Random mutations are an integral component of evolution. A male lion carries a mutation in 50% of his sperm that would need lead to an advantageous trait in his offspring. If the male lion successfully mates with a female lion who gives birth to 3 male cubs and 1 female cub, what is the probability that all the male cubs inherit the advantageous trait?
A. 50%
B. 75%
C. 12.5%
D. 6.25%

the answer is a or when it says crossing over

enzyme speed up the reactions

this is a good question! i'll do some research and come back when i have the answer!

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.
