Alina [70]

Answer:

True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.

Explanation:

  • An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
  • Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
  • Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.

In meiosis, it happens twice and occurs in metaphase 1 and metaphase 2

An mRNA sequence reads: GAA/GCU/AUA/CUA/UGU. What would the effect on the amino acid be if the second codon read GCA instead, an
Murrr4er [49]

Answer:

D) Silent mutation on second codon, third amino acid changed from ILE to ASN.

Explanation:

Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]

On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
