The black color cost in hamsters is due to a dominant gene (B)..
A recessive allele (b) at this locus results in a brown coat when homozygous (b/b). However, neither coat color is expressed when the organism is homozygous for the allele (a) at a separate locus. The a/a genotype results in a white (albino) coat, regardless of the allele at the B locus. The wild-type allele (+) at the (a) locus allows normal coat coloration, whether the genotype is +/+ or +/a.
The following experiments were performed to better understand these relationships.
Experiment 1:
A female hamster with the genotype B/B; +/+ is crossed with a male hamster of genotype b/b; a/a.
Experiment 2:
Female offspring from the cross in Experiment 1 were backcrossed to the (b/b; a/a) parent. The distribution of coat coloration among the progeny was as follows; black (66), brown (34), and white (100).
2. A true-breeding strain of black hamsters is available. What is the genotype of this strain?
A. B/b; +/+
B. B/b; +/a
C. B/B; +/+
D. B/B; +/a
3. A strain of hamsters known to be homozygous (b/b; a/a) at both loci is available. What is the phenotype of these animals?
A. Black
B. Brown
C. White
D. A mixture of white and brown
4. What will be the phonotype(s) of the F1 animals resulting from the cross in Experiment 1?
A. All black
B. All brown
C. All white
D. Both black and brown
5. Experiment 2 suggests that the two genetic loci discussed in the passage are:
A. linked
B. unlinked.
C. recessive.
D. Not enough information to determine linkage.
6. Based on the results from Experiment 2, what is the genetic map distance (frequency of recombination) between the two loci discussed in the passage?
A. 17 centimorgans
B. 34 centimorgans
C. 68 centimorgans
D. Impossible to determine; they are unlinked.

The manager of a local hamburger restaurant wants to study customer demand for V-Burgers, a new meatless hamburger. The salesperson for V-Burgers claims that 75% of people who normally eat hamburgers also like V-Burgers. The manager surveyed a random sample of 92 customers who have eaten V-Burgers and found that 54 of them said they would buy one again. Does this data indicate that the salesperson’s claim is too high? Use a 5% level of significance

Consider the reversible Carnot cycle shown in the following figure given below with 1.19 mol of an ideal gas with C V,m =5R/2 as the working substance. The initial isothermal expansion occurs at the hot reservoir temperature of T hot = 890 K from an initial volume of 3.85 L ( V a ) to a volume of 10.5 L ( V b ) . The system then undergoes an adiabatic expansion until the temperature falls to T cold = 298 K . The system then undergoes an isothermal compression and a subsequent adiabatic compression until the initial state described by T a = 890 K and V a = 3.85 L is reached. Calculate Vc, Vd , wab,wbc,wcd,wda,wtotal for this step in the cycle. Calculate E . Calculate the amount of heat that is extracted from the hot reservoir to do 1.00 kJ of work in the surroundings.
