Ashort region of dna has the sequence 5' aagctag 3' how many hydrogen bonds form between the two strands of the double stranded dna in this region?

There are 17 hydrogen bonds in that region.

Explanation:

There are 7 pairs of bases. Four of them are between Adenine and thymine, and 3 of them are Cytosine and guanine. Adenine and Thymine form two hydrogen bonds while cytosine and guanine form three. Therefore there are in total 17 hydrogen bonds in that piece of DNA.

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.
