1

Blood is delivered to bodily tissues through:

48% Answer Correctly

plasma

arterioles

veins

capillaries
Solution

The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.

2

The pitch of the siren of an approaching ambulance changes as it approaches you. This is an example of which of the following?

70% Answer Correctly

Doppler effect

reflection

sound radiation

refraction
Solution

The Doppler effect occurs when the source or listener (or both) of sound waves is moving. If they're moving closer together, the listener perceives the sound with a higher pitch and, when they're moving apart, the listener perceives the sound with a lower pitch.

3

Which is the proper order of Earth's atmospheric layers from the surface up to space?

57% Answer Correctly

mesosphere, thermosphere, stratosphere, troposphere

troposphere, stratosphere, mesosphere, thermosphere

stratosphere, troposphere, mesosphere, thermosphere

thermosphere, mesosphere, stratosphere, troposphere
Solution

The troposphere is the closest layer to Earth, followed by the stratosphere, mesosphere, and finally the thermosphere which borders space.

4

Blood is circulated throughout the body via:

37% Answer Correctly

capillaries

veins

arterioles

aorta
Solution

The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.

5

Cellular fermentation takes place:

50% Answer Correctly

in plant cells

in the presence of oxygen

aerobically

anaerobically
Solution

If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
