For each scenario, identify the primary shift that occurs.

In the flu pandemic of 1918, roughly 3% of the population of the earth died, wiping out a large chunk of the available human capital of the planet. You can think of this as a massive decrease in the total resources available to society. What is the primary shift when this information is presented this way?

Question 5 options:

A medical researcher wants to determine if an experimental drug to control the Covid 19 Virus has any effect on the motor skills scores of human subjects. She randomly assigns patients to 1 of 2 groups. Nine hundred subjects in group 1 (the experimental group) are given an oral dose of the drug prior to testing (mean = 9.78, standard deviation = 4.05); 1000 subjects in group 2 (control group) receive a placebo (mean = 15.10, standard deviation = 4.28). Test the null hypothesis (at 95% confidence) that there is no difference between the population means of the drug group & the placebo group. What do you conclude?

Nanotechnology is a field of research and innovation concerned with building 'things' - generally, materials and devices - on the scale of atoms and molecules. A nanometre is one-billionth of a metre: ten times the diameter of a hydrogen atom. The diameter of a human hair is, on average, 80,000 nanometres. At such scales, the ordinary rules of physics and chemistry no longer apply. For instance, materials' characteristics, such as their colour, strength, conductivity and reactivity, can differ substantially between the nanoscale and the macro. Carbon 'nanotubes' are 100 times stronger than steel but six times lighter.

make a case study should consider either :

1. Methods of nano-particle manufacturing
2. Application of nano-particle in chemical engineering field.

11. Loss of heterozygosity enhances progression to carcinoma by increasing the rate of driver mutations in cancer cells. A) True B) False

12. The large increases in cancer incidence observed with certain types cancer in immune compromised individuals indicates that human tumor cells highly immunogenic. A) True B) False

13. Loss of VHL in renal cancer prevents the hydroxylation of HIF and thusly stabilizes HIF resulting in the induction of angiogenesis and the expression of glycolytic genes. A) True B) False

Tumor cells produce high levels of PD-1 to absorb PD-L1 produced by immune cells.

A)  True    

B)  False

1. The three-dimensional shape of a protein determines its function. Briefly explain these terms as they relate to protein shape and provide a supporting example for each: denature, conformational change, genetic mutation. Each example must include a specific protein.

2. Compare and contrast simple diffusion and facilitated diffusion. In other words, how are they similar and how are they different? Provide supporting examples for each.

3. (a) What is the osmolarity of a solution containing 85 mM C6H12O6, 120 mM KCl, and 24 mM CaCl2? Show your calculations. (b) What would happen to human blood cells put in the solution above? Explain.

4. Describe the stages of the cell cycle and what happens in each stage, making sure to include what is happening to the DNA. For M phase, describe all stages. If you were looking at cells under the microscope, what would you use as a distinguishing feature for each stage. Only for this last part on looking at cells under a microscope can you make a table, if you wish.

5. Describe what “Alternation of Generation” means and describe in detail the human alternation of generation. Make sure to include each of the following terms: haploid, diploid, homologous chromosomes, mitosis, meiosis, somatic cell, germ cell, zygote.

1. Based on U.S. Bureau of Justice data, 16% of persons arrested are women. If 400 arrest cases are randomly selected, estimate the probability that more than 60 women were arrested. Since this is discrete data, use the binomial distribution.

I got the answer 0.628 and it is not correct.

2. The lengths of human pregnancies are normally distributed with a mean of 268 days and a standard deviation of 15 days. If we stipulate that a baby is premature if the length of pregnancy is in the lowest 3%, find the number of days that separates premature babies from those who are not premature.

Here I got the answer 296 days and it is not correct.

Thank you

Match the ethical theory to its definition:

In your lab you are studying the kinetics of the degradation of a pain killer in the human liver. You are monitoring the concentration of the pain killer over a period of time. The initial concentration of the pain killer in your experiment was 1.51 M. After 15.58 hours the concentration was found to be 0.7550 M. In another 15.58 hours the concentration was found to be 0.3775 M (t = 31.16 hours overall).

If another experiment were set up where the initial concentration of the pain killer was 0.383 M, how long would it take for the pain killer concentration to reach 0.0205 M?

Also, for this type of problem, how can I determine the order?
