<em>B. Has the same allele on both chromosomes in a chromosome pair. </em>
<u>Here is why:</u>
Homozygous means the same, while heterozygous means different. If both of the same alleles are on both chromosomes, then it will be a homozygous.
There can be two types of homozygous alleles.
~
<em>Homozygous Dominant</em>: BB
<em>Homozygous Recessive</em>: bb
<u>Notice in both of these they were the same alleles.</u>
~
<em>Heterozygous</em>: Bb
<u>Notice how both are different alleles.</u>

Below I have attached a diagram of a Punnett square I have made.
On the left is a homozygous recessive allele pair.
On the top is a heterozygous allele pair.
B. Absolute dating uses the half-life of an element
Absolute dating is a technique that uses radioactive minerals present in rocks and fossils while relative dating compare the sample in terms of age difference. However, absolute dating is more accurate because it uses half-life of an element and provides dates in years.
Answer:
C
Explanation:
The definition of microtuble is: "a microscopic tubular structure present in numbers in the cytoplasm of cells, sometimes aggregating to form more complex structures." (google) Therefor, it would not be a part of mitosis prophase II.
Binds structures, protects/supports,
fills in spaces, transports
materials, and makes red blood cells, stores energy, immunity, repairs tissue. Resist distortion, more flexible. <span>Together, our bones, muscles, and joints — along with tendons,
ligaments, and cartilage — form our musculoskeletal system and enable us to do
everyday physical activities.</span>
