Back

True.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms, typically between nonmetals.

Front

What are the four main types of biological macromolecules?

Back

Carbohydrates, Proteins, Lipids, and Nucleic Acids.

Front

Define carbohydrates.

Back

Carbohydrates are organic compounds made of carbon, hydrogen, and oxygen, typically in a ratio of 1:2:1, and are a primary source of energy.

Front

What is the function of lipids in biological systems?

Back

Lipids store energy, provide insulation, and make up cell membranes.

Front

What is the pH scale?

Back

The pH scale measures the acidity or basicity of a solution, ranging from 0 (acidic) to 14 (basic), with 7 being neutral.
