What is the difference between a woman with 45, X and one with 46, XX given that in all of the cells of a 46, XX individual one X chromosome is inactivated anyway?

Girls with Turner's syndrome are a little shorter than average, have a thicker neck, usually can't have children and can be socially inept - they butt into conversations, misread body language, are insensitive to others' feelings… In essence they act a lot like boys. Why might this be? (Hint: where do boys get their X chromosome?)

Using the parental Meiotic Nondisjunction rates from the class powerpoint make an argument about the % of Turner’s individuals that are socially inept versus socially competent.

8. Imagine a lake receives acid rain for an extended period of time. The original pH of the lake was 6, but it has now dropped to pH 3. How many times more acidic has this lake become? What negative impacts can this amount of acidification have on the environment?

What is responsible for the transition from the occasional or initial drug taking to habitual drug taking, and why does this not occur in everyone who has used addictive drugs? What is the

difference between the positive incentive value of a drug and the hedonic value of a drug?

Cystic Fibrosis is a disease caused by a defect in a Chloride ion transport channel protein. The channel performs a critical function in the lungs; thus, disease sufferers have trouble clearing mucous from their lungs, leaving them susceptible to opportunistic infections.

Discuss how this protein may function (normally) in the lung & hypothesize on possible treatment schemes.

What can we learn from the story of Titus about each of the following: (a) the importance of females in gorilla troop social structure (10 points) ; (b) how males compete for dominance - physically (5 pts); sexually (5 pints); socially/politically (5 points); genetically (5 points).

In Drosophila melanogaster, black body (b) is recessive to gray body (b+), purple eyes (pr) are recessive to red eyes (pr+), and vestigial wings (vg) are recessive to normal wings (vg+). These three genes are linked with pr located between b and vg at a genetic distance of 6 cM from b and 13 cM from vg. Previous experiments have shown that the interference associated with these three genes is 0.5. A fly with a black body, purple eyes and vestigial wings is crossed with a fly with a gray body, red eyes and normal wings. All of their F1 progeny is wild-type. The F1 females are mated with male flies that have black bodies, purple eyes and vestigial wings. Ten thousand progeny are produced from this testcross. How many of the testcross progeny are expected to have purple eyes but be wild-type for body color and wing type?

Describe the 4 levels of structure of a protein and describe how the R groups influence these structures.

how does dna work

I have sequenced roughly 24 genomes from two different continents (Africa and South America), specifically for the envelope gene of yellow fever virus. I used software to generate the dN and dS ratio for each continent

Africa: (dS= 0.2065, dN= 0.0031.) dN/dS ratio= 0.0150

South America: (dS=0.5541, dN= 0.0112.) dN/dS ratio= 0.0202

Im unsure how to interpret these ratio's, and how the difference in the two suggests any differences in the type of selection for the enveloped protein in each continent.

What is the basic constraint in recombination dictated by the 12/23 rule? Why does V_kjoin to J_konly, and V_lto J_l only, and V_H to D_H to J_H only?

1. Some traits are not transmitted via Mendelian inheritance. Describe three forms of inheritance that do not follow Mendelian inheritance or laws. Hint: These are alternative to dominance and recessivness.

1. Use a Punnett’s squares to show a monohybrid cross between pure breeding parents of tall (T) and dwarf (t) pea plants. The tall trait is dominant and thus is represented by the uppercase letter “T”. The dwarf trait is recessive and is represented by to lowercase letter “t”.

2. You have a pea plant with purple flowers but you are unsure of it’s genotype. Since purple flowers is the dominate trait (P), while the recessive trait is white flowers (p), you decide to conduct a test cross to determine the genotype of the purple flowered pea plant. Show how you would do this.

For The introduction include

1) Background about bacteria. specifically the differences between gram + and gram - bacteria. Talk about B. subtilus and E. coli (what they are?)

2) Background on antibiotic resistance, How it formed and how is it affecting the society

3) State the objective of this experiment

4) predictions- please use what I wrote on the board. predictions need to be rationalized, not opinion oriented.

Please write this in order 1, 2, 3, 4. Make sure the organizations are good. also

- Include reference, literature reviews

-No question form

-Paragraph-wise

Methods

-Need to be PASSIVE, don't use I, you, we, the professor

-Make sure you use the correct and precise term

-Please don't divide them into sections, need to be in paragraph

-Need to mention the type of antibiotic used, bacterias used

-Treat this like a real lab experiment

-Don't mention we wait a week. After incubation, it's the measure of ZOI. and that's it.

-Don't be excessive. Only write enough so someone could replicate your experiment.
