Mitosis plays an important part in the life cycle of most living things, its a type of asexual reproduction it makes similar copies of a single cell
Photosynthesis and cellular respiration basically are dependent on one another. Photosynthesis produces a product of glucose, and oxygen as a byproduct. Cellular respiration uses both glucose and oxygen to produce carbon dioxide and water which are needed for photosynthesis to occur. Humans, animals and plants depend on the cycle of cellular respiration and photosynthesis for survival.
One hypothesis that is in the scientific community which relates to the origin of the building blocks for life is that they were formed when lightning struck water.
Answer:
Immediately, the pathogen has been recognized:
Macrophages acts as the first line of defence by engulfing pathogens identified by antigens which will now present the antibody shape to a helper T cell.
The Helper T cells produce a signal to plasma and Memory B cells to yield antibodies that attach to the antigens. The cytotoxic cells that leads to cell death are activated by the helper T cells.
Antibodies helps to immobilize pathogen for macrophage to feed on.
if the pathogen comes back a 2nd time the memory cells helps in quick and efficient recovery by producing the specific B and T cells for the antigen.
