Bacteria provide genetic engineers with __ and __

Bacteria provide genetic engineers with _vector_ and _host_.

Vector are vehicles or carriers which are used to carry the gene of interest. They are usually plasmids which are bacterial circular genome which can replicate independently.

Hence bacterial plasmids are used for the insertion of gene of interest and its transfer to the host cell.

As plasmids is taken from the bacteria, so mostly bacteria is used as the host for the gene of interest.

the answer is c.) there is a warm front in region a and a stationary front in region b.

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.
