At all times, all genes are active and code for proteins. true false

The given statement is False.

Gene ( segment of DNA that corresponds to particular protein) expression is a process by which a protein product is produced through transcription and translation of gene.

Gene expression is highly regulated process, which means that genes are only turned on whenever their protein product is required by the body ( for instance, insulin gene is turned on only when blood glucose level is high in the body).

Moreover, particular genes are activated in specific cells and other genes are turned off in order to make cell function in a specific way. Also, there are non protein coding genes in the cells that do not code for any protein.

Thus, given statement is False.

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.
