LE Ch9 Q2

Which life process carried out by a green plant is represented in the diagram below?

• respiration

• photosynthesis

• digestion

• replication

Base your answer to the question on the information and diagram below and on your knowledge of biology. The diagram represents a cell. Which structure is responsible for the synthesis of ATP?

• a

• b

• c

• d

Autotrophs differ from heterotrophs in that only autotrophs

• require carbon dioxide for cellular respiration

• release oxygen as a product of cellular respiration

• synthesize nutrients using carbon dioxide and water

• break down sugars to assemble other molecules

The diagram below represents two cells viewed using the same magnification with the same microscope. One possible conclusion that can be drawn about the activity of these two cells is that

• more active transport occurs in cell B than in cell A

• more active transport occurs in cell A than in cell B

• cell B uses some of the extra mitochondria to make food

• cell A is a plant cell since it has a cell wall

A news release about production of farmraised salmon contains the following information:

-The program is mating targeted fish to concentrate key traits in Atlantic salmon stocks.

-The three-year process includes spawning, tagging, and choice of parent fish.

-The fish are weighed, measured, and monitored to identify those with the best growth rates.

-The project examines the performance of fish to determine which fish to use to produce the next generation.

These statements indicate that the producers are attempting to improve salmon through the use of

• genetic engineering

• homeostatic feedback

• selective breeding

• natural selection

The chart below lists substances involved in the process of photosynthesis. Which statement best describes how these substances interact in photosynthesis?

• A and B combine to produce C and D.

• B and C combine to produce A and D.

• C and D combine to produce A and B.

• A and C combine to produce B and D.

The diagram below represents two processes that occur in organisms. A characteristic represented by X is common to both of these processes. A characteristic that the two processes have in common is that each process

• uses ATP

• requires enzymes

• uses oxygen

• moves molecules

Autotrophs might survive when heterotrophs cannot, because autotrophs are able to

• reproduce asexually

• become dormant

• exist without respiration

• make their own food

Base your answer to the question on the diagram below and on your knowledge of biology. What information would be appropriate to add to box X in order to complete the diagram?

• cellular respiration by humans

• simple sugar

• oxygen

• burned by automobiles

Why is the kitchen in the photo a good environment for growing healthy plants? (Choose the best answer.)

• The ovens will provide heat for the plants.

• The sink will provide water for watering.

• There is a lot of counter space for placement

• There are many windows to provide sunlight.
