Answer : 4. "Ounce"
Explanation :

Answer: D) Ounce Explanation: Yard is to Inch as Quart is to Ounce. Because Yard and Inch are units of measurement Where Yard is larger than Inch i.e, 1 Yard = 36 Inches. So, here Quart and Ounce are also units of measurement where Quart is larger than Ounce i.e, 1 Quart = 32 Ounces. Gallon is not correct because Gallon is larger than Quart and Milk and Liquid are not units of measurement. So, Ounce is correct.

Answer : 1. "1 : 3"
Explanation :

Answer: A) 1 : 3 Explanation: Let the speed of the boat in still water is 'w' Speed of the current is 'c' Let the distance between two places is 'd' According to the question, motorboat takes half time to cover a certain distance downstream than upstream. dw+c = 12dw-c => 2w - 2c = w + c => w = 3c => c : w = 1 : 3   Hence, the ratio between rate of current(c) and rate of boat in still water(w) = 1 : 3

Answer : 3. "9"
Explanation :

Answer: C) 9 Explanation: Given   6 = 3 => Number of letters in SIX = 3   12 = 6 => Number of letters in TWELVE = 6   14 = 8 => Number of letters in FOURTEEN = 8   Similarly,   22 = 9 => Number of letters in TWENTY TWO = 9           Therefore, 22 = 9.

Answer : 1. "6CO2 + 6H2O -----> C6H12O6 + 6O2"
Explanation :

Answer: A) 6CO2 + 6H2O -----> C6H12O6 + 6O2 Explanation: Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.   Photosynthesis can be represented using a chemical equation.   The overall balanced equation is                 6CO2 +  6H2O   →Sunlight    C6H12O6   +   6O2Source of Carbon & Oxygen  + Source of Electrons & Hydrogen + Energy that drives Photosynthesis             ----> Sugar + Gas produced by splitting water.   Where  CO2 = carbon dioxide  H2O = waterC6H12O6 = glucose  O2 = oxygen.

Answer : 2. "Band width"
Explanation :

Answer: B) Band width Explanation: The path that data takes from source to destination is called a Channel. A channel is a communication medium. A channel has a certain capacity for transmitting information.    The "capacity" of a channel is the theoretical upper-limit to the bit rate over a given channel that will result in negligible errors. Channel capacity is often measured by its Bandwidth in Hz or its data rate in bits per second.
