Explanation:
Static electricity is a form of electrical energy which is produced by the imbalance of positive and negative charge.
The characteristics of static electricity are:
1. The charges do not move and therefore called static in nature.
2. The charges of static electricity possess less energy, therefore, remain for a small period.
3. Static electricity is build up mostly on non- humid dry days.
4. The charge of static electricity does not generate electric fields but they are constant.
5. Due to a constant electric field, no magnetic field is generated.
6. The static electricity can be observed in the lightning, Van-de graff generator and xerox machines.
Extraction, homogenization, and centrifugation are the three processes in cell fractionation.
Cell fractionation is a method for dividing cellular components while yet maintaining each component's unique functionality. This technique was initially applied to show where distinct biochemical activities are located within cells. Subcellular fractionation is also used to help with illness detection and to offer an enhanced source of protein for further purification. To prevent osmotic damage, tissue is routinely homogenized in an isotonic buffer solution. Grinding, mincing, chopping, pressure changes, osmotic shock, freeze-thawing, and ultrasonic waves are a few of the mechanisms for homogenization. After that, the samples are maintained cool to avoid enzymatic deterioration. It is the development of a uniform mass of cells (cell homogenate or cell suspension).

Answer: The correct answer is the last option.
Explanation:
Carrier identification test is a screening test that tells if a person is carrier of a particular autosomal recessive disease. It helps in determining the possibility of passing that disease to a child.
Genetic counsellor is professional who is expert in human genetics, research, lab work, counselling, et cetera. After the test, it is best to contact a genetic counsellor as he can explain the family pedigree of the disease. He can best explain the probability of passing a genetic disease to the child.
