Answer:
A or/and D
Explanation:
Environmental science is the study of how organisms interact with their environment so it can be either a or d. I would say a combination of both.
The molecule of water is different from the molecules of oxygen and hydrogen in the following ways:
1. Combustion: Oxygen supports combustion, hydrogen burns in the air to form water. Water is not combustible. It rather inhibits combustion when poured over burning substances.
2. State of matter: Water is a liquid in room temperature whereas oxygen and hydrogen are gases. The polar nature of water contributes to hydrogen bonding between the hydrogen and oxygen atoms of water.
3. Density: Water is denser than both oxygen and hydrogen. Hydrogen bonding helps pack more molecules of water in less space.
4. Freezing point: Water freezes to ice at 0°C whereas oxygen freezes at -218°C and hydrogen freezes at -259°C.

Answer:
They have approximately similar molecular weight, chemical composition and solubility.
Explanation:
Macro molecules are bigger molecules having more weight. The molecular weight of the macro molecules is more than 10,000 Dalton. They are chiefly the carbohydrates, proteins, lipids, and nucleotide. These are found in the acid-insoluble pool. This means all macro-molecules are acid insoluble. They are all polymers. Their composition is similar, having carbon and hydrogen which forms bonds with other compounds like nitrogen, sulphur, phosphate, OH, etc. They are all basic components of the cell and cell membrane and all are organic molecules.
