Can you guys me i have a test tomorrow

11. b.

Explanation:

Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Write out the equations:

Photosynthesis

carbon dioxide + water + light energy => oxygen + glucose/sugar

CO₂ + H₂O + light => O₂ + C₆H₁₂O₆

The carbohydrate is stored in the plant until it needs it, like to perform cellular respiration.

Cellular Respiration

oxygen + glucose/sugar => carbon dioxide + water + ATP energy

O₂ + C₆H₁₂O₆ => CO₂ + H₂O + ATP

The carbohydrate is used to make energy. Energy is released from carbohydrates.

Glucose, C₆H₁₂O₆, is a carbohydrate.

Fault in other options:

a. Photosynthesis and cellular respiration both occur in plants. Plants have mitochondria for cellular respiration.

c. Photosynthesis uses carbon dioxide and cellular respiration releases carbon dioxide.

d. Photosynthesis uses carbon dioxide, cellular respiration uses oxygen.

when a reversible reaction is occurring in both directions at the same rate; the products and reactants do not change in concentration. a chemical reaction where the compound is broken into its constituent parts.

explanation:

mark brainliest and have a great day!

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
