The triplet code can produce 64 possible codon combinations. what is an advantage of this? a. every single codon specifies more than one amino acid. / b. every single amino acid has more than one codon. / c. the first two bases of the codon specify the amino acid.

The answer is B. Every single amino acid has more than one codon.

There are 20 different amino acids, but there are more than 20 combinations of three nucleotide bases on DNA. There are 64 different combinations of three nucleotide bases on DNA, which is about 3 times more than the number of amino acids. Therefore, every single amino acid has more than one codon is the right answer. But, it should be taken into consideration, that 2 out of 20 different amino acids have only one codon - methionine and tryptophan.

answer; i believe the correct answer is (anemia);

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.
