Answer: Sickle cell anemia is a molecular and genetic disease.
Sickle cell anemia is not infectious
Diseases caused by microorganisms are infectious.
Explanation: Sickle cell disease is a molecular disease,it involves molecular change in the structure of the molecular base present in the molecule DNA which caused the amino acids and the beta side of the hemoglobin to change accordingly.
It is genetic as it can be transferred from one generation to the next, children can inherit it from their parents.
A person can not be infected with Sickle cell anemia,it is not infectious unlike diseases caused by microorganisms that can infect others who come in contact with the disease either through blood or other routes.

Answer:
Rudolf Virchow
Explanation:
During his studies on inflammatory exudates, Rudolf Virchow observed that the increased number of cells in the exudates was due to the formation of new cells by pre-existing cells. He also studied that the formation of new cells from the preexisting cells is responsible for wound healing and for normal growth and development of living beings.

Cells have different shapes because they do different things. ... The shapes of cells have evolved to help them carry out their specific function in the body, so looking at a cell's shape can give clues about what it does. Neurons are cells in the brain and nervous system.
Answer:
Explanation:
A. The bacteria DNA will contain most of the radioactivity. The reason is that the DNA is made up of a sugar phosphate backbone which forms its structural framework. One grinding up the bacteria, the radioactive phosphate will likely react with the DNA.
B. In the second instance, the proteins will contain the radioactivity this is because, the DNA does not have any reaction with sulphur, on the other hand, proteins contain about 3 - 6% sulphur.
