Answer:

It is likely that this change has no effects on the protein function.

Explanation:

In eukaryotes, genes are composed of coding (exons) and non-coding  (introns) sequences. Since introns are not transcribed into messenger RNA, mutations affecting these sequences generally are neutral; however, it is important to note that introns may regulate gene expression

Yanni made a chart to compare the strong and weak forces. Which best describes Yanni’s error? Only the weak force is active in t
cluponka [151]

Answer: Option (d) is the correct answer.

Explanation:

Nucleus of an atom consists of protons and neutrons. Protons are positively charged and neutrons have no charge. So, due to the like charges of protons there occurs electrostatic force of repulsion inside the nucleus of the atom.

But due to similar number of neutrons and protons a force that is able to bind both of them together is known as strong nuclear binding energy.

This force is strong enough that it is able to overcome electrostatic force of repulsion. But when there is great difference in the number of protons and neutrons then binding force is not strong enough.

Hence, the atom becomes unstable and undergoes radioactive decay. So, this means weak forces are responsible for radioactive decay.

Thus, we can conclude that the statement which best describes Yanni’s error is that the strong force is responsible for radioactive decay.

Carine went to the doctor for a physical. Her blood pressure was 80/50. What describes Carine’s condition, and what is the most
Korolek [52]

Hello!! Since there is no mention of weight in the question, I would assume that she is pregnant. Whenever someone's blood pressure is low, it is referred to hypotension. Whenever someone's blood pressure is high, it is referred to hypertension. I would say your best answer is A - She has hypotension because she is pregnant. I hope that is the right answer you are looking for. Have a great day!! :)

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.

Which of these factors does CITES fail to consider when determining which species to cover?
xz_007 [3.2K]
The factor that CITES fail to consider when determining which species to cover is the Ecosystem sustainability.
A sustainable ecosystem is a biological environment with a series of habitats that is able to thrive and also support itself without outside influence. it is the capacity of the biosphere to meet the needs of the present generation, without hindering future generations from being able to meet their needs.
