Explanation:
Cell-mediated immunity is primarily driven by mature T cells, macrophages, and the release of cytokines in response to an antigen. T cells involved in cell-mediated immunity rely on antigen-presenting cells that contain membrane-bound MHC class I proteins in order to recognize intracellular target antigens.
Answer:
Stage III Interpretation
Explanation:
There are three stages of perception process
• Exposure
• Attention
• Interpretation
During perception, the sensory receptors are active and they receive stimulus from their surroundings. However, the complete perception of any stimulus is interpreted by the brain because only brain is capable of differentiating between the sensory stimulus based on the pathway followed by them. On the basis of perceived information, action potential signals are generated that are sent back to the sensory organ (perceiving the stimulus at their end) for further responses.
Answer:
D) receptor tyrosine kinases
Explanation:
Protein kinase receptors are simply saying receptors with associated kinases (usually tyrosine kinases).
Protein kinases are enzymes that have the ability to modulate other enzymes (or some other proteins) by adding the phosphate group. This is known as phosphorilation process. As a result of structural change, protein can change its activity (phosphorilation usually increase the activity).
Such receptors are involved in a many processes within an organism that are important for the cellular growth, differentiation, metabolism
The first answer because the larger could reproduce and small could hide better.
