The correct answer is D. < 2.0

Explanation:

Earthquakes occur as energy is released from tectonic plates; these are commonly measured using a scale from 1 to 8 or 9. In this scale, earthquakes with a magnitude of 2 or less (< 2.0) are considered microearthquakes only registered by seismograph (an instrument that registers ground movements) but which are not commonly felt by people.

On the other hand earthquakes between 3.0 and 4.0 (minor earthquakes) can be felt by some people and earthquakes from higher magnitudes including moderate, strong, major and great earthquakes (from 4 to 8or 9) are felt by most people and also lead to damages on infrastructures that increases with magnitude. Thus, if a seismograph records an earthquake but scientists do not feel it has a magnitude < 2.0.

A child was exposed to a disease-causing virus (most likely chicken pox from the Varicella zoster virus) when he was 5 years old
STatiana [176]

Answer: What is expected to happen is that the secondary immune system acts immediately against the virus.

Explanation:

When a virus first enters our body, in order to defend itself, the body must first recognize what the antigen is in order to fight it through <u>antibodies</u>. Once it does it will keep a memory of it that it can use if this virus enters the body again. <u>This will be done through the secondary immune system</u>.

As the body already recognizes the antigen, it knows how to fight it immediately, generating a thousand times the amount of antibodies generated the first time.

Thanks to its memory cells, the virus will remain much less time in the body.
