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?

- 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
- 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

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

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

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?
