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.

Answer:
RBCs' production is controlled by erythropoietin.
Mature RBCs are released into the bloodstream after approximately seven days RBCs are produced in the bone marrow
Explanation:
The hormone erythropoietin is produced and released in the bloodstream by peritubular interstitial cells of kidneys. The function of erythropoietin is to increase the number of the precursors of red blood cells and thereby to stimulate the production of red blood cells in the bone marrow. When the oxygen supply to body cells is reduced, the hormone erythropoietin stimulates the development of proerythroblasts into reticulocytes and thereby increases the RBC production.
RBCs are produced by the process of erythropoiesis and take about seven days to become mature and to be released in circulation to serve the function of oxygen delivery. The maturation of RBCs also includes the loss of most of the organelles such as the nucleus and mitochondria to accommodate hemoglobin protein. The life span of circulating RBCs is about 100-120 days.
The answer is the second choice: variation, overpopulation, adaptation
