TEAS 7 Test Science Questions
2023
An organism with chloroplasts in its cells is probably. a.
a heterotroph
b. an autotroph
c. an herbivore
d. a primary consumer
{ANS} - B: Organisms that have chloroplasts in their cells carry on
photosynthesis and are therefore autotrophs. Autotrophs make their own food.
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
{ANS} - D: Water molecules are polar. Due to the fact that O2 draws the electrons
in the molecule toward itself.
The spaces between neurons are called?
a. synapses
b. dendrites
c. inter-neurons
d. cell gaps
{ANS} - 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.
Which Group of chemicals is not normally found in most living things? a.
carbohydrates
b. proteins
c. silicates
d. nucleic acids
{ANS} - C: Carbohydrates, proteins, and nucleic acids (RNA and DNA) are all very
important chemicals in living things.
The alimentary canal is associated with the? a.
spinal cord
b. digestive system
c. urinary tract
d. birth canal
{ANS} - B: The alimentary canal begins at the mouth and ends at the anus.
, 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
{ANS} - D: The villi are tiny projections in the
small intestine that increase the total
surface area of the intestine for
absorption of digested nutrients.
As light passes obliquely from air to water, it is bent. This bending is called?
a. diffraction
b. reflection
c. refraction
d. dispersion
{ANS} - C: Refraction is the bending of light as it passes obliquely from one medium
to another.
Which of the following organelles is not involved in protein synthesis? a.
ribsome
b. mitochondrion
c. rough endoplasmic reticulum
d. nucleus
{ANS} - D: The nucleus contains DNA. The ribosomes, located on the
rough endoplasmic reticulum, are the site for protein synthesis.
To be absorbed by cells, proteins must be changed to? a.
amino acids
b. sucrose
c. fatty acids
d. glycerol
{ANS} - A: Amino acids are the end products of protein digestion and are
small enough to be absorbed.
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
{ANS} - 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.
