Answers :
1). Answer: a)
If on slight displacement from equilibrium position, a body has tendency to regain its original position, it is said to be inStable equilibrium.
2). Answer: c)
SI Unit of work is Joule.
3). Answer: c)
Centrifugal force is equal and opposite of centripetal force
4). Answer: c)
Organic compounds are molecules associated with living organisms. These include carbohydrates, lipids, nucleic acids, proteins, enzymes, and hydrocarbon fuels.
5). Answer: b)
The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particles with half-integer spin) cannot occupy the same quantum state within a quantum system simultaneously. In the case of electrons in atoms, it can be stated as follows: it is impossible for two electrons of a poly-electron atom to have the same values of the four quantum numbers: n, the principal quantum number, ℓ, the angular momentum quantum number, mℓ, the magnetic quantum number, and ms, the spin quantum number. For example, if two electrons reside in the same orbital, and if their n, ℓ, and mℓ values are the same, then their ms must be different, and thus the electrons must have opposite half-integer spin projections of 1/2 and −1/2. This principle was formulated by Austrian physicist Wolfgang Pauli in 1925 for electrons, and later extended to all fermions with his spin–statistics theorem of 1940.
6). Answer: c)
Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Bacterial cell walls are different from the cell walls of plants and fungi which are made of cellulose and chitin, respectively.
7). Answer: c)
Genera Plantarum is a publication of Swedish naturalist Carlous Linnaeus
8). Answer: c)
Wheat leaf rust is a fungal disease that affects wheat, barley and rye stems, leaves and grains. In temperate zones it is destructive on winter wheat because the pathogen overwinters
9). Answer: b)
Simon Commission was formed in the year 1927.
10). Answer: d)
Term Carat is used to describe the mass of gem. A 1 carat diamond for example has a mass of 0.20 g. The Karat is the common unit to describe the purity of gold. 24 karat is 100 % pure. A gold ring which is 50% pure is 12 Karat.
