Question 26

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.

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 feed on the wild green plant, lupine. The butterflies are in turn consumed by predatory wasps. The four groups below represent other organisms living in this ecosystem.


The Karner Blue butterfly belong in which group?
A
B
C
D
How can ADP be transformed into ATP?
Adding energy and a phosphate group
Removing energy and a phosphate group
Adding energy and another ribose
Removing adenine
Which statement is supported by the diagram?
The mitochondrion uses the sun’s energy directly.
The end products of photosynthesis do not provide energy for cellular respiration.
The main source of energy for photosynthesis is carbohydrates.
Carbohydrates are converted into ATP by the mitochondrion.
Which of the following is not a factor that affects photosynthesis?
Oxygen concentration
Water concentration
Light concentration
Carbon dioxide concentration
A potted plant is placed inside a clear, sealed vacuum container where no gases can get inside. The container has water pumped into it on a regular basis. The container is placed in the sun and the plant's growth is monitored. Which statement best describes what will most likely happen to the plant over time?
The plant will grow faster because it is sheltered from the wind.
The plant will die because it does not have oxygen for photosynthesis.
The plant will die because it does not have carbon dioxide for photosynthesis.
The plant will grow at a slow rate because it requires more water.
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?
Cells decompose more quickly under the most intense light.
Water evaporates from plants faster under the most intense light.
Gases in the leaves of plants expand most under the most intense light.
Photosynthesis occurs at the highest rate under the most intense light.
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?
Oxygen was produced by photosynthesis.
Carbon dioxide was removed by photosynthesis.
Carbon dioxide was produced by respiration.
Oxygen was removed by respiration.
Which of the following organism(s) performs cellular respiration?

a - mushroom
b - fern
c - animal
all of the above
What process releases energy from food molecules by producing ATP in the absence of oxygen?
Cellular respiration
Photosynthesis
Electron transport chain
Fermentation
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?
As the cells run out of oxygen, they switch to anaerobic respiration, which allows the cells to make small amounts of ATP in the absence of oxygen.
As the cells run out oxygen, they die off gradually and the weightlifter’s muscles have fewer contracting muscle cells.
The cells will never run out of oxygen if the weightlifter is breathing.
As the cells run out of oxygen, they will continue to make the same amount of ATP since oxygen is not required to make ATP.
Two different species of bacteria are examined. Scientists find that species X always produces CO2 and H2O during cellular respiration. Species Y always produces alcohol and CO2. Which conclusion can be made from these observations?
Only species Y is aerobic
Only species Y is anaerobic
Both species X and Y are aerobic
Both species X and Y are anaerobic
