Answer: C) Fructose Explanation: Fructose is an Organic molecule among the given options.    Organic Molecules : An organic molecule is one which contains carbon, although not all compounds that contain carbon are organic molecules. Noticeable exceptions are carbon monoxide (CO), carbon dioxide (CO2), carbonates (e.g. calcium carbonate), carbides (e.g. calcium carbide) and cyanides (e.g. sodium cyanide). Pure carbon compounds such as diamond and graphite are also not organic compounds. Organic molecules can range in size from simple molecules to complex structures containing thousands of atoms.   Although carbon is present in all organic compounds, other elements such as hydrogen (H), oxygen(O), nitrogen (N), sulfur (S) and phosphorus (P) are also common in these molecules.   In simple, Molecules needed for life that have carbon are called Organic Molecules.

Answer: D) 3.785 kgs Explanation: 1 Gallon = 3.785 kgs Gallon is a unit of measurement of liquid. We know that 1 gallon = 3.785 liters But we know that, 1 cubic meter = 1000 lit or 1000 kgs => 1 lit = 1 kg Hence,  1 gallon = 3.785 lit = 3.785 kgs.

Answer: C) 7:5 Explanation: Milk in 1-litre mixture of A = 4/7 litre.  Milk in 1-litre mixture of B = 2/5 litre.  Milk in 1-litre mixture of C = 1/2 litre.   By rule of alligation we have required ratio X:Y       X                  :                 Y     4/7                                2/5              \                      /               (Mean ratio)                   (1/2)             /                      \  (1/2 – 2/5)     :       (4/7 – 1/2)       1/10                      1/1 4    So Required ratio = X : Y = 1/10 : 1/14 = 7:5

Answer: C) Intergovernmental Panel on Climate Change Explanation: IPCC stands for the Intergovernmental Panel on Climate Change. It was established in 1988 by the World Meteorological Organization and the United Nations Environment Programme.     IPCC, with respect to Chartered Accountancy, stands for Integrated Professional Competence Course. This is the second level of the CA course.

Answer: B) 138 Explanation: The gram formula mass of a compound is nothing but the molar mass. The molar mass of K2CO3 (Potassium Carbonate) is given by Atomic weights of individual elements are   K (Potassium) = 39 g C (Carbon) = 12 g O (Oxygen) = 16 g   Hence, that of K2CO3 = 39(2) + 12 + 16(3) = 78 + 12 + 48 = 138.

An atom is the smallest particle of a substance. Chemical substances are divided into two major groups. They are 1. Pure Substances (and) 2. Mixtures.   There are two types of pure substances that are Elements and Compounds.   Elements : An element is a substance that is made up of only one kind of atoms and cannot be broken down into simpler substances by chemical means. Metals and Non- metals come under elements. Examples of elements are Iron, Silver, Gold, Mercury etc.   Compounds : A Compound is a substance that is formed when two or more elements combine chemically. Examples of compounds are Water, Carbon dioxide, methane, vinegar etc.   Mixtures : A Mixture is formed when two or more substances mixed together but not chemically combined. Example: Air.

Answer: D) Nucleus Explanation: In the cell, transcription occurs in the nucleus in the presence of DNA. Terms transcription and translation in biology are generally related to the DNA and its properties. Human cells replicate. In order to do that, they have to produce the same constituents for the new cell that is to be made. The only way to do that is by producing proteins. The proteins are produced in the process that is called protein synthesis. The first step is in the nucleus where a particular gene is being expressed so it enables all protein factors to come and to replicate that part of a chromosome. This is finished when mRNA, the same single-stranded genetic code of a particular gene, is formed. This is transcription. Right after that, the mRNA enters the cytoplasm through nuclear pores. There, it could be translated into proteins by ribosomes. This process is called translation.   Hence, Transcription occurs in the nucleus, whereas translation occurs in the cytoplasm.
