10. Define immunity, and distinguish between active and passive immunity. this should be 150 words. I will mark as BRIANILIST. thank you.

Immunity is the balanced state of multicellular organisms having adequate biological defenses to fight infection, disease, or another unwanted biological invasion, while having adequate tolerance to avoid allergy and autoimmune diseases. Each part of the immune system has a unique function. Also, the immune system is responsible for down-regulating immune responses against external harmless triggers such as food, or against the bodies' tissue. Active immunization is the induction of immunity after exposure to an antigen. Antibodies are created by the recipient and may be stored permanently. Naturally acquired active immunity occurs when the person is exposed to a live pathogen, develops the disease, and becomes immune as a result of the primary immune response. And passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally when maternal antibodies are transferred to the fetus through the placenta. Passive immunity refers to the transfer of antibodies from one individual to another.

explanation:

plate tectonics and volcanic euptions

over time, plate tectonic processes cause continents to move to different positions on the globe.

for example, britain was near to the equator 300 million years ago, and therefore was hotter than it is today. for further details look at our climate through time poster or online map.

the movement of the plates also causes volcanoes and mountains to form and these too can contribute to a change in climate.

mountain ranges formed by plate tectonics. large mountain chains can influence the circulation of air around the globe, and consequently influence the climate.   warm air might be deflected somewhere cooler by the mountains.

the correct answer is b. possesses the characteristic of compartmentalization of organelles, wherein the organelles are bound by membranes.
