I believe the answer is answer D- Nuclear decay rates are constant.
~ Good luck!
Answer:
d
Explanation:
<em>Crossing over shuffles alleles on non-sister chromatids of homologous chromosomes.</em>
At the prophase I stage of meiosis, homologous chromosomes synapsed to form a four-chromatid structure known as tetrad. Exchange of chromosomal segments between non-sister chromatids of the tetrad then takes place, a process that results in the reshuffling of genes or alleles on the non-sister chromatids.
Hence, none of the answers is correct.
Correct option: d

Answer: chromosomes line up at the spindle of equator during Metaphase phase of mitosis.
Explanation:
Mitosis is a process of cell division that take placemajorly in eukaryotic cells where a parent cell divide to give to identical daughter cells. Mitosis is divided into five stages which are prophase, prometaphase, metaphase, anaphase and telophase.
During prophase the sisters chromatics are joined together at the central point called centromere.
In prometaphase the nuclear envelope that house the nucleus breaksdown which is detached from the cytoplasm.protein formation called kinetochores is formed around the centromere.
In metaphase, centromere of the chromosomes line up at the spindle of the equator.
In anaphase the sister chromatics are separated from the centromere, they are pulled at the poles and each have identical set.
During telophase a nuclear membrane surrounds the each set of chromosomes and separate the nuclear DNA from cytoplasm.
