Test Bank for Biology Concepts EXAM Questions AND Correct Answers
Adhesion - ✔✔ The property of water that allows molecules to stick together.
Cohesion - ✔✔ The property of water that allows it to stick to other substances.
Dehydration synthesis - ✔✔ A process that joins monomers together by removing water.
Dehydration synthesis example - ✔✔ During dehydration synthesis, monomers are joined
to form polymers, such as when glucose molecules join to form starch.
Density of water - ✔✔ Water is more dense as a liquid than as a solid.
Four main types of organic molecules - ✔✔ Carbohydrates, lipids, proteins, and nucleic
acids.
High heat capacity - ✔✔ A property of water that means it heats up and cools down
slowly.
Hydrogen bonds - ✔✔ Weak bonds that are generally weaker than covalent bonds.
Ionic bond - ✔✔ A type of bond that involves one atom taking an electron from another
atom.
Ionic bond vs Covalent bond - ✔✔ An ionic bond involves the transfer of electrons, while
a covalent bond involves the sharing of electrons.
Levels of protein structure - ✔✔ The four levels of protein structure are primary,
secondary, tertiary, and quaternary, differing in complexity and organization.
Lipid molecule structure - ✔✔ A lipid molecule contains one glycerol and three fatty acids.
