A population of raccoons is thought to be in Hardy-Weinberg equilibrium for a tail-length gene. The frequency of the dominant allele (long tails) is 0.8. When a certain forest was surveyed, the scientist was able to tag 25 animals, which were all long-tailed. Does the lack of short-tailed animals suggest that the population is out of Hardy-Weinberg equilibrium in this forest?A. Yes, because the survey shows 100% AA individuals, so the short tils must have been selected against.B. No, because you would only expect 4 of the surveyed racoons to be short-tailed, so they may have been missed by chance.C. Yes, because 20% of the surveyed raccoons should have been short-tailed. D. No, because you would only expect 4% of the raccoons to be short-tailed, so they may have been missed by chance.

Which answer best identifies the difference between the two types of cellular transport? (B.4B) Question 3 options: Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.

A consistent response in many organisms to changing environmental temperatures is the restructuring of cellular membranes.In some fish, phosphatidylethanolamine (PE) in the liver microsomal lipid membrane contains predominantly docosahexaenoic acid, 22:6 at C-2 of the glycerol-3-phosphate backbone and then either a saturated or monounsaturated fatty acyl group at C-1. Which of the following statements are False? a. At 10 degrees Centigrade a lower percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade. b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade. . At 30 degrees Centigrade a lower percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade. d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade. e. The purpose of membrane restructuring with a change in temperature is to maintain fluidity of the membrane.
