Which three statements correctly describe the roles of RNA molecules in the process of transcription and translation in animal
cells?
A. Small RNA molecules in the RNA polymerase catalyze the formation of
phosphodiester bonds between nucleotides in the growing messenger
RNA.
B.
Messenger RNA molecules carry genetic information from the gene in the
nucleus to the ribosome in the cytoplasm.
c. Transfer RNA molecules carry the appropriate amino acid to the growing
polypeptide.
D. Genomic RNA molecules store genetic information and transmit it to an
individual's offspring.
E. Ribosomal RNA molecules function in the assembly of the
ribosome-mRNA complex and in the formation of peptide bonds between
amino acids in the growing polypeptide.

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.
