Osmosis is the process in which water molecules move from a region of higher water potential to a region of lower potential down a water potential gradient across a partially permeable membrane. It doen't requires any additional energy to do this work.  So, Osmosis is a Passive.   Active and passive transport processes are two ways molecules and other materials move in and out of cells and cross intracellular membranes. 1. Active transport is the movement of molecules or ions against a concentration gradient (from an area of lower to higher concentration), which does not ordinarily occur, so enzymes and energy are required. 2. Passive transport is the movement of molecules or ions from an area of higher to lower concentration. Passive transport occurs because of the entropy of the system, so additional energy isn't required for it to occur. 3. Active transport requires energy to proceed, while passive transport does not require the input of extra energy to occur.

Pinaka is a multi barrel rocket launcher developed by the Defence Research and Development Organisation (DRDO) for the Indian Army. 2. The system has a maximum range of 40 km for Mark-I and 75 km for Mark-II, and can fire a salvo of 12 rockets in 44 seconds. 3. The system is mounted on a Tatra truck for mobility. 4. Actually, the meaning of Pinaka is Shiv Dhanush.

Answer: A) Rs. 6000 Explanation: Let the sum invested be Rs. P Let the rate of interest be R% per annum => Interest earned for 5 years = (P x 5 x R/100) = PR/20 Now, given that the interest earned increased by Rs. 600 if the Rate increased to (R+2)% => SI = (P x 5 x (R+2))/100 = PR/20 + 10P/100 Hence, PR/20 + 10P/100 = PR/20 + 600 => P = 6000 Therefore, the sum invested is Rs. 6000

Answer: C) Zn Explanation: In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic bonds. Metals are opaque, lustrous elements that are good conductors of heat and electricity. Most metals are malleable and ductile and are, in general, denser than the other elemental substances.   Examples of metals are aluminium, copper, iron, tin, gold, lead, silver, titanium, uranium, and zinc.   Here Se - Selenium is an element but is not a metal, S - Sulphur is not a metal and I - Iodine is also not a metal.   Hence, Zn - Zinc is the only metal in the given options.
