Humans carry a variety of non-functional genetic sequences, called processed pseudogenes, in their DNA. We can estimate how long ago these sequences first appeared in the genomes of our ancestors. In humans, processed pseudogenes include the three options below. Which of these would be most widespread among other primate species?a. alpha-enolase psiy (11 million years old) b. AS psiy (16 million years old) c. CALM II psiz (36 million years old)

i believe it is "they are not used up by reactions" as the answer to your question, text me back if this is correct because i just learned this.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

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.
