- b)To illustrate evolutionary relationships
- c)To measure animal size
- d)To label organisms
Correct answer is option 'B'. Can you explain this answer?
a)
To water plants
b)
To illustrate evolutionary relationships
c)
To measure animal size
d)
To label organisms

Which classification level is broader than family but narrower than phylum?- a)Genus
- b)Order
- c)Class
- d)Kingdom
Correct answer is option 'C'. Can you explain this answer?
a)
Genus
b)
Order
c)
Class
d)
Kingdom

Which of the following is NOT a kingdom in biological classification?- a)Animalia
- b)Fungus
- c)Protista
- d)Elements
Correct answer is option 'D'. Can you explain this answer?
a)
Animalia
b)
Fungus
c)
Protista
d)
Elements
