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.
Cardiovascular fitness is best described as B. the ability of the body
to transport oxygenated blood efficiently. Cardiovascular fitness is
improved by regular aerobic exercises and help to strengthen the cardiac
muscles, making the heart more efficient in pumping blood through the
body. Moreover, cardiac efficiency decreases the resting heart rate of a
person as their heart is more effective in transporting blood with each
contraction.
