Answer;
-Principal diagnosis
Explanation;
-Principal diagnosis is a condition established after study that is chiefly responsible for the admission of the patient to the hospital. The principal diagnosis is defined as the condition, after study, which occasioned the admission to the hospital.
-The principal diagnosis is not necessarily what brought the patient to the ER, but rather, what occasioned the admission. For example, a patient might present to the ER because he is dehydrated and is admitted for gastroenteritis.
Answer:
1. T cells
2. B cells
Explanation:
With increased age, people become more prone to all infections and produce fewer responses for vaccines. This is due to the lowered levels of function of immune systems against the infections.
With increased age, thymus atrophy and/or hyposecretion of hormones from thymus gland result in reduced activity of T cells against infections. Less number of T cells respond to infections.
The reduced T cell production also makes the B cells less responsive. Reduced responses of B cells towards infection results in slower immune response as antibody levels do not rise quickly.
Let’s say a desert becomes flooded. Some species would quickly go extinct, disrupting the food web. This flood might cause new species to enter the ecosystem as well, through means such as rafting. Other species would be forced to adapt to the new environment, leading to adaptation and possibly speciation. For a time the ecosystem would not be very stable, but after a relatively short time, 10 or 20 years, the ecosystem could stabilize itself. So my conclusion is that ecosystems are relatively fluid, they can adapt to almost anything if they have enough time and the change in environment isn’t too drastic.
