3

Which of the following is not true of light waves?

62% Answer Correctly

can travel through a vacuum

travel faster than sound waves

are mechanical waves

are electromagnetic waves
Solution

Unlike mechanical sound waves that require a physical medium for propagation, light waves are electromagnetic and can travel through empty space. Light waves are also much faster, travelling at 186,000 m/s vs. 343 m/s for sound waves.

4

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

47% Answer Correctly

nucleotides

gametes

helix

genes
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.

5

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

65% Answer Correctly

scavengers and decomposers

primary consumers and omnivores

herbivores and autotrophs

producers and tertiary consumers
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.
