Chromosomes are parts of a cell that carries genetic information inform of genes, they contain DNA molecules packaged around histone proteins. Diploid number of chromosomes means that a cell has both sets of homologous chromosomes while haploid is used to refer to a cell that has one set of chromosomes and therefore a single set of genes.Mitosis is a type of cell division that takes place in the somatic cells (body cells) resulting to two daughter cells with the same number of chromosomes as the parent cell (diploid). Therefore, in this case a somatic cell will have 48 chromosomes (diploid number 2n).
Answer:
Since sickle cell disease is a disorder with an autosomal dominant inheritance pattern, and in light of the lack of data, it could be said that the only way for Pat and Tracy to have a child with sickle cell disease is for both of them to be healthy carriers of the gene, with a 25% probability.
Explanation:
Considering that both Pat and Tracy each have a sibling with a sickle cell trait and that both they and their parents are healthy, it must be assumed that some of their parents are healthy carriers:
- Pat and Tracy do not have sickle cell trait. In this case, there is no chance that they will have a child with sickle cell disease.
- Either Pat or Tracy has the trait, but the other does not. It is possible that at least one of their children is a healthy carrier.
- If both Tracy and Pat have sickle cell trait, the chances of having a child with sickle cell disease are:
Alelles R r
R RR Rr
r Rr rr
RR: healthy (25%).
Rr: healthy carrier (50%).
rr: sickle cell disease (25%).
<em>If Pat and Tracy are healthy carriers of the gene that determines sickle cell disease, the chance of having a child with the disease is 25%</em>.

Answer:
<em>UV rays are highly injurious to living organisms since </em><em>DNA</em><em> </em><em>and</em><em> </em><em>proteins</em><em> </em><em>of</em><em> </em><em>living</em><em> </em><em>organisms</em><em> </em><em>preferentially</em><em> </em><em>absorb</em><em> </em><em>U.V</em><em> </em><em>rays</em><em> </em><em>and</em><em> </em><em>it's high</em><em> </em><em>energy</em><em> </em><em>breaks</em><em> </em><em>chemical</em><em> </em><em>bonds</em><em>. UV rays damage DNA and mutation may occur. It causes ageing of the skin, damage to skin cells and various types of skin cancers.</em>
