3. True
4. False

Reason + Explaination

• Snail lacks respiratory system so they can not be found underwater hence nail is a land animal not an aquatic creature..

• Amphibians lives in land and water as well they , are not found in air but aves aur the birds are found in air and they have a separate class they are not included under amphibians so this statement is also false.

• Yes human being also come under vertebrate and they have well developed brain so vertebrate animal have extremely wonderful brain and are wiser than non vertebrates. The body of vertebrates consists of the beautiful central nervous system with a great huge brain and the spinal chord.

• The first cellular form of life appeared on the planet earth contain unicellular prokaryotic organism and amoeba is one among them. It belongs to Monera phylum and here are all the unicellular animals are present. Amoeba has no well defined structure and neither a well developed division of labour so it's absolutely wrong to call it a multicellular organism that statement is false.
