Answer:
1. b. Dehydration synthesis
2. a. Hydrolysis
Explanation:
Hydrolysis is the process where water is used to break chemical bonds. Dehydration synthesis is the reverse reaction, where a bond is formed resulting in the loss of water from the molecule, so a water molecule is generated as a product.
That means that dehydration synthesis produces water, and hydrolysis uses water.

Answer:
Urey and miller cooked a "primordial soup" with Hadean gases, water and electricity to make <u>glucose</u>, <u>acetic acid</u>, <u>amino acids</u> and <u>lipids</u>.
Explanation:
In the Miller-Urey experiment, the aim was to reproduce the conditions of the earth before the existence of life, with the objective of demonstrating the formation of organic matter from inorganic molecules.
The scientists took water and gases present in the Hadean eon —previous to the existence of life— such as methane, carbon dioxide, hydrogen, nitrogen and even ammonia, the primordial soup. This mixture was subjected to electrical discharges, inside closed containers.
The results were some organic molecules, including glucose, acetic acid, amino acids and fatty acids. In these results the presence of macromolecules, such as proteins or nucleic acids, is not appreciated, however it was a significant contribution to the knowledge of the origin of life on earth.
If mitosis occurs correctly, the division of one cell by mitosis produces two cells.
