<span>E. Stimulation of T-cell by APC</span>
The initial exposure of the body to an infectious agent e.g. through a vaccine, triggers an immune response most of which rapidly diminishes after the vaccination. However some cells of the immune system called lymphocytes remain with a memory of that pathogen.As a result, if the same pathogen infects a vaccinated person, the memory cells remember and recognize it and rapidly spring into action triggering a much more rapid response specific to that pathogen than the initial exposure, effectively dealing and neutralizing the pathogen.
Answer:
that's an pretty interesting question
Explanation:
For the simple reason that no digestion takes place in the human intestines. Digestion takes place in the stomach. Intestines are where the nutrients are absorbed into the body, and the conditions there are much more favourable for parasites like tapeworms. The stomach produces hydrochloric acid strong enough to burn a hole in a rug and is also home to lot of other strong digestive enzymes. Any tapeworm venturing there would get digested in seconds.
Answer:
2.2.1 O is the enzyme and N is the ligand.
2.2.2 In the figure, the enzyme shows lytic activity by generating two products like digestive enzymes.
2.2.3 Enzymes are indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction.
4 the organism would not produce new cell idk if im right
