The asteroids in the Kuiper belt are composed of which of the following?

61% Answer Correctly

gaseous methane, ammonia, and water

frozen methane, ammonia, and water

rock

minerals
Solution

The Kuiper Belt is similar to the asteroid belt but much larger. Extending beyond the orbit of Neptune, it contains objects composed mostly of frozen methane, ammonia, and water. Most notably, the Kuiper Belt is home to Pluto, a dwarf planet that, until a 2006 reclassification, was considered the ninth planet of the solar system.

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

82% Answer Correctly

one is inherited, the other is learned

one controls thinking, the other controls feeling

one controls voluntary activity, one controls involuntary activity

each belongs to a different nervous system
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

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

55% Answer Correctly

allele

homozygous

heterozygous

chromosome
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.

4

Which of these is not a phase in cell division?

62% Answer Correctly

megaphase

cytokinesis

interphase

anaphase
Solution

Cell division is the process by which cells replicate genetic material in the nucleus and consists of several phases, beginning with interphase and ending with cytokinesis.

5

In cell biology, where does DNA replication take place?

65% Answer Correctly

Golgi apparatus

cytoplasm

nucleus

mitochondria
Solution

The cell nucleus contains the genetic material of the cell and is where DNA replication takes place.
