Answer:
All
Explanation:
You would need carbon dioxide to be able to sustain life forms such as plants, warm enough temperatures to allow the development of animals, (because they cannot be frozen), they would, of course, need oxygen to allow anyone to breathe, and finally liquid water to sustain healthy life, because we must hydrate that is necessary for survival.

Answer:
The correct answer is 3. sugars
Explanation:
During photosynthesis, the light energy is captured by the chlorophyll and this energy is used in the formation of sugar molecules with the help of water. Oxygen is released as the byproduct of this process.
So the light energy which is captured is stored in the bonds of sugar and when this bond is broken down during oxidation the energy is released and converted into another form which is ATP and this ATP is called the energy currency of the cell. This ATP is used in many metabolic processes. Therefore the correct answer is sugar.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.
