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.
I would decide to take the test to find out if you will develop Huntington's chorea, because it is a disease that has a lethal progeny, with early treatment it is possible to live longer.
<h3>What is this Huntington's disease?</h3>
Huntington's disease is a genetic disease that affects the nervous system, causing involuntary movements, changes in behavior and motor coordination. Symptoms begin to appear in adulthood, between 35 and 45 years of age, and may worsen over time.
With this information, we can conclude that Huntington's Disease (HD) is an autosomal dominant disease, which confers a 50% risk of transmission to offspring. Although there is no cure, it is possible to prevent the transmission of this disease to future generations through PGT-M.
