Question

1. molecule

a. stores energy and provides structure to cells.

1. ion

b. stores energy and forms the core of cell membranes

1. cells

c. charged atom formed by gaining or losing electrons

1. organic

d. material of which living organisms are made; contains carbon
compound
backbone.

1. protein

e. what all living organisms are composed of (exhibit what we call life)

1. carbohydrate

f. composed of chains of amino acids that perform cell functions

1. lipid

g. a pair or group of atoms that can exist as a single unit

Explanation:

• Molecule: A pair or group of atoms that can exist as a single unit. This is the basic definition of a molecule.
• Ion: Charged atom formed by gaining or losing electrons. Ions are atoms with an electrical charge due to electron gain or loss.
• Cells: What all living organisms are composed of (exhibit what we call life). Cells are the fundamental units of life.
• Organic Compound: Material of which living organisms are made; contains carbon backbone. Organic compounds are characterized by a carbon - based structure.
• Protein: Composed of chains of amino acids that perform cell functions. Proteins are essential for various cellular processes.
• Carbohydrate: Stores energy and provides structure to cells. Carbohydrates serve as an energy source and contribute to cell structure.
• Lipid: Stores energy and forms the core of cell membranes. Lipids play a crucial role in energy storage and membrane formation.
