Active Immunity, Immunity which is acquired by the own immune response of the body.
Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.

Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.
a vaccine works by training the immune system to recognize and fight pathogens, either viruses or bacteria. so certain molecules from the pathogen must be introduced into the body to trigger an immune response. so basically your not really immune your body will just know how to deal with it
B. It prompts the kidneys to reabsorb more water into the bloodstream to dilute the salts.
C.
It inhibits the skin to sweat. This retains more water into the bloodstream to dilute the salts.
Antidiuretic hormone (ADH), also known as arginine vasopressin (AVP), is a hormone that regulates water balance in the body by managing how much water the kidneys reabsorb while filtering wastes from the blood. Option B is correct.
To dilute the salts, it causes the kidneys to reabsorb more water into the bloodstream.
The hormone ADH, also known as vasopressin, is generated in the hypothalamus and kept in the posterior pituitary gland. ADH is generated in reaction to excessive salt levels in the blood or low water levels in the blood. ADH then goes to the kidneys, where it interacts to receptors on collecting duct cells.

The right answer is C) Make sure electrical hazards are resolved immediately.
The different electrical risks are:
Risk of direct contact with an electrified part
Risk of indirect contact with a conductive part accidentally switched on
Risk of "remote" electrification (without contact), by priming
Risks of fire and exposure, due in particular to arcing during a short circuit, and the accumulation of static electricity causing sparks.
To stay safe around electricity, Ted needs to avoid touching any wires that are currently attached to the outlet. This is to avoid any contact and sudden shock since the human body is composed of water which is a viable conductor of energy.
Tap root
the fish release gas so that can go up above the water breath and then go back into the water
Salt marshes are primarily influenced by the tides
