They formed from a cloud of dust and gas.
Explanation:
A nebula is where the formation of stars takes place, so the Nebula Theory would pertain to the planets forming in the same way.

Answer:
Hypothalamic-pituitary-adrenal axis (HPA axis)
Explanation:
- The three-stage process describing the physiological changes that take place in the body when it is under stress is known as general adaptation syndrome (GAS).
- The model describing the three-stage process was given by the scientist Hans Selye.
- According to this model, the responses in the body that occur during stress is regulated by the Hypothalamic-pituitary-adrenal axis (HPA axis) where the brain senses the stress and then the signals travel from the hypothalamus to the pituitary and finally the body releases cortisol from adrenal glands that contributes to the various changes.
If you choices are the following;
a. use and store O2.
b. use and make ATP.
c. store energy in glucose.
d. release energy from glucose.
The answer would be b. use and make ATP.
Both processes use and make ATP but the way they do this are reversed. In cellular respiration, ATP is made by breaking down complex molecules. Photosynthesis on the other hand uses ATP to produce complex molecules.
