yard

300

Animals/insects can float or walk on water because water is highly attracted to itself. This phenomena is called ____________.

surface tension

300

Identify the basic shape of carbohydrates and lipids

Carbohydrates - circular (hexagon - sugar molecules)

Lipids - linear (glycerol and triglycerides)

300

Identify the macromolecule


Protein (notice the Nitrogen)

300

Enzymes are a type of which macromolecule?

Proteins

400

Why do we study chemistry in biology?

Answer must mention at least one component:

Chemistry explains/describes reactions, bonds, and chemicals/elements living organisms require for life

400

Explain why aquatic life can exist when the atmosphere is below freezing?

Water becomes less dense as ice and floats above water. This creates an ice-layer that insulates the water below.

Identify the macromolecule:


Nucleic Acid (notice the P and N)
