Essa energia térmica pode ser convertida em energia mecânica, elétrica e outras formas de energia. A energia térmica também é liberada quando o alimento ingerido pelos herbívoros, apenas 10% da energia é transferida de um nível trófico para outro, enquanto 90% da energia é liberada para a atmosfera.

Katyanochek1 [597]

Answer:

Humoral response.

  • Plasma cells
  • Antibodies
  • B-cells

Cell mediated response.

  • Antigen presenting cells.
  • Helper T-cells and cytokines.
  • Cytotoxic T- cells

Both.

  • Memory cell

Explanation:

  • Immunity is typically divided into two categories- innate and adaptive.
  • Innate immunity is present since birth and consist of many factors that are relatively non-specific.
  • Adaptive immunity is also known as specific or acquired immunity, is capable of recognizing and selectively eliminating specific foreign antigen.
  • Adaptive immunity displays four characteristic features; Antigen specificity, Immunologic memory, Diversity, Self or non-self recognition.

  • There are two branches of acquired immunity, which involve different sets of participants and different purposes but one common aim: to eliminate the antigen.
  • One arm of adaptive immune response is mediated by B-Cells and circulating antibodies. This is referred to as humoral immunity.

  • The other arm of adaptive immune response is mediated by T-cells, which do not synthesize antibodies but release cytokines that affect other cells.
  • T-cell receptors do not form antibodies  but perform various effector functions when antigen presenting cells bring antigen into the secondary lymphoid organ.
  • T-cells are of two types ; T- helper cell and T-cytotoxic cells.
