LIFE SCIENCE

Detailed explanation-1: -Resistance is dependent on the ability of the host to kill pathogens. Tolerance promotes host health while having a neutral to positive impact of pathogen fitness. Immune responses are almost inevitably defined in terms of pathogen resistance.

Detailed explanation-2: -Immunity means com-plete resistance to disease; immune means not subject to attack by a path-ogenic organism or virus.

Detailed explanation-3: -Disease resistance is the ability to prevent or reduce the presence of diseases in otherwise susceptible hosts. It can arise from genetic or environmental factors, such as incomplete penetrance. Disease tolerance is different as it is the ability of a host to limit the impact of disease on host health.

Detailed explanation-4: -Types of immunity: Active natural: Body produces antibodies in response to exposure to a live pathogen. Active artificial: Body produces antibodies in response to a vaccine. Passive natural: Antibodies are passed from the mom to her baby through the placenta and breastmilk.
