Which of these digestive enzymes is not produced by the pancreas?

63% Answer Correctly

trypsin

pancreatic amylase

gastric acid

lipase


Solution

The acids produced by the pancreas contain several enzymes that aid in digestion.  Lipase converts fat to glycerol and fatty acids. Pancreatic amylase breaks down complex carbohydrates into simple sugars. Trypsin converts polypeptides (the building blocks of protein) into amino acids.

212°F is how many °C?

78% Answer Correctly

\(135 {5 \over 9}\)

0

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

The rate of vibration of sound is called:

83% Answer Correctly

amplitude

frequency

volume

period


Solution

The rate of vibration of sound is called frequency and is measured in hertz (Hz). One hertz is one repetition per second and sounds with high frequency have a higher pitch than sounds with lower frequency. Humans can hear sounds in the range of 20 Hz to 20 kHz.


4

Which of the following describes the Earth's outer core?

45% Answer Correctly

liquid

makes up most of the Earth's volume

solid

primarily solid


Solution

The Earth's core is divided into the liquid outer core (1,430 miles or 2,300 km radius) and the solid inner core (745 miles or 1,200 km radius).


5

Plant cells may generate energy through which of the following?

72% Answer Correctly

all of these

anaerobic respiration

photosynthesis

aerobic respiration


Solution

Some plant cells produce their own energy through photosynthesis which is the process by which sunlight, carbon dioxide, and water react to make sugar and oxygen. Animal cells cannot produce their own energy and, instead, generate energy when mitochondria consume outside sugar and oxygen through aerobic respiration.
