Q #1: The "gray matter of the brain is largely made up of which of the following?

A. Neuron cell bodies

B. Meninges

C. Neuron cell axons

D. Corpus callosum

Answer Explanation

The gray matter of the brain primarily consists of neuron cell bodies, along with dendrites, glial cells, and unmyelinated axons. It appears gray because it lacks the white fatty myelin sheath that covers many nerve fibers.
Q #2: Which of the following would result in an increase in the chemical reaction?

A. Adding more of the product

B. Decreasing the concentration of the reactant

C. Sealing the reaction in an airtight container

D. Using a mortar and pestle to grind a solid reactant to a powder

Answer Explanation

Crushing a solid reactant into powder increases the surface area of the reactant, thereby increasing chemical reaction. This is because more of the reacting molecules or ions are exposed to the other reactant, which increases the chance of particles colliding and leads to more successful collisions per second.
Q #3: Which of the following body systems breaks down proteins into amino acids?

A. Digestive

B. Excretory

C. Circulatory

D. Endocrine

Answer Explanation

The digestive system breaks down complex food substances into small and less complex absorbable compounds. Proteins, for instance, are broken down to constituent amino acids through a digestion process that combines mastication and enzymatic breakdown.
