ATI TEAS HUMAN BIOLOGY EXAM 2025 | 70
QUESTIONS WITH ACCURATE SOLUTIONS
,1. Which of the following is a substance that the kidneys remove from the
blood during filtration?
Salts
Oxygen
Carbon Dioxide
Red Blood Cells
2. Two researchers note that when Weeds A and B grow next to each other,
the roots of Weed A stop growing when they enter the root zone of Weed
B. Since activated charcoal is known to absorb organic compounds, the
researchers apply activated charcoal to the soil around Weed B. They note
that the roots of Weed A then grow into the root zone of Weed B. Which of
the following hypotheses is being tested by the addition of activated
charcoal to the soil?
Weed A absorbs activated charcoal, which enhances root growth
for Weed A.
Weed B grows best in soil that contains few organic compounds.
Weed A is attracted to soil that contains activated charcoal.
Weed B produces an organic compound that inhibits root growth
for Weed A.
3. Which of the following arteries has the primary responsibility of supplying
blood to the reproductive system?
Common iliac artery
Gonadal artery
Inguinal artery
Femoral artery
, 4. If a patient with Type I diabetes does not receive insulin therapy, what
physiological changes might occur in their body, and how would this affect
their overall health?
Increased insulin levels leading to hypoglycemia and potential
coma.
Elevated blood glucose levels resulting in ketoacidosis and long-
term complications.
Decreased metabolism causing weight gain and lethargy.
Enhanced muscle growth due to lack of insulin.
5. Explain how the structure of villi and microvilli contributes to their function
in nutrient absorption.
Their flat shape allows for easier movement of food.
Their extensive surface area allows for more efficient nutrient
uptake.
Their rigid structure prevents the loss of nutrients.
Their length helps in the mechanical breakdown of food.
6. What is the primary function of lysosomes in human cells?
Protein synthesis
Energy production
Digestion of waste materials
DNA replication
7. A zygote contains ________ chromosomes in normal circumstances.
