Muscle cell activity increases and atp decreases below the set-point, a sensor molecule detects low atp and activates protein kinase a, protein kinase a activates protein kinase b, protein kinase b activates transporters that absorb glucose into the cell, glucose is metabolized. this is a:

Negative feedback mechanism

Explanation:

A negative feedback mechanism occurs when there is some change in the homeostatic conditions of the body. These changes are sensed as stimuli and the desired response is generated to oppose the change and to restore the original condition. In the given example, the reduced levels of ATP in muscle cells during increased muscular activity are sensed as a stimulus. The body restores the ATP levels by stimulating the absorption and metabolism of glucose by the cell. Therefore, it represents a negative feedback mechanism.

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
