What are the tendons that connect the valves to the muscles

Chordae tendineae are the tendons that connect the valves to the muscles.

Explanation:

The chordae tendineae are cords of connective tissue that have the function of connecting the tricuspid valve and the bicuspid valve to the papillary muscles of the heart. Its tendon fibers are very resistant (approximately 80% collagen) and in the ventricular systole they are tense, preventing the leaflets from pouring into the atria and impeding the blood from returning to the corresponding atrium again.

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.
