An organism with chloroplasts in its cells is probably.
a. a heterotroph
b. an autotroph
c. an herbivore
d. a primary consumer - 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 - 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 - 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 - 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 - 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
,TEAS Test Science Questions and
answers. 24 pages, Rated A
d. provide greater surface for absorption - 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 - 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 - 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 - 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 - 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.
Which group of organisms help prevent the accumulation of organic wastes in nature?
a. rabbits
b. mosses
c. bacteria
d. ferns - C: Bacteria comprise the decomposer portion of the food chain.
As the eardrum is made to vibrate more rapidly, the sound is perceived as?
a. louder in intensity
b. softer in intensity
c. higher in pitch
, TEAS Test Science Questions and
answers. 24 pages, Rated A
d. lower in pitch - C: High-pitch sounds are heard when the receptor cells closer to the
oval window are stimulated, and low-pitch sounds result from the stimulation of the cells
that are farther down the cochlea.
In a field of pure white asters, a grower noticed a single blue aster. How could the
grower test whether this change affected the gamete-producing cells of the plant?
a. self-pollinate the flower, and plant the resulting seeds
b. examine the blue petals under an electron microscope
c. preform a chemical analysis to find the nature of the blue pigment
d. preform vegetative propagation on a cutting of the plant - A: Remember that during a
phase change from liquid to gas the temperature remains constant at 100C.
A human egg will develop into a female if it is fertilized by sperm containing?
a. an X chromosome
b. a Y chromosome
c. an XY chromosome
d. an XXY chromosome - A: A female has two X chromosomes, and a male has one X
chromosome and one Y chromosome. For a human egg to develop into a female, it
must be fertilized by a sperm containing an X chromosome.
In a food chain involving grass, grasshoppers, birds and mammals, the orginal source of
energy is?
a. glucose
b. sunlight
c. chlorophyll
d. ATP - B: Sunlight is absorbed by the chlorophyll contained in plants. The absorbed
energy fuels photosynthesis which produces glucose. In this food chain, grass is the
producer.
Which of the following equations represents a neutralization reaction?
a. 2Na+MgCl2 > Mg+2NaCl
b. CaCO3+4C > 3CO+CaC2
c. 4NH3+5O2 > 6H2O+4NO
d. H2CO3+Ca(OH)2 > 2H2O+CaCO3 - D: Equation d is a reaction between an acid
(carbonic acid) and a base [(Ca(OH)2] to form water and a salt. It is the only
neutralization reaction among the choices.
