Immunity that results from antibodies that pass the placenta from mother to fetus is called immunity. select one: a. auto b. active c. natural passive d. innate

The correct answer is C. Natural passive immunity

Explanation:

The word "immunity" refers to the defenses organism have to respond to diseases, infection or harmful microorganism, which guarantees the organism survives. This immunity can be classified into innate when it is linked to the gene of the organism, as adaptative when it is developed due to the contact of a harmful agent or as natural passive when it is transferred from an individual to other which often occurs as antibodies are transferred through from the mother to the fetus. Considering this, the type of immunity that results from antibodies that pass the placenta from mother to fetus is the natural passive immunity.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
