Answer: Brain stem
Explanation:
The brainstem can be defined as a structure which is present in between the midbrain and the cerebrum. This controls the flow of information from the brain and the rest of the body. It also controls the functions like breathing, heart rate, consciousness, sleep and wake cycle and blood pressure. The brain stem consists of pons, midbrain and medulla oblongata.

Answer:
The answers are b) Disinfection can occur by physical or chemical mean, c) Disinfectants are used to inhibit or destroy pathogens, d)Endospores and viruses can resist disinfectant treatment and e)Disinfection can be used to treat work surfaces as well as workers (i.e., washing hands)
Explanation:
Disinfection is the process that involves the elimination of microorganisms through the use of chemical or physical agents. Among the physicists are heat, radiation, drying, etc. Chemical disinfectants are oxidizing substances that are used in solution and can be combined with detergents or some organic substances.
However, endospores and some viruses are very resistant to both physical and chemical disinfection. In endospores, this resistance is due to the fact that the protective layer of the spore is impermeable to any oxidizing agent. In viruses, the cytoplasmic membrane is composed of two layers, a hydrophobic and a hydrophilic zone, this influences the resistance to disinfectants.
The content of vaccine varies from vaccine to vaccine but it has some live form of the disease in the vaccine
Vaccine work by injecting a small amount of virus in the blood stream along some other agent which causes the body to produce antibodies which fight the infection
The school going kids receive vaccine because their body is no immunity and likely to be a carrier of diseases and spread them.
