Answer: C) 12 Explanation: we can do this by trial and error method. Putting x = 2,we get 2²(2² - 1) = 12.checking with other integers, the above equation always gives a value which is a multiple of 12,So, x²(x² - 1) is always divisible by 12.

Nucleotides are the building blocks of the DNA and RNA used as genetic material. Nucleotides also are used for cell signaling and to transport energy throughout cells. Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts:: 1. Nitrogenous Base2. Pentose Sugar3. Phosphate Group.

Answer: D) all of the above Explanation:

Answer: B) 36 c Explanation: Monday + Tuesday + Wednesday = 37 x 3 -----------(1)Tuesday + Wednesday + Thursday = 34 x 3---------(2)Thursday = 4/5 of Monday ------------------(3)subtract eqn (1) from (2) we get,Thursday - Monday = -9 => Monday - Thursday = 9.......(4)From (3) & (4), we get So,Thursday = 36 C

Answer: C) 12 Explanation: -4-(-10) = -4+10 = 6   -10-(-4) = -10+4= -6   Therefore, 6-(-6) = 6+6 = 12

Answer: B) 24 Explanation: Let the numbers be 3x, 3x + 3 and 3x + 6.Then,3x + (3x + 3) + (3x + 6) = 729x = 63x = 7Largest number = 3x + 6 = 27. => Second largest number = 27 - 3 = 24

Answer: D) All the above Explanation: Glycolysis is the chemical process that converts glucose C₆H₁₂O₆, into Pyruvate, CH₃COCOO− + H⁺.   It represents the first stage in the chemical oxidation of glucose by a cell. The free energy released in this process is used to form the high-energy molecules ATP and NADH.
