Answer:
The following are the cause, consequences and solution of the question:
Cause:
The cause may be defined as the reason due to which the situation arises. The factors that are responsible for the dead zones are the nutrient runoff from the agriculture and industrial waste that causes the algal bloom.
Consequence:
The consequences are the result of the harmful situations. The consequences of dead zone are aquatic organisms death, shifts of the marine food web and fisheries loss.
Solutions:
Solutions are the steps that might taken to solve the problem. The solutions that might taken to solve the dead zone problem are the reduction in the use of fertilizers, wetland constructions and development of the different polices.

Answer:
A. Yes, we will see growth. Yes, they will glow.
Explanation:
pGLO plasmid was engineered to be used as a vector in the field of biotechnology. It has an ampicillin resistance gene which acts as a reporter gene. It also has another reporter gene, GFP which shares its promoter (araC) with the gene responsible for metabolizing arabinose. GFP gene is thus translated only in the presence of arabinose in the medium since the promoter is active only in the presence of arabinose. Once the GFP gene is translated, the colonies glow with green fluorescence under UV light.
Here, the <em>E.Coli</em> colonies were grown successfully on LB + Ampicillin + Arabinose plate so they were ampicillin resistant. They also glowed in UV light. If these transformed colonies are inoculated in another LB + Ampicillin + Arabinose plate they will be able to grow successfully since they are ampicillin resistant. They will also glow because the new plate also has arabinose so the araC promoter will be active and expression of both GFP gene and arabinose metabolizing gene will occur.
I believe the answer is answer D- Nuclear decay rates are constant.
~ Good luck!
Correct answer: D). Deletion
Tay-Sachs disease is an autosomal hereditary disease that is known to affect the central nervous system. It results from the mutation caused in the gene that encodes for the beta-hexosaminidase enzyme. It is a lysosomal enzyme that is composed of the beta and alpha polypeptides.
It is caused when both the parents are a carrier, it occurs when a baby is born in absence of hexosaminidase. It affects the nervous system and can change the physical appearance after a few months of the birth.
