Rina8888 [55]

Answer:

Adaptive defenses include both humoral and cellular immunity.

Explanation:

The innate immune response is the non-specific immune response and serves to provide an immediate and general immune response. The adaptive immune responses are the specific immune responses. Adaptive immune responses include cell-mediated immunity and antibody-mediated immunity.

Cell-mediated immunity includes T cells (cytotoxic and helper T cells) while antibody-mediated immunity includes the production of antibodies from B cells. Binding of antigen to B cells is followed by their transformation into plasma cells and produce antibodies. Some of the activated B cells form memory B cells that are responsible for quicker and strong secondary immune responses.

ipn [44]

Answer: False

A lake is a water body that is surrounded by land. The water in the lake comes from melting glaciers, rain, groundwater, rivers. Lake formation also occurs when a water body is restricted to it's natural flow. Erosion due to wind  and water will limit the life of lake. As, soil removed during landslides or mudslides from hills or mountains get settled as debris at the bottom of lake will cause water pollution. Also, soil coming from agricultural field through water will carry in it fertilizers ,which will promote excessive plant and algal growth in lakes therefore, oxygen content of lake water will decrease which lead to death of animals residing in lake hence, will ultimately lead to water pollution ,which will be responsible for limiting the life of lake.
