Which Group of chemicals is not normally found in most living things? a. carbohydrates
b. proteins c. silicates
d. nucleic acids
Correct Ans - C: Carbohydrates, proteins, and nucleic acids (RNA and DNA) are all very important chemicals in living things.
The alimentary canal is associated wit...
An organism with chloroplasts in its cells is probably.
a. a heterotroph
b. an autotroph
c. an herbivore
d. a primary consumer
Correct 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
Correct 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
Correct 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.

The alimentary canal is associated with the?
a. spinal cord
b. digestive system
c. urinary tract
d. birth canal
Correct 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
, Correct 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
Correct 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
Correct 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
Correct 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
Correct 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.
Which group of organisms help prevent the accumulation of organic wastes in
nature?
a. rabbits
b. mosses
c. bacteria
d. ferns
Correct Ans - 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
d. lower in pitch
, Correct Ans - 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
Correct Ans - 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
Correct Ans - 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
Correct Ans - 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
Correct Ans - 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.
A reading on the Celsius scale is 5. On the Fahrenheit scale, the reading would be
closet to?
a. 225
b. 30
c. 40
d. 95
Correct Ans - C: the formula for converting temperature in Celsius to temperature
in Fahrenheit is: T Fahrenheit = 9/5 x T Celsius + 32, therefore 5 degrees Celsius
convert to 41 degrees Fahrenheit. 9/5 x 5 = 9
