mark because it is half the distance of 1 meter. 100 centimeters equal 1 meter.
(50 cm)
The chief nutrient in lean meat is - CORRECT ANSWER Meat provides much essential
protein in the form the body needs. Protein is the principal nutrient in lean meat.
(Protein)
On the Celsius temperature scale, each Celsius degree represents what fraction of the
temperature range between the freezing and boiling points of water? - CORRECT
ANSWER The freezing point of water is 0ºC; the boiling point of water is 100ºC. There
is a 100º temperature range between the freezing and boiling points of water.
1°C=1100 of this range. (1100)
The principal metal used to manufacture steel is - CORRECT ANSWER Iron is the
major component in the production of steel(iron)
Shooting stars" are - CORRECT ANSWER Meteors or "shooting stars" come into the
earth's atmosphere from outer space with high velocity. The resistance offered by the
earth's atmosphere makes these meteors incandescent in flight.
(meteors)
Two children are seated on a seesaw. The first child, seated 4 feet from the center,
weighs 80 pounds. If the second child weighs 40 pounds, how far from the center must
that child sit to balance the seesaw? - CORRECT ANSWER To balance the seesaw,
the product of the weight and the distance from the weight to the fulcrum must be the
same for both sides. Let x = distance from center of seesaw for the second child.
x×40=4×8040x=320x=32040=8feet
(8 feet)
The part of the digestive system in which most of the digested materials are absorbed
into the bloodstream is the - CORRECT ANSWER Most of the end products of digestion
are absorbed into the bloodstream while traveling through the small intestine.(Small
intestine)
, Skeletal muscles are joined to bones by tough connective tissue called - CORRECT
ANSWER Skeletal muscles are joined to bones by tendons. Tendons are so attached
that they pull on the bones and make them act like levers(tendon)
Hearing an echo is most like seeing - CORRECT ANSWER an echo is the repetition of
a sound caused by the reflection of sound waves. An image is an optical appearance of
an object produced by reflection from a mirror. (one’s image in a mirror)
Vitamin K is needed for - CORRECT ANSWER Vitamin K is a fat-soluble vitamin
needed for normal blood clotting (normal blood clotting)
If we start with 400 atoms of a radioactive substance, how many would remain after one
half-life? - CORRECT ANSWER Half-life is defined as the amount of time it takes for
half of a substance to undergo decay. A 400g sample undergoing one half-life decays
by 50%. 200 is half of 400. (200)
The primary reason designers seek to lower the center of gravity in automobiles is to -
CORRECT ANSWER The primary reason for lowering the center of gravity in
automobiles is to increase stability. Stability is increased largely by lowering the center
of gravity and by increasing the width of the automobile. (increase stability)
Substances that hasten a chemical reaction without themselves undergoing change are
called - CORRECT ANSWERA substance that changes the rate of a chemical reaction
but is itself unchanged at the end of the reaction is called a catalyst (catalysts.)
A hip joint is best described as a - CORRECT ANSWER The hip joint is a ball-and-
socket joint that permits circular movement. (ball-and-socket joint)
AIDS is a disease caused by a - CORRECT ANSWER The virus that causes AIDS is
called human immunodeficiency virus, or HIV
(Virus)
Lack of Vitamin D is often related to which of the following diseases? - CORRECT
ANSWER Rickets is a disease in which bones and teeth are weak and poorly formed. It
may be caused by insufficient Vitamin D in the diet.
(Rickets)
How old is a skeleton sample if the current amount of carbon in the bones is 3.135%?
(Assume you started with 100% and the half-life of Carbon-14 is 5,730 years.) -
CORRECT ANSWER 100% > 50 > 25 > 12.5 > 6.25 > 3.125 equals 5 half-lives. 5 ×
5,730 = 28,650 years.
(28,650 years)
A lead sinker weighs 54 grams in air, 23.8 grams in liquid A, and 28.6 grams in liquid B.
