation could it cause and why? think about the dna coding sequence of a gene. if an a were swapped for a t, what kind of mutation could it cause and why? it could cause a silent, missense, or nonsense mutation because those are the types that can be caused by a nucleotide-pair substitution like this one. it could cause a nonsense mutation because the sequence would no longer be the same, so the protein would be shorter and non-functional. it could cause a frameshift nonsense or frameshift missense mutation because it would change the reading frame of the codon triplet. it could cause a silent mutation because a and t are complementary to each other so it is not really a substitution mutation.

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.  

idk im sorry.
