Question:
Consider that in horses a single pair of genes controls gait. Some horses can only exhibit a trotting gait, while others exhibit only a pacing gait. In an attempt to determine the pattern of inheritance displayed by this trait, a horse breeder crossed a stallion (\male) that came from a long line of pacers to several mares (\venus) that were trotters. All of the foals were trotters. Which gait is under the control of the dominant gene? Using the letters T and t to represent the dominant and recessive genes, respectively, identify the genotypes of the stallion, the mares and the foals.

Options:
A. Trotting gait is controlled by the recessive gene, t. The genotype of the stallion is TT, that of the mares is tt, and the genotypes of the foals is Tt.
B. Pacing gait is controlled by the recessive gene, t. The genotype of the stallion is tt, that of the mares is TT, and the genotypes of the foals is tt.
C. Pacing gait is controlled by the dominant gene, T. The genotype of the stallion is Tt, that of the mares is tt, and the genotypes of the foals is Tt.
D. Trotting gait is controlled by the recessive gene, t. The genotype of the stallion is TT, that of the mares is Tt, and the genotypes of the foals is tt.
E. Trotting gait is controlled by the dominant gene, T. The genotype of the stallion is Tt, that of the mares is TT, and the genotypes of the foals is TT.
F. Trotting gait is controlled by the dominant gene, T. The genotype of the stallion is tt, that of the mares is TT, and the genotypes of the foals is Tt.
G. Trotting gait is controlled by the recessive gene, t. The genotype of the stallion is tt, that of the mares is Tt, and the genotypes of the foals is tt.
H. Pacing gait is controlled by the dominant gene, T. The genotype of the stallion is tt, that of the mares is Tt, and the genotypes of the foals is Tt.
I. Pacing gait is controlled by the recessive gene, t. The genotype of the stallion is Tt, that of the mares is TT, and the genotypes of the foals is Tt.
J. Pacing gait is controlled by the dominant gene, T. The genotype of the stallion is TT, that of the mares is tt, and the genotypes of the foals is Tt.

Question:
Mr. A owns 1,000 shares of General Electric common stock. If he tries to sell some, he finds he can get a price of $61.50 per share for all 1,000 shares. If he offers only 500 shares, he can get a price of $61,625 which is $0,125 more per share. That is, reducing his amount sold by a half, he can get a price that is higher by about 1/500. If he sought a price of $61.75, he would sell nothing. Mr. A considers this an insignificant rise in price as a result of withholding his supply. Is this an example of a price-takers' market? Compute Mr. A's marginal revenues as best you can with the given data.

Options:
A. Yes, this is an example of a price-takers' market, Marginal revenue is $61.50 per share

Question:
A 2.0 L flask holds 0.40 g of helium gas. If the helium is evacuated into a larger container while the temperature is held constant, what will the effect on the entropy of the helium be?

Options:
A. It will increase as the gas molecules will be more dispersed in the larger flask.
B. It will remain constant as the helium is simply transferred to a larger container.
C. It will remain constant because the volume of the flask does not affect entropy.
D. It will remain constant as the number of helium molecules does not change.
E. It will increase as the temperature is held constant.
F. It will decrease as the pressure of the gas will decrease in the larger flask.
G. It will decrease as there will be fewer collisions between the helium molecules in the larger flask.
H. It will decrease as the gas will be more ordered in the larger flask.
I. It will decrease because the molecules will collide with the sides of the larger flask less often than they did in the smaller flask.
J. It will increase because the molecules will collide with the sides of the larger flask more often than they did in the smaller flask.
