1. Organisms in just large molecules like carbohydrates proteins and fats and convert them into small molecules like carbon dioxide and water.
2. During cellular respiration of glucose molecule is gradually broken down into carbon dioxide and water. Then some ATP is produced directly in the reactance that transformers glucose.
3. Photosynthesis converts carbon dioxide and water into oxygen and glucose. While, cellular respiration converts oxygen and glucose into water and carbon dioxide.

Which statement describes the water gas particles in the air above the cup compared with the water liquid

Law Incorporation [45]

Answer:

The particles move faster and are far apart

Explanation:

A substance may exist in three states of matter; solid, liquid and gas.

In the solid state, there is very strong intermolecular forces between the particles of the substance. They can only vibrate or rotate about their mean positions but can not translate.

In the liquid state, the particles of the substance have a greater degree of freedom than in the solid. The magnitude of intermolecular forces is lower than in solids, the molecules can move at low speeds.

In a gas, the molecules are separated from each other with negligible intermolecular interaction hence they move at very high speed.

Therefore, for the water gas particles in the air above the cup; the particles move faster and are far apart.

________ are molecules whose general structure includes a central carbon with a carboxyl group, an amine group, a hydrogen molec

IgorLugansk [536]

The amino acids are the molecules where we can found the carboxyl group (- $COO^{-}$ ), amino group (- $NH_{2}$ ), hydrogen atom (H) and a residual R-group. On the structure of the residual R-group the name of the amino acid depends. Like if R is hydrogen (H) the amino acid is alanine; If R- group is a phenyl group i.e. $-C_{6}H_{5}$ , the compound is called phenyl alanine. The structure of the general amino acid skeleton can be shown as-
