Which reaction is responsible for the production of lipids when glycerol is joined to three fatty acids?
Anna35 [415]

This reaction is called a condensation reaction. It is also known as  a dehydration reaction.

When three fatty acids become attached to a glycerol molecule, a triglyceride is formed.  The fatty acids become attached to the glycerol through a condensation reaction named so because 3 water molecules are formed from the 3 OH groups from the fatty acid chains and 3 H atoms from the glycerol.

The bond formed between the fatty acid chain and the glycerol is called an ester linkage.

The expected ratio of phenotypes among the progeny of a test cross is 1:1:1:1. Out of 200 total resulting progeny, 48 occur in o
Rzqust [24]

Answer: The progeny of this cross do not conform to a 1:1:1:1 ratio

Explanation: This is because out of the 200 total resulting progeny, we must have 50 in each phenotype class to conform with the 1:1:1:1 which is not so as we have 48 in one of the phenotypic class already. Therefore, it did not conform to the ratio.

Answer:

The answer to these questions are the following:

1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter

2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter

Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:

1. In a hypotonic solution, the cells will become turgid  

2. In an isotonic solution, the cells will become flaccid.  

3. In a hypertonic solution, the cells will shrink (plasmolysis)

When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss

When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.
