Answer:
The correct answer is- a slow rise in the concentration of antibodies, followed by a rapid decline.
Explanation:
The first exposure of antibody in an organism generates the primary response. Initially, for some days after the exposure of antigen, there is no antibody detection in the blood and it is called the latent phase.
After the latent or lag phase, the antibodies start accumulating and reach to the peak between 7-10 days after exposure. So it takes a longer time to establish immunity in primary response.
After the immunity reaches the peak it declines rapidly that means higher immunity does not stay for a longer time. This phase is called the declining phase. Therefore, the correct answer is- a slow rise in the concentration of antibodies, followed by a rapid decline.
Answer:
b. To the extent possible, solid reagent should be added to the solid waste container and broken glass should be added to the glass waste. Hazardous materials should never be added to the glass waste, and broken glass should only be allowed in the solid waste with the TA's approval.
Explanation:
All reagents, waste, equipment, and packaging used in a laboratory should be disposed of safely and appropriately to avoid environmental contamination and to avoid an accident if improperly disposed of. In a laboratory each type of reagent, waste, packaging, and equipment must be properly disposed of and specific to each. Therefore, we can conclude that if a solid reagent beaker falls off a laboratory bench and cracks, the correct thing to do is to take the solid reagent as much as possible and add it to the solid waste container and broken glass to glass waste. Hazardous materials should never be added to glass waste, and broken glass should only be allowed on solid waste with AT approval.
