Researchers use the denaturation temperatures of hybrid double helices to compare evolutionary relatedness. Complementary strands denature at 95 degrees Celsius. A researcher engineers a hybrid double helix from two species, and it denatures at 93 degrees Celsius. What does this mean?A. The hybrid double helices are more complementary than the non-hybrid.
B. The hybrid double helices are less complementary than the non-hybrid.
C. The species are more closely related than any other two species.
D. The hybrid strands' base pairs had fewer mismatches.

where is the diagram?

if you insert the diagram ill be able to you

your answer is "the 1950's"

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.
