In the early twentieth century, kudzu (an Asian vine) was planted to help control erosion in southeastern states. Presently, kudzu is expanding at a rate of more than 120,000 acres per year. As kudzu spreads, it dominates ecosystems, choking out trees and other plants. Which choice correctly identifies kudzu’s role in an ecosystem?
A. invasive species
B. diversified species
C. indigenous species
D. carnivorous species.
A. invasive species

Cellular respiration is the process that allows living organisms to extract energy from nutrients. What is the main difference between aerobic and anaerobic respiration?
A. Aerobic respiration uses oxygen, while anaerobic respiration does not.
B. Anaerobic respiration uses oxygen, while aerobic respiration does not.
C. Aerobic respiration produces carbon dioxide, while anaerobic respiration does not.
D. Anaerobic respiration produces carbon dioxide, while aerobic respiration does not.
A. Aerobic respiration uses oxygen, while anaerobic respiration does not.

Shante wants to increase the yield of her herb garden. A friend suggests that she pinch off the tops of the plants as they grow. By cutting off the apical meristem, how should this increase yield?
A. Photosynthesis takes place in the chloroplasts of green plant cells.
B. Meristems are areas where cell division is very active, so trimming here will increase growth because of the release of axins, or growth hormones.
C. The plant will not grow taller because pinching the tops will kill the plant.
D. The apical meristem uses ATP as its energy source.
A. Photosynthesis takes place in the chloroplasts of green plant cells.

The leaf cells of green plants usually contain chloroplasts. The root cells of green plants do not usually contain these structures, or contain fewer of them. Which statement best explains why?
A. Root cells eject organelles to make space for water and nutrients to pass through the roots.
B. Root cells are simpler and do not need energy to perform their specialized functions.
C. Leaf cells are large enough to contain chloroplasts, but root cells are not.

Sam places a leaf of a plant in a bottle containing potassium hydroxide. He can periodically analyze the gas inside the flask. He places the plant outside in direct sunlight, and collects and analyzes the gas in the bottle in comparison to that of the plant. He notices that the carbon dioxide levels are very low inside the bottle. What can he infer about potassium hydroxide?
A. It absorbs carbon dioxide.
B. It releases oxygen.
C. It produces water.
D. It dissolves cells.
A. It absorbs carbon dioxide.

Zooxanthellae are photosynthetic protozoa that live in coral reefs. These corals get most of their energy from carbon compounds made by the zooxanthellae. When ocean waters rise by 1–2°C, the change can shock cells in the corals into releasing zooxanthellae. Coral die from the change. Which of these limiting factors most directly affects the organisms in this relationship?
F. temperature
G. photosynthesis
H. the amount of space
I. the population of corals
F. temperature

C. Photosynthesis uses glucose and carbon dioxide to make water and oxygen; respiration uses glucose and oxygen to make water and carbon dioxide.
