100

This is the smallest unit that can carry out all life functions.

What is a cell?

100

This weak interaction holds water molecules together.

What is a hydrogen bond?

100

This element forms the backbone of organic molecules.

What is carbon?

100

Proteins are made of these monomers.

What are amino acids?

100

This macromolecule is used for short-term energy storage.

What are carbohydrates?

200

his term refers to the ability of an organism to maintain stable internal conditions.

What is homeostasis?

200

A solution with pH 2 is best described as this.

What is acidic?

200

This functional group is found in alcohols and is polar.

What is a hydroxyl group (-OH)?

200

What are amino acids?

What is a peptide bond?

200

The monomer of nucleic acids is this.

What is a nucleotide?

300

This level of biological organization includes tissues working together.

What is an organ?

300

This property of water helps stabilize temperature in organisms.

What is high specific heat?

300

This functional group can act as an acid by donating H⁺.

What is a carboxyl group (-COOH)?

300

This level of protein structure is the amino acid sequence.

What is primary structure?

300

This bond links monosaccharides together.

What is a glycosidic bond?

400

This is a testable explanation for natural phenomena.

What is a hypothesis?

400

This term describes a substance that resists changes in pH.

What is a buffer?

400

This functional group is found in amino acids and acts as a base.

What is an amino group (-NH₂)?

400

Alpha helices and beta sheets are part of this level of structure.

What is secondary structure?

400

This macromolecule makes up cell membranes.

What are lipids?

500

This type of molecule speeds up chemical reactions without being consumed.

What is an enzyme?

500

This occurs when water molecules surround and dissolve ionic or polar compounds.

What is hydration shell formation? (or solvation)

500

This type of molecule avoids water and is usually nonpolar.

What is a hydrophobic molecule?

500

Heat causing a protein to lose its shape is called this.

What is denaturation?

500

DNA and RNA are examples of this macromolecule class.

What are nucleic acids?
