If an atom has 17 protons, 14 neutrons, and 19 electrons, what is the atom's electrical charge?

Negative

Explanation:

Protons have a positive electrical charge and electrons have a negative electrical charge. One proton's charge is the same "strength" as one electron's charge so since there are two more electrons, it is a negative charge.

Say there were two protons and one electron. It would be a positive charge. Now I ask, if there are 43 electrons and 43 protons, would it be positive or negative? Trick question! Neither, because they cancel each other out.

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.
