Aplant species has two possible gene variations for seed shape. one plant has smooth seeds, and another has wrinkled seeds. there is a no chance that their offspring will be born with wrinkled seeds. what can you conclude from this information? a. the plant with smooth seeds is heterozygous for the dominant trait. b. both plants are heterozygous for smooth seeds. c. the plant with the smooth seeds is homozygous for the dominant trait. d. one parent is homozygous, and the other is heterozygous for the dominant trait. e. both genes are codominant in the offspring.

The kidney filters potentially toxic substances in the blood, and thus “clears” the blood of those substances. this clearance function is dependent upon and proportional to the diffusion gradient of the substance across filtering capillaries, i.e. if the concentration of the substance is doubled, twice as much will be cleared from each ml of blood that is filtered. suppose that the body produces a constant amount of a substance x per unit of time. the kidneys eliminate substance x at a rate directly proportional to the concentration of the substance and the volume of blood cleared each minute (c): elimination = c × [x], where [x] is the steady-state concentration of substance x. imagine an individual with an initial concentration of x equal to [x]0 who develops kidney disease. her baseline clearance c0 drops to one half of the original (½c0). what is the new steady state concentration of x? (for simplicity, assume that substance x is 100% filtered by the kidney).

50 points! which of the following is an inference? a burning candle is extinguished when it is covered with a jar. the candle burns longer than expected in a jar that has a plant in it. a plant lives longer than expected in a jar that has a burning candle. there is more oxygen in the jar because there is a plant in it.
