Amylase, also called Ptyalin, which is capable of breaking down starch into simpler sugars such as maltose and dextrin that can be further broken down in the small intestine is the Enzyme present in Saliva.

Answer: B) 15 September Explanation:

Answer: C) P1V1 = P2V2 Explanation: Ideal Gas Law :: The Combined gas law or General Gas Equation is obtained by combining Boyle's Law, Charles' Law, and Gay-Lussac's Law. It shows the relationship between the pressure, volume, and temperature for a fixed mass (quantity) of gas: P1V1T1 = P2V2T2   Hence, the Boyle's law P1V1 = P2T2, relates to ideal gas equation.

Answer: C) Ethylene Explanation: Ethylene is used for Artificial Ripening of Green Fruit. Calcium carbide is also used in some countries for artificially ripening fruit. When calcium carbide comes in contact with moisture, it produces acetylene gas, which is quite similar in its effects to the natural ripening agent, ethylene

Answer: B) 41 Explanation: Given P = 54 and M = 80 According to the question, Let ‘A’ years ago, M = 3P => M - A/P - A = 3 => 80 - A = 3(54 - A) => 80 - A = 162 - 3A => 2A = 82 => A = 41 Therefore, A = 41 years ago Sweety’s mother was 3 times of Sweety’s age. Hence, at the age S = 13 and M = 39.

Answer: C) 7/8 & 3/8 Explanation: Given 0.875 and 0.375 0.875 :: After decimal point there are 3 digits 875 Now, mutiply and divide 0.875 with 1000 0.875 x 10001000 = 8751000 Now, this can be reduced to fraction 78Therefore, 0.875 as fraction = 78 Similarly, 0.375 ::  After decimal point there are 3 digits 375 Now, mutiply and divide 0.375 with 1000 0.375 x 10001000 = 3751000Now, this can be reduced to fraction 38Therefore, 0.375 as fraction = 38

Answer: C) sugars and phosphates Explanation: DNA is a double-stranded molecule twisted into a helix. The shape of DNA is a double helix, which is like a twisted ladder. The sides of the ladder are made of alternating sugar and phosphate molecules. Deoxyribose, which is a pentose, and a phosphate group are the two molecules together form the two sides of the DNA. The rungs of the ladder are pairs of 4 types of nitrogen bases.
