During DNA replication, the covalent bonding of nucleotides into a new strand of DNA is performed by .a. RNA polymerase b. DNA polymerase c. DNA d. ligase e. primase

Option B) DNA polymerase

Explanation:

During DNA replication, semi-conservative replication for instance:

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand

- the new strand contains nucleotides that are complimentary abd covalently bonded to free nucleotides present in the parent strand.

Thus, DNA polymerase is the answer

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.
