When compared to eukaryotic cells, prokaryotic cells are:

60% Answer Correctly

	similarly complex
	less complex
	more complex
	none of these

Solution

Cells are classified into one of two groups based on whether or not they have a nucleus. Eukaryotic cells have a nucleus, prokaryotic cells do not have a nucleus and therefore have a less complex structure than eukaryotic cells.

69% Answer Correctly

	Jupiter

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

83% Answer Correctly

	one is inherited, the other is learned
	one controls thinking, the other controls feeling
	each belongs to a different nervous system
	one controls voluntary activity, one controls involuntary activity

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.

Within DNA, a variety of a particular gene is called a(n):

55% Answer Correctly

	allele
	chromosome
	homozygous
	heterozygous

Solution

The gene is the base unit of inheritance and is contained within DNA. A gene may come in several varieties (alleles) and there are a pair of alleles for every gene. If the alleles are alike, a person is homozygous for that gene. If the alleles are different, heterozygous.
