Situation: “The coronavirus disease (COVID-19) is an infectious disease caused by a new strain of coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.              On 30 January 2020, the Philippine Department of Health reported the first case of COVID-19 in the country with a 38-year-old female Chinese national. On 7 March, the first local transmission of COVID-19 was confirmed. WHO is working closely with the Department of Health in responding to the COVID-19 outbreak.” Aki and her family were alarmed with the news they watched and so first thing in the morning they rush to the nearest convenient store to secure disinfectant and sanitizers but unfortunately the store already had empty shelves of the essentials they needed. They went to other stores searching and to their dismay they acquired nothing. They were on their way home when she suddenly remembered her past lesson on “solutions”, and so she immediately ran back to…

A population numbers 16,000 organisms initially and decreases by 8.9% each year.please type answer in words don't image upload thank you.

If H (t) is the amount in (mg) of Heparin in a patient, at time t. The patient is being dosed at a rate of 4 mg/hour, and the Heparin is broken down with a half-life of 1.4 hours in the body. Which of the following is true? Hint: use the balance law: dH dt dH dt = dH dt dH - dt 4 — e-0.5t = 4t - 0.5H Net rate of change = rate in - rate out 4 - 0.5H = 4t e -0.5t

According to the diagram 1.does y intercept and slope change in noncompetitive inhibitor？ 2. does y intercept and slope change in mix inhibitor？ 3. Not sure if I draw the graph correctly，please help to correct my graph and lable out y intercept and shows if slope increase or decrease for each graph.

Although the Module says to add “5 µL of AP," this number (the volume of AP added) is meaningless by itself. What additional single piece of information do you need in order to determine how much AP is being added to the reaction? a) The specific activity of AP.   b) The mass concentration of total protein.   c) The molar concentration of AP.   d) The molecular weight of AP.

You have learned quite a number of different physicochemical methods for fractionating the contents of cellular extracts and the proteins contained within them. Which technique would be the "best" to perform the following task. Removing K+ ions from a protein sample . Oion exchange salting out differential centrifugation O gel filtration O dialysis

When reactor 4 at the Chernobyl Nuclear Power Station in Ukraine exploded at 1:23 p.m. on April 26, 1986, a great plume of radioactive isotopes erupted into the air and spread for thousands of miles. Most of the isotopes emitted immediately following the blast were of the element iodine. Which of the glands of the endocrine system would be most seriously—and immediately— affected by the blast, and how do you think this would become evident in the nearby population?

Dr. X claims that she has found a new remedy (carrot extract) to cure acne. She scores an interview with the science writer for a local newspaper, and gets a brief article written about her and her claims in that newspaper. The article does not contain any experimental evidence, but mentions that Dr. X accidentally splashed some carrot extract on her face and found that the acne was reduced a few days later. Student Y finds the article and cites it as a source for a paper he is writing for class, as evidence that acne has been cured. (a) Is this finding a fact, a theory, a hypothesis, or an observation? Explain why you think so. (b) Was it OK for Student Y to use the newspaper article as evidence for his paper? Explain why or why not.
