It is A I think the insect lived first and so it is under because it is under a different layer so if they were around at the same time and the fish was just under water it would be in the same layer of rock but because it is different rock it was not around at the same time
Answer:
B. apply to all states
Explanation:
The clean water act was made in United States and states not to discharge the pollutants in the water bodies thereby protecting the water bodies from getting polluted. It also ensures to keep the water suitable for fishes and also swimming.
In this law, the federal government asks the state government to set rules for their people to discharge their waste products. However, in some states the enforcement of this law has declined over the years.
The answer should be rain water
Is the B because the skin is the mejor organ of the second line of defense
Answer:
A genetic mutation in <u>DNA</u> can lead to a change in the <u>structure and function of the protein</u> since this mutation passes through <u>transcription</u> to the mRNA —whose base sequence is altered— and in translation by the ribosomes, fewer or more or different amino acids are produced from this altered gene.
Explanation:
<u>DNA</u> is the nucleic acid that contains the genetic information of a living organism. When this molecule is affected by a mutation, the end result can be an alteration in the <u>protein structure</u> as well as in the <u>protein function</u>.
The molecular mutation consists of the change in the amount or sequence of bases that form the DNA. This alteration passes through<u> mRNA</u> <u>transcription</u>, with alteration in its normal nucleotide sequence. Since mRNA forms the codons that encode for amino acids, translation in the ribosomes produces
a protein that:
- <em>Can be longer, if the mutation is by insertion or duplication.</em>
- <em>It can be shorter, if the mutation includes a deletion or encodes the early arrest of porein synthesis.</em>
- <em>Alteration of the amino acid sequence, when it is a frame mutation.</em>
- <em>Changes of an amino acid promoted by a subtitution of nitrogenous bases.</em>
In any case, a mutation causes the <u>RNA</u> information to be altered, which can affect the <u>protein structure</u>, the <u>protein function</u> or both.
