It is true that the primary function of the humoral, or antibody-mediated, immune response is to control freely circulating pathogens.
What is humoral immunity?
Humoral immunity is the immunity to infection due to antibodies, which circulate in the blood and lymph, and which are produced by B cells.
Generally, immunity is the resistance of an organism to disease-causing agents or foreign substances.
However, the humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells.

Answer:
A. pre-authorization
Explanation:
Is it an authorization or a precertification?
Per Healthcare.gov, a decision by your health insurer or plan that a health care service, treatment plan, prescription drug or durable medical equipment is medically necessary. Sometimes called prior authorization, prior approval or precertification. Your health insurance or plan may require preauthorization for certain services before you receive them, except in an emergency. Preauthorization isn’t a promise your health insurance or plan will cover the cost. This concept is not the easiest to understand. It would make sense that a notification and “approval” from an insurance company would then mean services will be paid. This is not the case and is precisely where the predetermination of benefits come into play, in addition to understanding reimbursement policies set up by payers themselves.
Answer:
a. in the bottom of the atrium just above the ventricles
Explanation:
AV node -
It helps to control the heart rate , it serves as an electrical relay station , reduces the electrical current which is sent by the SA node .
The location of the AV node , is at the lower back section of the inter atrial septum , and conducts the electrical impulse normally from the atria to ventricles .
To have full confidence in the research results, conduct three studies done the same way, each with 1,000 people.
<h3>What is a research?</h3>
- Research is careful investigation of a problem and study of relevant materials in order to establish new concepts and reach conclusion.
- Research can be of 3 types: descriptive, exploratory and casual.
- A research process consists of following steps: Identification of problem, formulating hypothesis, literature review, research design, experimentation, results and conclusion.
- The main aim of research is to improve lifestyle, prevent diseases by enhancing knowledge through different concepts and ideas.
- When a new drug is introduced in the market, several research trials are conducted to see the effectiveness of the drug in curing a disease and to check for any side effects.
