Rajiv has a textile firm. For carrying out production, Rajiv spent money on procuring thread from traders, buying machines and equipment and built a warehouse to store the cloth produced. The expenditure incurred by Rajiv for conducting the production process is termed as:
Assertion (A): Kerala has low infant mortality.Reason(R): It has the adequate provision of basic health and education facilities.
Mohan is an agricultural labourer. There are several months in a year when he has no work and needs credit to meet his daily expenses. He depends upon his employer, the landowner for credit which charges an interest rate of 5 per cent per month. Mohan repays the money by working physically for the landowner on his farmland.Over the years his debt will
In living cells, such as E. coli, the process of replication requires a set of catalysts (enzymes). The main enzyme is referred to as DNA-dependent DNA polymerase, since it uses a DNA template to catalyse the polymerisation of deoxynucleotides. These enzymes are highly efficient enzymes as they have to catalyse polymerisation of a large number of nucleotides in a very short time. E. coli that has only 4.6 ×106 bp), completes the process of replication within 18 minutes; that means the average rate of polymerisation has to be approximately 2000 bp per second. Deoxyribonucleoside triphosphates serve dual purposes. In addition to acting as substrates, they provide energy for polymerisation reaction (the two terminal phosphates in a deoxynucleoside triphosphates are high-energy phosphates, same as in case of ATP). In addition to DNA-dependent DNA polymerases, many additional enzymes are required to complete the process of replication with high degree of accuracy.
A first order reaction has the rate constant, k=4.6×10−3s−1 . The number of correct statement/s from thefollowing is/are __________Given : log 3 = 0.48A. Reaction completes in 1000 s.B. The reaction has a half-life of 500 s.C. The time required for 10% completion is 25 times the time required for 90% completion.D. The degree of dissociation is equal to (1-e-kt)E. The rate and the rate constant have the same unit
A metal complex having composition Cr(NH3)4Cl2Br has been isolated in two forms (X) and (Y). The form (X) reacts with AgNO3 to give a white precipitate readily soluble in dilute aqueous Ammonia, whereas (Y) gives a pale-yellow precipitate soluble in concentrate ammonia.
A point charge q is placed within the cavity of an electrically neutral conducting shell whose outer surface has spherical shape figure. Then:
