Answer:

How does cellular respiration work in animals?

When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration. Cellular respiration occurs in the individual cells. Digested foods have chemical energy stored in them.

1) carbon dioxide I think hope it helps

What are two ways in which cells use the energy temporarily stored in ATP?

Answers

Answer: Energy provided by ATP is used in active transport, to contract muscles, to make proteins, and in many other ways

The two main ways in which cells use the energy temporarily stored in the form of ATP is in active transport, and to make proteins.

What is Active transport?

Active transport is the movement of molecules, ions, solutes, solvents against the concentration gradient. The flow of material takes place from the region of their lower concentration to the region of their higher concentration. The transport is against the gradient and hence requires energy to proceed which is given by ATP.

ATP is required to synthesize proteins in the ribosomes of the cell through the process of translation. This is a highly energy-consuming energy and thus required large amount of ATP.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?

Answers

Answer:

A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.

Explanation:

Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.

The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.

Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
