The following experiment is used for the corresponding question(s).A researcher discovered a species of moth that lays its eggs on oak trees. Eggs are laid at two distinct times of the year: early in spring when the oak trees are flowering and in midsummer when flowering is past. Caterpillars from eggs that hatch in spring feed on oak flowers and look like oak flowers. But caterpillars that hatch in summer feed on oak leaves and look like oak twigs.How does the same population of moths produce such different-looking caterpillars on the same trees? To answer this question, the biologist caught many female moths from the same population and collected their eggs. He put at least one egg from each female into eight identical cups. The eggs hatched, and at least two larvae from each female were maintained in one of the four temperature and light conditions listed below.In each of the four environments, one of the caterpillars was fed oak flowers, the other oak leaves. Thus, there were a total of eight treatment groups (4 environments × 2 diets).Refer to the accompanying figure. Which one of the following is NOT a plausible hypothesis to explain the differences in caterpillar appearance observed in this population?

Although the textbook uses absolute value bars around the formula for percent error, I suggested that it is usually preferable NOT to use absolute value bars. What extra information are we losing by using the absolute value bars?

While experimenting with the fan carts, one setting of the fan resulted in an acceleration of 1.22 m/s2 when the mass of the cart was 735 grams. Calculate the expected acceleration if we add two 120 gram masses to the cart.
