A region of chromatin has recently become DNAse I hypersensitive. Which enzyme has been activated to cause this change in chromatin structure? A region of chromatin has recently become DNAse I hypersensitive. Which enzyme has been activated to cause this change in chromatin structure? phosphatase histone methyltransferase histone deacetylase histone acetylase kinase

Histone Acetylase Kinases

Explanation:

DNAse 1 hypersensitive region are regions on the chromatin that are free from nucleosomes and become accessible for transcriptional activity but they become susceptible to degradation by DNase 1. they are activated alongside histone acetylase transferases (HATs). They are usually found ahead of the promoter sequences. This HATs are enzymes that functions in histone modification by activating the tail ends of some of the histones octamers enhancing their unwounding from the DNA to make the DNA accessible to transcriptional activity.

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.
