hich statement describes a plant tropism?

Answer options with 5 options
A.
The plant died for lack of nutrients in the soil.

B.
Chlorophyll is contained in the leaves.

C.
The plant's roots grew in the direction of water.

D.
The plant could reproduce itself by either seeds or runners.

E.
The plant dropped its leaves in the fall.

C. The plant's roots grew in the direction of water.

The correct answer is A. glycerol.

To determine which molecule is a main component of fatty acids, we need to understand the structure of fatty acids and their composition.

Fatty acids are long-chain hydrocarbon molecules consisting of a carboxylic acid group (-COOH) at one end and a methyl group (-CH3) at the other end. The main component of fatty acids is a hydrocarbon chain, commonly referred to as the fatty acid chain.

The correct answer among the given options is A. glycerol. Glycerol is not a component of fatty acids but rather a component of triglycerides, which are made up of three fatty acids attached to a glycerol molecule. However, fatty acids themselves consist of a hydrocarbon chain, as previously mentioned.

Option B, glucose, is a monosaccharide and is not a component of fatty acids. Glucose is the principal source of energy in the body and is used to make complex carbohydrates.

Option C, ribose, is a pentose sugar and a component of RNA (ribonucleic acid) but is not present in fatty acids.

Option D, peptide, refers to the bonds formed between amino acids in proteins and is not a component of fatty acids.

Therefore, the correct answer is A. glycerol, which is a component of triglycerides but not a component of fatty acids themselves.
