Answer:
11. b.
Explanation:
Photosynthesis stores energy in carbohydrates, cellular respiration releases energy from carbohydrates.
Glucose, C₆H₁₂O₆, is a carbohydrate.
Write out the equations:
<u>Photosynthesis</u>
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.
<u>Cellular Respiration</u>
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.
Answer:C. It carries cold water from the equator to the poles.
D. It wears away rock and soil.
E. It reflects sunlight that hits the oceans.

Answer:
Explanation:
The distance to the Sun is 5,890,000,000,000. We need to write this distance in km.
A number can be written as in scientific notation where x is a real no and y is any integer.
There are 10 zeros in the given number and also there are 12 digits after. It would mean that,
So, the distance in scientific notation is :
