Cystic fibrosis is a rare disease caused by homozygosity for a recessive allele, and characterized by a build-up of mucus in the lungs and difficulty breathing. A woman whose maternal uncle had the disease is trying to determine the probability she and her husband could have an affected child. Her husband's sister died of the disease. Assuming the uncle and the sister are the only family members who had the disease, what is the chance that the couple's first child will be affected? I'm getting 1/18, but chegg says 1/64? Please verify it is 1/64 for the answer.

You’re working with an mRNA transcript and want to characterize precisely where initiation of translation starts and where RNA binding proteins interact. Explain the experimental approach you’ll take to do this.

1) You study a deadly disease in your community; Methicillin-resistant Staphylococcus aureus (MRSA). It is usually contracted in in-patient facilities.

1. Compare the primary role of Mg²⁺ [ Mg(II)] in the mechanism of restriction endonucleases with that of Zn²⁺ in the carbonic anhydrases.
2. Explain the role of Ser 236 in abstracting a proton from the attacking water and giving up a proton to the Mg²⁺-ATP complex.

Phylogenetic Reconstruction - Please provide a behavioral phylogenetic reconstruction of these groups of birds (how the Darwinian Finches evolved) beginning with a common ancestor moving towards the bird with the most complex behavior (in your opinion). Here, I am looking for the behaviors that lead to the morphologies that we see.

Cindy is a thirty-five-year-old volunteer in an inner-city church-sponsored preschool program. The mothers of the neighborhood are encouraged to bring their children to the program for a “time out.” Most of the children are present on an irregular basis one or two times a week.

            One day, Zach, a 2½ year-old became ill during his stay. A rash of small red spots that were not raised above the skin surface was observed during his changing, and he had a slight fever. His mother was located and encouraged to take him to the local clinic.

            Shortly after this, Cindy confirmed what she had suspected for about a month—a home pregnancy test was positive. At her visit to the obstetrician, Cindy relayed the story of Zach’s illness to the nurse when asked if she had recently been exposed to any illnesses. Cindy had not been overly-concerned about Zach’s rash but had seemed to be mildly ill herself about three weeks after that incident. The obstetrics nurse seemed to be very interested in this exposure and said that they would contact the clinic and see if Zach had visited and been diagnosed. Blood tests were also ordered for Cindy.

Laboratory Results

            The initial hemagglutination inhibition test indicated an antibody titer of 1:16. Subsequent sera collected 10 and 21 days later showed no significant change. There was no significant level of IgM-specific antibody detected.

Which of these is most characteristic of Zach’s symptoms

Just answer the question in General. Don't need to use the graph

1. Why can you kill the moths off in a few time steps? What does this indicate could happen in an environment to cause a species to go extinct?
2. How could the model be modified so that the proportions of each moth color type would not change through time?

A) What are five protists that might be found in pond water (other than Euglena, paramecium, giardia, amoeba, and slime mold)? B) What does each look like, what locomotion does each have, how does it obtain food, and where would you find it in the water?

What challenges might be faced from non-clinical personnel?

In the production of sperm, what happens to spermatocytes?

   a. They undergo mitosis to produce sperm cells.

   b. They undergo meiosis to produce sperm cells.

   c. They are sperm cells so they become part of semen and are ejaculated.

   d. They develop into self-renewing stem cells that maintain the testes.

Do women produce more eggs or do men produce more sperm? Why?  

a. Women produce more eggs because the odds of any one egg getting fertilized by a sperm are not good.

b. Women produce more eggs because they can’t move and so are stuck in one place. Because sperm can move, not as many are needed.

c. Men and women produce about equal amounts of sperm/eggs.

d. Men produce more sperm because they produce it all their lives, while women are born with all the eggs they’ll ever have.

Where do the hormones FSH and LH come from and what do they do in women?

a. The pituitary gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

c. The prostate gland; FSH causes a follicle in the ovary to mature and release an egg, and with LH, stimulates estrogen secretion.

d. The ovary; FSH causes a follicle in the ovary to mature and release an egg, and LH stimulates estrogen secretion.
