Which statement below best summarizes the
monitta

Answer:

D. Clear-cutting would increase the amount of carbon dioxide found in the atmosphere

Explanation:

Plants including trees are organisms that help maintain the balance of carbon in the carbon cycle. They do this via the process of PHOTOSYNTHESIS, which is the way they obtain their energy and carbon source. During photosynthesis, trees (plants) absorb carbon in form of atmospheric carbon dioxide (CO2) from the air through the STOMATA on their leaves.

CO2 is an input substance in order for photosynthesis to occur. In a case where all the trees (plants) of a forest has been clear cut or removed, there will be no organisms to directly absorb the carbon dioxide (CO2) released into the atmosphere via respiration. Hence, the amount of carbon dioxide found in the atmosphere would increase.

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? A.
iren [92.7K]
The answer is <span>C.silent.

Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.
