What provides active defense against pathogens? And why?

Answers

Answer:

Antibodies play a role in eliminating infectious pathogens, preventing the hematologic spread, and providing future protection if re-exposed. Active immunity utilizes cytotoxic T lymphocytes, TH1, TH2 cells, and activated B cells to target infections from multiple angles.

Explanation:

ANSWER:
The innate immune responses are the first line of defense against invading pathogens. They are also required to initiate specific adaptive immune responses. Innate immune responses rely on the body's ability to recognize conserved features of pathogens that are not present in the uninfected host.

Mr. Allen wanted to fill balloons for a party. He rented a helium tank that contained 0.4 cubic meters of helium gas. He was concerned that the gas would not fill many balloons, but it filled 27 large balloons! Why was the small tank of helium gas able to fill so many balloons?

A. Helium mixed with air when it came out of the tank.

B. The helium expanded to fill its new containers, the balloons.

C. Helium molecules are very small in size.

D. The volume of gas in the balloons equaled the volume of gas in the tank.

Answers

The helium expanded to fill its new containers, the balloons, option c is correct.

As we know the behavior of gases, we can understand that they expand. In this case, the small tank of helium gas was sufficient to fill many balloons, helium expanded to fill all the balloons.

Helium is a noble gas. Like all other elements in a gaseous state, helium atoms are also spaced apart. This property of gas helps manufacturers to compress large amounts of gas into small containers.

This is the same scenario that is given in the question, the small tank of helium contains a large amount of gas compressed in it. Therefore, when the gas is released from a small container, it expands to fill its new containers i.e. balloons in this case, because of this the small tank was able to fill many balloons.
