Question

differenc BETWEEN THE FOLLOWING:
1. Distinguish between vaccines and antibodies.
Metals and non-metals based on both chemical and physical properties.
3. Conductors and insulators​

Answer 1

Answer:

Explanation:

It is true that natural infection almost always causes better immunity than vaccines. Whereas immunity from disease often follows a single natural infection, immunity from vaccines usually occurs only after several doses. However, the difference between vaccination and natural infection is the price paid for immunity.

Answer 2

Answer:

1.

 Vaccine:A serum that contain antigen or weak microorganism that stimulate antibody production in body and develop immunity against specific disease.

  Antibody:These are specific proteins which are synthesized by the vertebrate in response to a antigen and destroy the antigen that stimulate their production.they are synthesized by B-lymphocytes.

2.

  Metals: These are the elements that form positive ions by losing electrons.They have low value of ionization energy, electron affinity and electronegativity.

 Non-metals:These are the elements hat form negative ions by gaining electrons.They have high values of ionization energy, electron affinity and electronegativity.

3.

Conductors:These are the elements that allow electricity to pass.usually metals are conductors.

 Insulators:These are the elements that do not allow electricity to pass.Usually non-metals are insulators with few exceptions.
