Question 1

Let’s start with a relatively straightforward one – and make it topical.

1. Briefly explain what qPCR is and why it is different than traditional PCR. Address what the q stands for and why the technique is sometimes called real-time pcr.

Unfortunately – that real-time moniker became a problem because some people shortened it to RT-PCR.However, most usage of RT-PCR is something distinct from qPCR.

2. Describe that something else RT-PCR.

You can combine qPCR and RT-PCR – producing RT-qPCR. One application of RT-qPCR is detection of certain viruses – such as COVID-19.

3. For this application, describe why RT-qPCR is preferable to qPCR.
4. For this application, describe why RT-qPCR is preferable to RT-PCR.

Is there any evidence that individual stickleback acclimate to variation in trout predation presented here. Identify potential acclimations to trout predation.

For assistance with my studies, what is the homologies of sclaes types between chondrichyans (placoid sclaes), actinopterygians (ganoid sclaes, teleost scales), aquatic sarcopterygians (cosmoid scales), and reptile (epidermal scales)?

1. Identify similarities and differences between the Hyponatremia caused deaths of Cynthia Lucero and Jennifer Strange. Be sure to include details regarding presentation of symptoms and the circumstances that led to their deaths. (50+ words minimum).
2. Identify methods to best restructure the "Hold your Wee for a Wii" contest that Jennifer Strange participated in to prevent future Hyponatremia deaths. Just not doing the contest will not be accepted.  (50+ words minimum).

In what circumstances would it be justifiable to compel vaccination against a newly emergent pathogen, e.g., an especially virulent coronavirus, through mandates and criminalization? Discuss ethical, health, & social issues.

Suppose you invented a drug that blocked the production of LH from the anterior pituitary.  

1.  How would this affect the menstrual cycle?

2. Would this drug be a good method for birth control? Why?

Most of these fatty acids increase blood cholesterol levels by raising LDL cholesterol

These fatty acids raise LDL cholesterol while reducing beneficial HDL cholesterol

These fatty acids generally lower LDL cholesterol and raise HDL cholesterol

These fatty acids will lower LDL cholesterol, but in some people, they may also cause a decrease in beneficial HDL cholesterol

A student is doing some research on the importance of agents used in the laboratory room to kill certain prokaryotes and eukaryotes. Can you list the six different agents and what each specializes for?

In the fruit fly D. virilis, the mutations dusky body color (dy), cut wings (ct), and white eyes (w) are all recessive alleles located on the X chromosome. Females heterozygous for all three mutations were crossed to dy ct w males, and the following phenotypes were observed among the 500 offspring.

14) What are the genotypes of the two maternal X chromosomes, with the genes in the correct order?

a) dy + w / + ct

b) dy + + / + w ct

c) dy w + / + ct

d) dy w ct / + + +

e) + ct + / dy + w

15) What is the recombination frequency between dusky and white?

a) 148/500

b) 46/500

c) 43/500

d) 49/500

e) 40/500

PLEASE EXPLAIN!!!! CLEARLY!!!

Describe a spore forming bacterium stained with the endospore stain and magnified 1000X.

Describe the spore and vegetative cell and note the colors you would expect to see using the stains we performed. What would you expect the Gram reaction of this cell to be?

How does recombination impact genetic variation in future generations including crossing over and meiosis?
