The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
kinetic |
|
gravitational |
|
inherent |
|
potential |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
Within DNA, a variety of a particular gene is called a(n):
allele |
|
chromosome |
|
heterozygous |
|
homozygous |
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.
When compared to eukaryotic cells, prokaryotic cells are:
less complex |
|
none of these |
|
similarly complex |
|
more complex |
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.
Traits represented by genes may be which of the following?
all of these |
|
dominant |
|
recessive |
|
expressed |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
A dominant trait will be expressed when paired with:
a chromosome |
|
a dominant trait |
|
a gene |
|
a recessive trait |
The traits represented by genes are inherited independently of each other (one from the male and one from the female gamete) and a trait can be dominant or recessive. A dominant trait will be expressed when paired with a recessive trait while two copies of a recessive trait (one from each parent) must be present for the recessive trait to be expressed.
