Answer:
These kinds of mutations are referred to as Lethal mutations
Explanation:
This type of mutation deleteriously affects the vital genes that are responsible for the core functions of the body. The heart supplies blood to the body organs for nutrients and oxygen while kidneys filter out toxins and end products of metabolism. Mutations in genes for development of these organs will be deadly.

Bacteria, a prokaryote, has circular DNA, as do mitochondria and chloroplasts. This provides support for the Endosymbiotic Theory, which states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote).
Answer:
E-A-B-C-D
Explanation:
The steps involved in the process of bacterial transformation in the correct order are;
E. Donor cell lyses, releasing pieces of its chromosome into the environment.
A. Donor cell DNA binds to a receptor site on the recipient cell.
B. One strand of the donor cell DNA is degraded.
C. Transformed DNA pairs with homologous region on the recipient cell chromosome.
D. Transformed DNA recombines with the recipient cell chromosome.
Recessive traits would never reappear if zygotes were given opposite alleles.
<h3>What do you mean by Zygote?</h3>
Zygote may be defined as the outcome of the fusion of male and female gametes after successful fertilization.
Recessive traits are only expressed when both the copies of recessive genes are inherited from the parents.
Therefore, recessive traits would never reappear if zygotes were given opposite alleles.
