The punnett square predicts the ratio of genotypes in the offspring, based on the genotypes of the parents. the punnett square below examines the chance of offspring having freckles, which is a dominant trait. a punnett square is shown. the columns are labeled upper f and f. the rows are labeled upper f and f. clockwise from upper left the boxes contain: upper f upper f, upper f f, upper f f, f f. based on the punnett square, what is the probability that the offspring will have freckles?

Ascientist is conducting an investigation that involves water, silver, carbon dioxide, and oxygen gas which group of statements best describes all of the materials he is using in the investigation?

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).
