Scavengers break down the dead bodies of plants and animals into which of the following?

65% Answer Correctly

producers

simple nutrients

complex carbohydrates

carrion
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.

3

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 controls thinking, the other controls feeling

one is inherited, the other is learned
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.

4

A person's genotype is their genetic makeup and includes:

81% Answer Correctly

dominant alleles

recessive alleles

phenotypes

5

As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.

65% Answer Correctly

pushes above

pushes under

mixes with

cancels out
Solution

A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.
