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:
With microscope.
Explanation:
Every cell has a selective permeable membrane in which smaller molecules can pass whereas bigger molecules stays outside the cell which can be seen in the cell with the use of microscope because it only occurs inside the cell. The movement of ions or molecules in the cell through a semi permeable membrane is called Osmosis. The movement of ions or molecules sometime needs energy we called it active transport and sometimes it moves without the use of energy is known as passive transport.
Endergonic reaction- reactions where chemical bonds are formed
exergonic reaction- reactions where the change in free energy is negative
