ans 23---Dehydration process by removal of 2 hydrogen molecules and one oxygen molecule. hence removal of h2o molecule. Hence the answer is option A
ans24--- An atom of same element can exist in diffrent types. these are known as isotopes. these have same number of protons and electrons but differ in number of neutons which amke the heavier or lighter. hence the correct option is C.
Ans 25--- viruses are not made up of celss infact they are just amde up of a core genetic material either rna or a dna which is protected by a proteinaceous protective outer coat and by an envelop. therefore the wrong statement and the answer is option B
Ans26--- Number of protons and electrons determine the identity of an element. here protons play an important role as they can not be detached from an atom where as an electron could be. Hence the correct option is D
