Ascientist publishes a paper that states that changes in the levels of gases in the atmosphere of a moon of saturn indicate that there may be extraterrestrial life on that moon. which statement correctly answers whether the question of alien life on this moon is scientific?

a. the question is not scientific because it cannot be tested without going to the moon of saturn or sending a probe there.
b. the question is scientific because it deals with astronomy.
c. the question is not scientific because it involves alien, extraterrestrial life.
d. the question is scientific because it is testable and verifiable.

The correct answer is:

D. The question is scientific because it is testable and verifiable.

I just took the Unit Test Review and got it right.

Hope this helped :)

explanation:

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.
