Question

1. according to the law of conservation of energy, when energy appears to be lost, it actually:

a) becomes mass
b) transforms into a less useful form like heat
c) disappears completely
d) turns into potential energy permanently

1. which statement correctly connects photosynthesis and respiration?

a) photosynthesis stores energy; respiration releases it.
b) respiration stores sunlight energy; photosynthesis releases atp.
c) both create energy from nothing.
d) both occur only in plant cells.

Explanation:

Step1: Analyze question 9

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed. Heat is a common form of less - useful energy.

Step2: Analyze question 10

Photosynthesis uses sunlight to store energy in glucose. Respiration breaks down glucose to release energy.

Answer:

1. B. Transforms into a less useful form like heat
2. A. Photosynthesis stores energy; respiration releases it.
