Answer:
mechanical weathering:
ice wedging: does not change rocks composition: abrasion
chemical weathering:
oxidation: changes rocks composition: acid rain
The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.
Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;
- Protection of vital organs
- Insulating the body from cold
- Serving as an energy store
In times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.
As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15 Ibs of weight.

ATP is broken down to ADP and Pi when energy is required to carry out the metabolic process. ATP is also released during the metabolic process.
<u>Explanation:</u>
The pumping of hydrogen ions across the inner membrane creates concentration gradient where there is higher concentration of the ions in the intermembrane space than in the matrix. This chemiosmotic gradient causes the ions to flow back across the membrane into the matrix, where their concentration is lower.
ATP synthase behaves as a channel protein thereby helping the hydrogen ions cross the membrane. It also has the ability to act as an enzyme, forming ATP from ADP and inorganic phosphate.
After passing through the electron transport chain, the used electrons joins with oxygen to form water. That is why oxygen is required. In the absence of oxygen, this process will not occur.
It is the second step in the scientific method, where you ask a question and propose a hypothesis to be answered through a series of scientific tests.
