There are choices for this question namely:
<span>a. 40% to 50%
b. 50% to 70%
c. 70% to 85%
d. 85% to 100%
The correct answer is 50% to 70%. Moderate-intensity activity is noted when a person reaches 50% to 70% of his or her maximum heart rate in exercise. The maximum heart rate is determined by subtracting the age to 220.
<em>For example, a 54-year-old male with type 2 diabetes needs to have moderate intensity activity. His maximum heart rate is (220-54) which is 166 bpm. 50% to 70% of 166 is 83-116 bpm. Therefore he should exercise and raise his heart rate at 83-116 bpm. </em>

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.
