ATI TEAS 7 Science Future Exam Questions & Answers
2026 | Latest Review Guide
1. Describe the characteristics that differentiate cardiac muscle from skeletal
and smooth muscle.
Cardiac muscle is striated, involuntary, and found only in the heart,
while skeletal muscle is striated and voluntary, and smooth muscle is
non-striated and involuntary.
Cardiac muscle is found in the limbs, while skeletal muscle is found in
the heart, and smooth muscle is found in the digestive tract.
Cardiac muscle is non-striated and voluntary, while skeletal muscle is
striated and involuntary, and smooth muscle is striated and voluntary.
Cardiac muscle is striated and voluntary, while skeletal muscle is non-
striated and involuntary, and smooth muscle is striated and involuntary.
2. Which hormone is specifically produced by the beta cells of the pancreas?
Insulin
Glucagon
Adrenaline
Cortisol
3. Which tissue type is characterized by being avascular and having a basement
membrane?
Nervous
Connective
Epithelial
Muscle
,4. Which group on the periodic table is known for typically losing two electrons
to form cations?
Group VIIA
Group IIA
Group VIA
Group IA
5. In a scenario where epithelial tissue is damaged, what role does the
basement membrane play in the healing process?
It serves as a scaffold for new epithelial cells to migrate and
proliferate during healing.
It prevents any further damage to the underlying tissues.
It directly stimulates the immune response to infection.
It enhances the blood supply to the damaged area.
6. If a patient has a condition that leads to excessive secretion of aldosterone,
what physiological effect might they experience?
Lower blood sugar levels
Decreased heart rate
Increased muscle mass
Increased blood pressure
7. Protein digestion in humans is primarily carried out by three enzymes. Pepsin
is found in the stomach (pH 2), where it aids in the breakdown of large
proteins into smaller peptides, while trypsin and chymotrypsin are found in
the small intestine (pH 8), where they aid in the further breakdown of the
proteins into amino acids and dipeptides that can be absorbed into the
, bloodstream. Graph 1 shows the effect of pH on the activity levels of the
three enzymes. Which of the following best predicts how the structure and
function of pepsin will change as it enters the small intestine?
Pepsin will not change in shape but may not work due to the basic
environment of the small intestine.
Pepsin will change in shape because of the basic environment of the
small intestine; therefore, its enzymatic activity will decrease.
Pepsin will not change in shape and will continue to break down
proteins in the small intestine.
Pepsin will change in shape because of the presence of trypsin and
chymotrypsin in the small intestine, both of which act as competitive
inhibitors.
8. If a patient has a deficiency in growth hormone, which gland is likely not
functioning properly, and what symptoms might they exhibit?
The pancreas; symptoms may include excessive thirst and frequent
urination.
The pituitary gland; symptoms may include stunted growth and
decreased muscle mass.
The thyroid gland; symptoms may include weight gain and fatigue.
The adrenal gland; symptoms may include increased stress and
anxiety.
9. If a scientist places dry ice in a vacuum chamber, what effect would this have
on the sublimation process of the dry ice?
The rate of sublimation would increase due to lower pressure in the
vacuum chamber.
The dry ice would not sublimate at all in a vacuum chamber.
, The dry ice would melt into liquid carbon dioxide before sublimating.
The rate of sublimation would decrease because of the lack of heat.
10. If a patient has a deficiency in B cells, what impact would this have on their
ability to fight infections?
They would have a reduced ability to produce antibodies.
They would have a heightened immune response.
They would be unable to produce T cells.
They would have an increased production of neutrophils.
11. Which hormone is NOT made by the anterior pituitary gland?
Prolactin
Growth Hormone
Oxytocin
Prohormone
12. Most of the fibers connecting the left and right cerebral hemispheres are
located in the
corticospinal tract
corpus callosum
hippocampus
cerebral ventricles
central canal
13. Which bone is specifically known as a sesamoid bone in the human body?
