Base your answer to the following question on the passage below which describes an ecosystem in New York State and on your knowledge of biology.

The Pine Bush ecosystem near Albany, New York, is one of the last known habitats of the nearly extinct Karner Blue butterfly. The Karner Blue butterfly's larvae feed on the wild green plant, lupine. The larvae are in turn consumed by predatory wasps. The four groups below represent other organisms living in this ecosystem.

The Karner Blue larvae belong in which group?

Mike has four aquatic plants of the same size and same species. He submerged the plants in a separate beaker filled with 200 ml of water. He then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant with the beaker under the most intense light gives off the most gas bubbles in a 20-minute period. Which of the following statements best explains Mike's observations?

Two test tubes were filled with a solution of bromothymol blue. A student exhaled through a straw into each tube, and the bromothymol blue turned yellow. An aquatic green plant was placed into each tube, and the tubes were corked. One tube was placed in the dark, and one was placed in direct sunlight. The yellow solution in the tube in sunlight turned blue, while the one in the dark remained yellow.

Which statement best explains why the solution in the test tube placed in sunlight returned to a blue color?

A weightlifter is using heavy weights in short bursts for a competition. Because his muscle cells are not able to take enough oxygen to make very much ATP the weightlifter begins to get fatigue in his muscles.

Which of the following processes is most likely going on in the muscles of the weightlifter as he competes in his event?

Green onions that are left in a dish of freshwater for several hours become stiff and remain standing upright. Therefore, the freshwater is __________because water is entering the cells to make them turgid (stiff). Similar green onions left in a saltwater solution become soft and wilt. The salt water is __________ because water is exiting the cells to make them flaccid (soft).
