Answer:
G
Explanation:
your have to look at the second triplet of bases: AGT since it says the chain is only 2 amino acids long (so the 3rd triplet must be the stop codon).
Now remember that for the DNA-mRNA transcription A becomes U, T becomes A, C becomes G and vice versa. So to codify a UGA codon you need ACT in the DNA. Since we have AGT instead, it means the G was changed by the mutation.
Uneven aged trees are like the even aged but the only difference is that uneven aged trees are cut at various time and not at the same time. This is to promote regrowth of other trees by seeding and being a shelter for those undergoing regrowth.
Answer:
Because of the natural selection
Explanation:
Variation in nature is all we can found out there. Through millions of years nature went with the survival of the fittests, like Darwin said.
When we talk about artificial selection, we talk about humans getting involve on that selection, but we deppend on variation in nature. We can't "create" a new species, but we do can choose the genetic traits we want to prosper and which no.
