3. what would have happened if avery had added an enzyme that digested all the nucleic acids in the mixture of heat-killed bacteria, added the mixture to harmless bacteria, and injected the mixture into mice?
the harmless bacteria would have been transformed, and the mice would have died.
the harmless bacteria would not have been transformed, and the mice would have lived.
the harmless bacteria would not have been transformed, and the mice would have died.
the harmless bacteria would have been transformed, and the mice would have lived.

The correct answer would be The harmless bacteria would not have been transformed, and the mice would have lived.

Transformation of harmless or rough strain of bacteria into a harmful or smooth strain required the transport of genetic material from smooth strain to the rough strain.

DNA (deoxyribonucleic acid) is the genetic material of most of the organisms including bacteria.

Thus, if all the the nucleic acids in the mixture of heat-killed bacteria has been digested before adding the mixture to the harmless bacteria then the harmless bacteria would not have been transformed. Consequently, the mice would have lived.

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.
