Farad is the unit of___________?

A. inductance
B. voltage
C. capacitance
D. None of these

Farad, unit of electrical capacitance (ability to hold an electric charge), in the metre–kilogram–second system of physical units, named in honour of the English scientist Michael Faraday. The capacitance of a capacitor is one farad when one coulomb of electricity changes the potential between the plates by one volt.

Which of the following is caused by bacteria?

A. Malaria
B. Tetanus
C. Cancer
D. None of these

Tetanus, also called lockjaw, is a serious infection caused by Clostridium tetani. This bacterium produces a toxin that affects the brain and nervous system, leading to stiffness in the muscles. If Clostridium tetani spores are deposited in a wound, the neurotoxin interferes with nerves that control muscle movement

by
The over-cooking of food should be avoided because____________?A. Make the food difficult to digest
B. Reduce the nutrition value of food
C. Make food Poison
D. None

As it turns out, heat speeds up chemical reactions and this affects the food both in good and bad ways. Overcooking can affect the quality of food – firstly it makes food harder to digest and metabolize, and secondly, charred and burnt foods contain carcinogenic substances.
