Belоw is the diаgrаm illustrаting the regulatiоn оf erythropoietin secretion in response to oxygen concentrations in the blood. Note that in below image plus sign means stimulates and minus sign means inhibits. A. Based on the above diagram, does the secretion of erythropoietin follows a positive or a negative loop? Explain your reasoning. (1 pts.) B. What mode of secretion does erythropoietin follows: hormonal, humoral, or neuronal. Explain your reasoning. (1 pts.) C. Bob decides to move from Chicago and live in the mountains of Tibet. At regions of higher altitude such as mountains of Tibet oxygen concentrations are much lower than at lower altitudes such as Chicago. Over time would concentration of erythropoietin increase, decrease, or stay the same in Bob's blood? Explain your reasoning. (1 pts.) D. Over time what would happen to Bob's total peripheral resistance to blood flow (increase, decrease, or stay the same) as a consequence to changes in erythropoietin secretion? Explain your reasoning (1 pts.) E. What would happen to Bob's cardiac output and what will happen to diameter of his blood vessels (increase, decrease, or stay the same) when he moves to higher altitude? Explain your reasoning (describe the activating factor and receptor involved as well as output and neurotransmitter released from brain and effects at heart level and blood vessels level). (3 pts.)
Questiоn 3: Cоmpаre & Cоntrаst, аnd Applying Knowledge: Prokaryotic vs Eukaryotic regulation of gene expression Give an in-depth explanation written in paragraph form for the following questions. Each answer should be at least 3-5 sentences in length and answer all parts of the question completely. In lab, you worked with the plasmid pGLO to modify the characteristics of E.coli. Modern biotechnology often uses E. coli or other prokaryotes as manufacturers of biological materials that are important to human health. This approach works best when making proteins that can act as hormones, or signals that travel through the blood to other parts of the body, such as insulin. Type 1 Diabetes is caused by an immune reaction in the body that destroys the cells that make insulin normally. Below is a diagram for a basic plasmid that contains the genes for the alpha and beta subunits of the insulin protein. Superoxide dismutase was also included since this protein could help the effects of insulin in the body. Bacteria containing this plasmid can be grown in culture and the insulin they make can be purified (cleaned up) and then injected into a diabetic patient. Consider the other features of this plasmid that can be used for genetic engineering. Copyright 2022 by Edmonds College Department of Biology. All rights reserved.

Design an experiment to change the [promoter] on this plasmid. The current promoter is constitutive, meaning the gene is always ‘turned on.’ Instead, you want to use the promoter from the pGLO plasmid to be able to control gene expression. A complete experiment should identify specifically how the current promoter is removed, and how the new promoter is added. Also include which additional genes are needed regulate the araBAD promoter from the pGLO plasmid, and how you will select for your transformed bacteria that will contain your new plasmid. 6 pts
