Answer: B) 12.5% Explanation: Let p% of a day is 3 hrs. We know that a day has 24 hrs. => p x 24/100 = 3 => p = 300/24 => p = 12.5%   Hence, 3 hrs is 12.5% of a day.

Answer: D) Lymphatic system Explanation: Lipoproteins are particles that contain triacylglycerol (TAG), cholesterol, phospholipids and amphipathic proteins called apolipoproteins.   The four major types of lipoproteins are 1. chylomicrons, 2. very low-density lipoprotein (VLDL), 3. low-density lipoprotein (LDL), and 4. high-density lipoprotein (HDL).   Chylomicrons are formed in the endoplasmic reticulum in the absorptive cells (enterocytes) of the small intestine.   The function of these lipoproteins is to deliver energy-rich triacylglycerol (TAG) to cells in the body (pink pathway). TAG is stripped from chylomicrons and VLDL through the action of lipoprotein lipase, an enzyme that is found on the surface of endothelial cells. This enzyme digests the TAG to fatty acids and monoglycerides, which can then diffuse into the cell to be oxidized, or in the case of an adipose cell, to be re-synthesized into TAG and stored in the cell.

Answer: B) 3:2:4 Explanation: Given, y/(x - z) = (y + x)/z = x/yyz = xy + x2 - yz - xz ....(1)Also xy = yx-z ⇒x2 -xz = y2 ....(2)Using (1) and (2), we get yz = xy - yz + y22yz = xy + y22z = x + y Only option (B) satisfies the equation.

Answer: C) Covalent Explanation: Covalent type of bonding joins the two hydrogen atoms. Hydrogen atoms in compounds such as H2 and H2O are joined to the molecule with covalent bonds. This is where electrons are shared between the atoms in order to fill there valence shells.

Answer: B) 8 Explanation: Given for year = 70000 => 365 days = 70000 => 365 x 24 hours = 70000 =>   1 hour = ? 70000/365x24 = 7.990 = 8

Answer: D) Peat Explanation: The first of the four stages of coal formation is lignite coal.   There are four stages of coal formation:   1. Peat,   2. Lignite,   3. Bituminous and   4. Anthracite. The bacteria has removed a large portion of the other constituents of the plant matter and left around 25 to 34 percent.
