Why is glycolysis critical for the energy metabolism of both aerobic and anaerobic organisms?

Write an essay on Coronavirus COVID-19 pandemic and its effect on “Sex Industry” (Sex workers). For this essay assume that most of the sex workers are “women”. Write in no less than 1 page & no more than 2 pages

How many gross and net molecules of ATP will one get from complete oxidation of a saturated fatty acid that has 18 carbons? Please show all the detailed steps (which step of aerobic respiration) and calculations that you will be doing to arrive at your answer to get full credit. I need to see the energy balance sheet for each step, involved in this oxidation (check the energy balance sheet for glucose in text book to get idea of how to organize your data). Note that you have to give me two separate answers. Read question carefully.

Question 7

What is the difference between polarity and segmentation?

Select one:

a. Polarity describes a relative location, while segments are fixed positions

b. Polarity is established by gene expression regulation, while segmentation is regulated by epigenetics

c. Polarity exists throughout an organism, while segmentation only applies to individual cells

d. Polarity describes the body, while segmentation describes appendages (limbs)

Walk through the the process for how nucleotides and ribose are made and show how these come together to make ATP used for DNA replication. You must start from glucose and CO2 as your starting materials, everything else must be made from these compounds. Would appreciate answer with drawing as well as written explanation.

What cellular features are retained if the plant cell is alive?

How would an ecosystem be affected if a new tertiary consumer were brought into the ecosystem? Be specific and include details about how each trophic level would be impacted.  

pick  5 Chemistryanalytes (Example: Troponin) and describe the following for each analyte:
1. Normal range
2. Units in which analyte is reported
3. Disease caused by increased or decreased value
4. Does Hemolysis affect the test result?
5. What color tube is required for the analyte testing

Non-homologous end joining (NHEJ) and Homologous recombination repair (HRR) are important DNA repair mechanisms in the mammals. With diagrams, explain how the repairs are carried out in NHEJ and HRR. Are they completely independent pathways? Justify your answer with specific examples.

List conditions of site-specific recombination that result in integration, excision, and inversion respectively, in terms of the shapes of DNA and orientations of the target site.
