Answer:
Humoral immunity:
Humoral immunity is mediated by the macromolecules present in the extracellular fluid. This immunity provides protection against the pathogens present in the extracellular fluid. B- cells are mainly produced by the humoral immunity. The plasma cell and memory cells are generated in the human body. Antibodies kill the pathogens in humoral immunity.
Cell mediated immunity:
Cell mediated immunity is activated by the infected cells. This immunity provides protection against intracellular pathogens. T- cells are mainly produced by cell mediated immunity. T helper cells and T killer cells are mainly produced in the cell mediated immunity. Cytokines kill the pathogens in case of cell mediated immunity.
similarities:
1. They both show bilateral symmetry.
2. Both vertebrates and invertebrates have a functional nervous system.
3. Both vertebrates and invertebrates have a heart and a circulatory system.
4. Vertebrates and invertebrates belong to kingdom Animal.
Difference:
Invertebrates are those that do not possess a vertebral column or backbone while Vertebrates are those where vertebral column or backbone is present.
What seems to fit in the blank would be "offspring,'' but that wouldn't be true.
