5. Non-animal marine organisms are primarily , in part due to the buffering effects of water
that protects them from the mutagenic effects of UV light
a. haploid
b. diploid
c. multicellular
d. developmentally complex
e. drikaryotic

UV light can not only severely damage frogs, but is also one of the main killers of them. The UV rays cause sub-lethal effects such as slow growth rates and immune dysfunctions. UV light effects all types of amphibians, mostly frogs, in all negative ways.

Explanation:

the unequal cytoplasmic division that  results  in  one egg  and three polar bodies ensures that a fertilized  egg has  ample nutrients  forits journey  to  the uterus.

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.
