Answer:
A
Explanation:
From what I know this could be wrong, but in the four stages of natural selection, the first step is overproduction, the second step is adaptation, and the third step is competition or survival of the fittest. This means that only the organisms with the best adaptations for their surroundings will survive. COULD BE WRONG SORRY IF IT IS
Most of legumes have symbiotic, nitrogen-fixing<span> bacteria, that live in structures called "</span>root nodules"<span>. </span>
I believe it’s the first, third and fourth ones. I might be wrong and I’m sorry if I am.
Answer:
See the answer below please.
Explanation:
There are different types of mutations:
- Substitutions: the exchange of one base for another occurs (eg changes a C for an A), which could lead to a codon change that codes for a different amino acid causing changes in nascent protein, generating a codon that codes for the same amino acid without any change in nascent protein; generate a different codon for the amino acid: a stop codon and cause an incomplete protein to form.
-Insertions: base pairs are added to the DNA sequence.
-Deletions: base pairs are removed from the DNA sequence.
