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

300
Identify the macromolecule
Protein (notice the Nitrogen)
300

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

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.
