1

The process of diffusion allows __________ to exchange oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells.

57% Answer Correctly

veins

red blood cells

arteries

capillaries
Solution

Capillaries are small thin-walled vessels that permit the exchange of oxygen, carbon dioxide, nutrients, and waste between blood and the body's cells. This process of exchange is called diffusion.

What is a major difference between the somatic and autonomic nervous systems?

82% Answer Correctly

each belongs to a different nervous system

one controls voluntary activity, one controls involuntary activity

one is inherited, the other is learned

one controls thinking, the other controls feeling
Solution

Both are part of the peripheral nervous system. The somatic nervous system sends sensory information to the central nervous system and controls voluntary actions while the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.

3

Which of the following is not a base unit in the metric system?

87% Answer Correctly

liter

meter

degree Fahrenheit

gram
Solution

The Fahrenheit scale is used for measuring temperature in the British system. The metric system uses the Celsius scale.

4

Absolute zero is which of the following?

58% Answer Correctly

the freezing point of oxygen

the coldest temperature possible in the universe

0°C

the freezing point of hydrogen
Solution

In contrast to the Celsius scale (measured in degrees centigrade) that fixes 0° at the freezing point of water and the Fahrenheit scale that uses 32°, the Kelvin scale fixes 0 at absolute zero (-273°C) which is the lowest temperature possible in the universe.

5

Which of the following members of the food chain are most alike?

65% Answer Correctly

herbivores and autotrophs

producers and tertiary consumers

primary consumers and omnivores

scavengers and decomposers
Solution

Like decomposers, scavengers also break down the dead bodies of plants and animals into simple nutrients. The difference is that scavengers operate on much larger refuse and dead animals (carrion). Decomposers then consume the much smaller particles left over by the scavengers.
