What's the difference between active immunity and passive immunity?
Paha777 [63]

The difference between active and passive immunity is that your body produces antibodies in active immunity and in passive immunity, the antibodies are made outside the body. (D)

What is active and passive immunity?

Active immunity is a type of immunity that occurs when the immune system of a person is responsible for protecting them from a pathogen or from an infection.

Passive immunity is a type of immunity that involves the introduction of antibodies from another person or from outside the body of a person.

Antibodies are produced by an individual in active immunity but in passive immunity, antibodies are being transferred to an individual to help boost their immune system in fighting diseases.

Thus, the difference between active and passive immunity is that your body produces antibodies in active immunity and in passive immunity, the antibodies are made outside the body. (D)

anygoal [31]

ANSWER:  B, killifish

Why virus, virions, prions have no place in five kingdom classification​
Ainat [17]

Hey, there!!

There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.

As in 5 kingdoms, the only living organisms are classified.

  • Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
  • Kingdom Protista deals with the organism which have eukaryotic cells.
  • Kingdom Fungi deals with various fungal organism.
  • Kingdom Plantae deals with various type of plants.
  • Kingdom Animalia deals with various type of animals.

So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.
