Which statement below best describes the role of mutations in evolution by natural selection? A Mutations increase the genetic variation within a population, and each of the variants provides an advantage under different circumstances
B Mutations increase the genetic variation within a population, and some of the variants may provide an advantage to individuals over time
C Mutations help stabilize the genetic variation within a population, and only one or two variants generally provide an advantage to individuals.
D Mutations help reduce the genetic variation within a population, and thus increasing the rate that new adaptations develop.

Answers

The role of mutations in evolution by natural selection is option b. Mutations increase the genetic variation within a population.

Role of mutation in evolution:

The mutation is significant as the first step of evolution since it developed the new DNA sequence for the specific gene that developed the new allele.

Also, at the same time, it rise the genetic variation within the population also it provides as an advantage to individual

hence, the option b is correct.

What do you call the chemical reactions that resulted in the digestion of human flesh?

Answers

Final answer:

The digestion of proteins, including human flesh, involves enzymatic processes performed by proteases. These begin in the stomach with pepsin and continue in the small intestine with enzymes like trypsin.

Explanation:

The chemical reactions responsible for the digestion of proteins, including human flesh, are primarily enzymatic digestion processes performed by proteolytic enzymes, known as proteases. The process begins in the stomach where the enzyme pepsin starts the breakdown of proteins into smaller chains called polypeptides. This process continues in the small intestine where other proteases, like trypsin and chymotrypsin, further break down these peptide chains. Finally, the smallest units of proteins, amino acids, are absorbed into the bloodstream.

UCU-CGA-GCC-GUU-GGG-UGA how do I convert this into an amino acid using the codon chart, i've been on this forever

Answers

So u get a codon chart it'll look like a circle with a bunch of letters. Then you use the letters u are given for every dash such as UCU and you go biggest to smallest letter until you hit an amino acid or stop then what you write down is that amino acid you hit. For an example, we'll use UCU. You go to the big letter U inside that big U will be a smaller C and inside that C will be a smaller U which leads to an amino acid or a stop codon. And you do this with every group of 3 letters. If one is missing it stops prematurely and if there is an extra when it may have a mutation. I hope that helped! If not there are YouTube videos out there that can help.
