So, in metals where the charge carriers (electrons) are negative, conventional current is in the opposite direction as the electrons. ... In other conductive materials, the electric current is due to the flow of both positively and negatively charged particles at the same time.
Many cases of early onset of Alzheimer’s disease are inherited
The immune response is the body's defense mechanism against the pathogens. The immune response of the body protects it from bacteria, viruses and multiple other disease causing organisms. The normal development of this protective immune response of the body is produced by as a result of the hormones which are produced by the thymus gland.
