Section I: Science
Number of Questions: 35
Topics: Human Anatomy & Physiology, Biology, Chemistry, Scientific Reasoning
1. Which of the following is the primary function of the nucleus?
a) ATP production
b) Protein synthesis
c) Storage of genetic material
d) Lipid metabolism
Answer: c) Storage of genetic material
Rationale: The nucleus houses the cell's DNA and controls cellular activities by regulating
gene expression.
2. Which of the following blood cells is primarily responsible for immune defense
against pathogens?
a) Erythrocytes
b) Platelets
c) Leukocytes
d) Thrombocytes
Answer: c) Leukocytes
Rationale: Leukocytes (white blood cells) are key components of the immune system that
identify and eliminate pathogens.
3. A solution with a pH of 10 is classified as:
a) Strong acid
b) Weak acid
c) Neutral
d) Base
Answer: d) Base
Rationale: A pH above 7 is basic or alkaline. A pH of 10 indicates a base.

4. Which of the following structures is part of the peripheral nervous system?
a) Brain
b) Spinal cord
c) Cranial nerves
d) Cerebellum
Answer: c) Cranial nerves
Rationale: Cranial nerves and spinal nerves constitute the peripheral nervous system, while
the brain and spinal cord form the central nervous system.
5. Which of the following describes active transport?
a) Movement of water across a membrane
b) Movement of molecules from high to low concentration
c) Movement of substances against a concentration gradient using energy
d) Diffusion of oxygen into cells
Answer: c) Movement of substances against a concentration gradient using energy
Rationale: Active transport requires ATP energy to move molecules against their
concentration gradient, such as the sodium-potassium pump.
6. Which hormone is produced by the adrenal medulla and is involved in the fight-or-
flight response?
a) Cortisol
b) Aldosterone
c) Epinephrine
d) Insulin
Answer: c) Epinephrine
Rationale: Epinephrine (adrenaline) is released by the adrenal medulla during stress,
increasing heart rate and blood flow to muscles.
7. Which of the following is a function of the kidneys?
a) Production of bile
b) Regulation of blood pH
c) Digestion of carbohydrates
, ATI TEAS 7 Comprehensive Predictor Test Bank 2026
d) Absorption of nutrients
Answer: b) Regulation of blood pH
Rationale: The kidneys maintain acid-base balance by excreting hydrogen ions and
reabsorbing bicarbonate.
8. In a scientific experiment, the group that receives the treatment being tested is
called the:
a) Control group
b) Experimental group
c) Constant group
d) Placebo group
Answer: b) Experimental group
Rationale: The experimental group is exposed to the independent variable being tested,
while the control group is not.
9. Which of the following correctly orders the levels of organization from most
complex to simplest?
a) Cell, tissue, organ, organ system, organism
b) Organism, organ system, organ, tissue, cell
c) Tissue, cell, organ system, organism, organ
d) Organ, tissue, cell, organism, organ system
Answer: b) Organism, organ system, organ, tissue, cell
Rationale: This sequence moves from the highest level of organization (organism) down to
the simplest (cell).
10. Which of the following is the function of the bronchioles in the respiratory
system?
a) Gas exchange
b) Production of mucus
c) Transport of air to the alveoli
d) Filtration of dust particles
Answer: c) Transport of air to the alveoli
