[Q] Epilepsy and splay leg are located on the same what?
Options:
- (A) organ
- (B) Joules
- (C) kalenchoes
- (D) sensory neurons
- (E) chromosome
- (F) nerves
- (G) critical organs
- (H) four limbs
[A] Here's my solution: Genes that are located on the same chromosome are called linked genes. For example, epilepsy and splay leg tend to link with the vienna white gene. Epilepsy and splay leg are located on the same chromosome. The answer is (E).

[Q] How do animals dissipate body heat?
Options:
- (A) sweat
- (B) eat food
- (C) lay in the sun
- (D) insulation
- (E) coat
- (F) osmosis
- (G) fur
- (H) cooling
[A] Here's my solution: Evaporation of sweat uses energy, and the energy comes from body heat. Animals are inefficient energy converters. Animals produce body heat which is dissipated by sweat. The answer is (A).

[Q] When substances react with one another the sharing or transfer of what occurs?
Options:
- (A) Energy.
- (B) voltage
- (C) heat produced
- (D) heat energy
- (E) electrons
- (F) a solute
- (G) kinetic
- (H) Energy
[A] Here's my solution: Chemical bonds form when substances react with one another. Chemical Bonding A chemical bond is the sharing or transfer of electrons. The sharing of transfer of electrons happens when substances react with one another. The answer is (E).

[Q] In what way do viruses not proliferate?
Options:
- (A) adding heat
- (B) at or near the margins
- (C) They may not survive.
- (D) dry conditions
- (E) heat or cold
- (F) by indirect light
- (G) Localized damage
- (H) binary division
[A]
Here's my solution: Populations of viruses do not grow through cell division because they are not cells. Cells, the basic units of every living organism, proliferate by binary division. Viruses do not proliferate via binary division. The answer is (H).
