Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).

Clear cutting has a similar effect as controlled burning of a forest. True False
zysi [14]

The correct answer is false and here is why:

Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.

Controlled burns have a completely different affect. They burn the under brush to help keep the soil rich with nutrients, plus they also help to prevent large crown fires that burn down whole forests from happening.

Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
