3). Answer: D
It is a form of antimatter because, when a positron encounters an electron, the two completely annihilate to yield energy. The existence of the positron was predicted in 1928 by physicist Paul Dirac, and positrons were discovered experimentally in 1932 by physicist Carl Anderson.
4). Answer: B
Isoelectronicity is the phenomenon of two or more chemical species (atoms, molecules, radicals, ions etc.) differing in the atoms that comprise them but having the same number of valence electrons and the same structure (that is, the same number of atoms with the same connectivity). The species concerned are termed isoelectronic.
5). Answer: B
Rutherford atomic model, also called nuclear atom or planetary model of the atom, description of the structure of atoms proposed (1911) by the New Zealand-born physicist Ernest Rutherford.
6). Answer: A
Boric Acid is an acidic hydrate of boric oxide with mild antiseptic, antifungal, and antiviral properties.
7). Answer: B
Arthrology is the science concerned with the study of anatomy, function, dysfunction and treatment of joints and articulations
8). Answer: D
The nucleus maintains the integrity of genes and controls the activities of the cell by regulating gene expression—the nucleus is, therefore, the control center of the cell.
9). Answer: C
