____ immunity results when antibodies produced in another animal are introduced into your body.

Answers

Answer:

Passive

Explanation:

In addition to innate immunity and acquired immunity, there is a different type of immunity called passive immunity.

This arises when someone receives the antibodies from someone else for the purpose of preventing (or facing) an infectious disease.

While these antibodies last a few weeks or months, they have the benefit of providing immediate protection.

Examples of passive immunity:

- They are the maternal antibodies that babies receive through the placenta during pregnancy.

- Injection of antisera, produced in animals or other people, such as serum immuniglobulin for hepatitis and tetanus antitoxin.
this is called artificially acquired passive immunity

What are the three stages of volcanic activity

Answers

The three stages of volcanic activity are active, dormant, and extinct.

An active volcano is one which has recently erupted and there is a possibility that it may erupt soon. A dormant volcano is one which has not erupted in a long time but there is a possibility it can erupt in the future. Last, but not least an extinct volcano is one in which it has no magma activity and shows no signs of ever erupting again.

Hope this helped :)
