Answer:

Option). the ability to remember the antigen it encounters

Explanation:

The adaptive or acquired immunity is a type of immunity, which develops by the exposure of pathogens during lifetime. Four features of adaptive immunity includes specificity, diversity, memory, and ability to differentiate between self and non-self.

Cells of adaptive immunity (B cells and T cells) are specific for pathogens. Once the antigens or their components are recognized by pathogens, these cells produce effector cells and memory cells.

These are the memory cells that remember the antigens and provide a rapid and more efficient response during subsequent encounters of those antigens.

Thus, the correct answer is first option.

What happens to biological productivity in areas where two major currents meet?
Drupady [299]
Areas where cold and warm currents meet have a tendency to have regular foggy situations, as the overlying warm and cold air come in contact with each other. They also have a tendency to have high biological productivity, because plankton growth is embolden by the mixing of warm and cold currents. Some of the world's most productive fishing grounds are situated where warm and cold currents meet. For example, where Labrador Current (cold) and Gulf Stream (warm) meet, a dense fog is there and it is one of the richest fishing grounds of the world.
