112
Q

What is not a fruit?

A

Potato Fruits have seeds. Tomatoes, cucumbers, and green peppers have seeds. A potato is a tuber.

113
Q

A

in the ear. The hammer, anvil, and stirrup are the three tiny bones that connect the eardrum with the inner ear.

114
Q

A condition not associated with heavy cigarette smoking is

A

slowing of the heartbeat. Cigarette smoking can speed up the heartbeat.

115
Q

You are most likely to develop hypothermia when

A

it is very cold and your clothes are wet. The prefix hypo means below or abnormally deficient. Hypothermia is a condition in which the body’s temperature falls well below the normal 98.6 degrees Fahrenheit. If it is very hot and you have nothing to drink, you may become dehydrated and might develop hyperthermia, overheating. Another name for rabies is hydrophobia.

116
Q

The gas that is needed for burning is

A

oxygen. Combustion cannot occur in the absence of oxygen.

117
Q

The only safe blood transfusion would be

A

Group O blood into Group AB person. Antigens and antibodies are hostile to one another. If antigens of a factor are introduced into a person who has antibodies toward that factor, a severe reaction and even possible death will result. Group A blood contains A antigens and B antibodies. Group B blood contains B antigens and A antibodies. Group AB blood contains A and B antigens but no antibodies. Group AB persons can receive any group blood; they are called “universal recipients.” Group O blood contains no antigens but A and B antibodies. Group O person are called “universal donors.”

118
Q

The statement that best describes a “high” on a weather map is the

A

air pressure is greater than normal. The “highs” on a weather map are based on barometric pressure. The greater the air pressure, the higher the mercury in the barometer.

119
Q

The smallest particle of gold that still retains the characteristics of gold is

A

an atom. An atom is the smallest part of an element that retains all the properties of the element.

120
Q

Narcotics may be dangerous if used without supervision, but they are useful in medicine because they

A

relieve pain. The action of narcotics is to deaden pain.

121
Q

The primary reason why fungi are often found growing in abundance deep in the forest is that they have a

A

plentiful supply of organic matter. Fungi do not contain chlorophyll so they cannot produce their own food through photosynthesis. Since fungi must rely for their food upon decaying organic matter, the forest is a hospitable home.

122
Q

The presence of coal deposits in Alaska shows that at one time Alaska

A

had a tropical climate. Coal is formed by the partial decomposition of vegetable matter under the influence of moisture, pressure, and temperature, and in the absence of air. If there is coal in Alaska, their must once have been abundant vegetation in Alaska.

123
Q

If a person has been injured in an accident and damage to the back and neck is suspected, it is best

A

to wait for professional help. Damage to the neck and back is especially dangerous because the spinal cord is so vulnerable. Once the spinal cord is severed, paralysis is inevitable and irreversible, so if there is any question of back or neck injury, the person should be moved only by a skilled professional.

124
Q

A 1000 ton ship must displace a weight of water equal to

A

1000 tons.

125
Q

Vitamin C is also known as

A

ascorbic acid. Vitamin C, contained in citrus fruits, tomatoes, and green vegetables, is also known as ascorbic acid.

126
Q

If you are caught away from home during a thunderstorm the safest place to be is

A

in a car. Lightning is most likely to strike the highest object in an area. If you are standing in an open field or at the top of a small hill, you are likely to be the highest object and a good target. If you stand under a tree, lightning might hit the tree and cause it to fall on you. A car is grounded. If you are inside a car that is hit by lightning, the lightning will be transmitted into the ground by the car.

shadow of the moon on the earth.

130
Q

Under natural conditions, large quantities of organic matter decay after each years plant growth has been completed. As a result of such conditions,

A

soils maintain their fertility. When organic matter decays, it decomposes into its constituent elements. These elements are returned to the soil, thus increasing its fertility.

131
Q

The thin, clear layer that forms the outer coat of the eyeball is called the

A

CORNEA. Light enters the eye through the PUPIL (the opening in the center of the IRIS), travels through the transparent crystalline lens, then travels through the vitreous humor (eyeball), and finally is focused on the RETINA. The cornea, a transparent tissue, forms the outer coat of the eyeball covering the iris and pupil.

132
Q

The most likely reason why dinosaurs became extinct was

A

that they failed to adapt to a changing environment. The extinction of all sizes and varieties of dinosaurs all over the world can be explained neither by local phenomena nor on a one-by-one basis.
