Shivering
Explanation: shivering action is an act to warm a homoeothermic body. Sweating makes the body cool, panting don’t keep body warm and dilating blood vessels does not keep body warm instead constriction of blood vessels is the initial process to conserve body heat followed by waves of muscle contraction, which is nothing but shivering. Alteration of the set point in torpor is also not the right answer
-identify the symptoms that people develop due to the strain
-work on an effective vaccine to help prevent the spread of the virus
Answer;
The above statement is true
Explanation;
-Complement is a system of plasma proteins that can be activated directly by pathogens or indirectly by pathogen-bound antibody, leading to a cascade of reactions that occurs on the surface of pathogens and generates active components with various effector functions.
-C3b is the larger of two elements formed by the cleavage of complement component 3, and is considered an important part of the innate immune system. C3b is potent in opsonization: tagging pathogens, immune complexes (antigen-antibody), and apoptotic cells for phagocytosis.
The answer would be C, d<span>isease may lead to a decline in the reproductive rate of the species’ main predator.
