Answer:
All organisms that have life, both plants and animals.
Explanation:
You didn't provide an illustration, but I guess I can still help. Biotic factor means that it has life, abiotic means it's not alive (hence the a- at the beginning.) Some biotic factors of a pond ecosystem include: earthworms, fishes, frogs, plants and insects.
I'm pretty sure it's primary growth. I might not have studied this type of biology yet, but secondary growth would definitely not be the answer.<span />
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.
