1

The __________ is a system of muscles that allows breathing.

74% Answer Correctly

trachea

pulmonary

bronchioles

diaphragm


Solution

The diaphragm is a system of muscles that allows breathing. During inhalation, the diaphragm expands and air rushes in to fill the space created. Then, during exhalation, the diaphragm contracts and forces the air back out.


2

212°F is how many °C?

77% Answer Correctly

0

\(135 {5 \over 9}\)

100

-100


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (212 - 32)\)

\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)

\(C° = {900 \over 9}\)

\(C° = 100\)


3

During digestion, the kidneys filter substances from the blood. Which of the following is not filtered by the kidneys?

73% Answer Correctly

water

salt

minerals

fats


Solution

Chemical waste like excess water, minerals, and salt are filtered from the blood by the kidneys and secreted into the urine. Urine is transported from the kidneys to the bladder through ureters.


4

Sound travels fastest through which of the following media?

48% Answer Correctly

water

vacuum

air

metal


Solution

The speed of a sound wave will vary with the medium.  Sound travels fastest through media that has particles that are very close together, like metal. Thus, it travels faster through water than through air and doesn't travel at all through a vacuum (there are no particles in empty space to vibrate).


5

DNA is encoded through a combination of which of the following?

47% Answer Correctly

helix

genes

nucleotides

gametes


Solution

Deoxyribonucleic acid (DNA) is the molecule that contains genetic information. DNA is encoded through a combination of nucleotides that bind together in a specific double helix pattern.
