The paired cartilages that articulate with the superior border of the cricoid cartilage are the cartilages.

The correct answer is "arytenoid".

Explanation:

The paired cartilages that articulate with the superior border of the cricoid cartilage are the arytenoid cartilages. Arytenoid cartilages are comprised of a pair of small three-sided pyramid that are attached to the vocal cords, along with the cricoid cartilage, a ring of cartilage that surrounds the trachea.  Arytenoid cartilages are essential to the vocal cords' movement.

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.
