23. Atom is made up of ........... different kinds of subatomic particles:
a. Three (electron, neutron, and proton)

there is fourth sub-particle which mass is equal to elctron and charge equal to proton ,this is called positron ; there are 4 sub-atomic particles

47. Which of the following is not a major sub division of the biosphere?
b. Stratosphere

it is lithospehere ,startospehere makes air-ecosystem where as is internal most part of the earth which do not make any eco sysetm

The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth, a closed, and self-regulating system.
