Sry guy, can't find a subject for this - so I put under Biology

Pls do not handwrite the answer, this is for easy reading

Qns:

What does medicine contribute to technology/sciences? (E.g biomimicry in structures, A.I learning patterns)

According to A Short History of Humans and Germs, most major human diseases developed and spread when humans began living in large cities with populations of up to 500,000.

Discuss fire as a mechanism of secondary succession and how a natural fire can enhance species diversity of a forest. Use the Intermediate Disturbance Hypothesis.

CF carrier frequency estimations in American Hispanic populations • Carrier screening kits for Cystic Fibrosis alleles have been updated to include more probes (CFTR 60 kit 2) • It is reported to have a detection rate of 83.7% in Hispanic American populations.

The same group have a CF incidence of 1 in 9,500. Given the above, determine:

1) CF carrier frequency in the Hispanic American population.

2) Estimate the probability of being a carrier if a CFTR 60 kit result is negative for a member of this population.

3) Estimate probability of a child with CF being born if one parent is a known CF carrier and the other is Hispanic and found to be negative when tested with the CFTR 60 kit.

Explain why many extreme halophiles use KCL (instead of NaCl) as their compatible solute. [SHORT ANSWER]

What are nucleotides? How do nucleotides contribute to genes and chromosomes?

Why is the trinucleotide sequence, CAG, important in Huntington Disease?

When we study the effects of chronic stress on human health, most of our chronic stress is imaginary, meaning, it's made up by our imagination and conscious thought, created by the Frontal lobe. Discuss, why frogs and lizards cannot experience chronic stress like that? In 100 words or more.

With reference to the structure of hemoglobin and your knowledge of complex
formation reactions, discuss the stability of oxygenated hemoglobin versus
deoxygenated hemoglobin. Be sure to fully outline your reasoning.

Write down the equation for the production of NADPH and Ribose-5-P in the Pentose Phosphate Pathway(PPP) and the PPP's biological significance :)

You have been cultivating snapdragons in your garden and allowing plants to re-germinate each year from seeds dropped by the previous year’s annual plants. You know that white flowers are recessive and count 9 white flower plants out of 100 that you examine. Do you find evidence for evolution acting in your population? If yes, could natural selection be involved?

Can we calculate using HWE here or we can't because if we calculate q^2 then we are assuming the population is in HWE. I was also thinking along the lines that if we calculate q , it wouldn't only be for homozygous recessive but also for heterozygous, thats why we can't know what proportion of q is homozygous recessive and thus compare it to original number of white flowers to see if evolution is happening. please tell me if this is correct or wrong.

AND PLEASE DONT ANSWER IF YOU AREN'T 100% SURE OF THE SOLUTION. ive seen answers to this question on chegg and im sure it ISNT correct. Thanks, ill definitely give you a thumbs up!

1. A vaccine to COVID-19 is perhaps the best way to end the pandemic. Please answer the following questions in a way that you might explain it to an intelligent patient who is asking the following questions.

a. What is a vaccine?

b. How will a vaccine help to prevent me from getting COVID-19?

c. There are more than 90 vaccines being developed against COVID-19. Three types of vaccines currently being investigated for COVID-19 are a subunit vaccine OR a RNA vaccine OR an inactivated vaccine. Choose one and explain what it is.

If I conditionally knockout FGF8 in the somatic and lateral plate mesoderm of a mouse during the onset of limb bud formation what would the resulting phenotype look like? What about if I knocked out Shh instead?

Compare the F and Hfr transfer.
