TEAS Test Science Questions and
Answers 2021/2022.
1. An organism with chloroplasts in its cells is probably.
a. a heterotroph
b. an autotroph
c. an herbivore
d. a primary consumer Correct Answer - B: Organisms that have chloroplasts in their
cells carry on photosynthesis and are therefore autotrophs. Autotrophs make their
own food.
2. What property of water allows someone to fill a glass slightly above the rim without the water
flowing over?
a. specific gravity
b. capillarity
c. opacity
d. surface tension Correct Answer - D: Water molecules are polar. Due to the fact that
O2 draws the electrons in the molecule toward itself.
3. The spaces between neurons are called?
a. synapses
b. dendrites
c. inter-neurons
d. cell gaps Correct Answer - A: An impulse travels down the axon of a neuron and
reaches the terminus. There, chemicals are released in response, which travel across
the synapse to the next neuron. Thus the impulse is transmitted to the next neuron.
4. Which Group of chemicals is not normally found in most living things?
a. carbohydrates
b. proteins
c. silicates
d. nucleic acids Correct Answer - C: Carbohydrates, proteins, and nucleic acids (RNA
and DNA) are all very important chemicals in living things.
5. The alimentary canal is associated with the?
a. spinal cord
b. digestive system
c. urinary tract

d. birth canal Correct Answer - B: The alimentary canal begins at the mouth and
ends at the anus.
6. The numerous villi in the small intestine serve to?
a. secrete enzymes for digestion
b. absorb water from dissolved foods
c. secrete hydrochloric acid to dissolve food
d. provide greater surface for absorption Correct Answer - D: The villi are tiny
projections in the small intestine that increase the total surface area of the intestine
for absorption of digested nutrients.
7. As light passes obliquely from air to water, it is bent. This bending is called?
a. diffraction
b. reflection
c. refraction
d. dispersion Correct Answer - C: Refraction is the bending of light as it passes
obliquely from one medium to another.
8. Which of the following organelles is not involved in protein synthesis?
a. ribsome
b. mitochondrion
c. rough endoplasmic reticulum
d. nucleus Correct Answer - D: The nucleus contains DNA. The ribosomes, located on
the rough endoplasmic reticulum, are the site for protein synthesis.
9. To be absorbed by cells, proteins must be changed to?
a. amino acids
b. sucrose
c. fatty acids
d. glycerol Correct Answer - A: Amino acids are the end products of protein digestion
and are small enough to be absorbed.
10. A neuron that transmits impulses from the receptors to the spinal cord is called?
a. motor neuron
b. an associative neuron
c. an interneuron
d. a sensory neuron Correct Answer - D: A sensory neuron conveys a message from a
sensory organ to the spinal cord, which transmits the message via a motor neuron
to the effector muscle.
11. Which group of organisms help prevent the accumulation of organic wastes in nature?
a. rabbits
