Answer :
Explanation :

The United States government has 3 branches, which all serve an important role in running the government and keeping our system of laws in place.   1. The legislative branch 2. The executive branch  3. The judicial branch   The legislative branch makes the laws while the executive branch enforces these laws.  The judicial branch is a system of courts that applies the laws.   Both the federal government and each of the 5 states have individual judicial branches which all serve this purpose.   For example ::  If the federal government were like a basketball game, the judicial branch is much like the referee that helps settle disputes. The executive branch and the legislative branch are often like the players in the game trying to score points against each other, and the judicial branch is there to clarify the rules and make sure each side is acting fairly.

Answer : 2. "8 %"
Explanation :

Answer: B) 8 % Explanation: Let the price of 1 litre of diesel be Rs.x and let Karthik initially buy 'y' litres of diesel. Therefore, he would have spent Rs. xy on diesel. When the price of diesel increases by 25%, the new price per litre of diesel is 1.25x. Karthik intends to increase the amount he spends on diesel by 15%.i.e., he is willing to spend xy + 15% of xy = 1.15xy Let the new quantity of diesel that he can get be 'q'.Then, 1.25x x q = 1.15xyOr q = (1.15/1.25)y = 0.92y. As the new quantity that he can buy is 0.92y, he gets 0.08y lesser than what he used to get earlier. Or a reduction of 8%.

Q: What is the meaning of the four colour dots in the news paper? 1791 0

  • Show AnswerHide Answer

Answer :
Explanation :

If you read newspaper daily, then you may be aware of the four coloured dots on the corner of the newspaper.    The four dots CMYK — blue (Cyan), pink (Magenta), Yellow and black (Kalio) are registration marks used during printing to help ensure the print is aligned properly. Any colour can be obtained by adding the correct proportion of these four colours.   CMYK is used as a base for the colours used in printing newspapers, and these four colours are often printed on the paper in either a heart, dot, or square shape.   To print an image, the plates of all these colours are laid out on a page separately and lined up in the same spot while printing. If those four dots are blur or you find the colours overlapping on the image it means the printing is not good. To print an accurate and perfect image, the colors and shape must be arranged precisely and must be claear sharp in order to get the best output.   That's why CMYK is also called registration mark. As physically checking all the pages of the paper is not possible for a printer who prints number of news papers daily, he just checks these dots.

Answer :
Explanation :

Bile contains bile acids, which are critical for digestion and absorption of fats in the small intestine. Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances, such as the vitamins A, D, E, and K. Besides its digestive function, many waste products, including bilirubin, a byproduct of red blood cells recycled by the liver are eliminated from the body by secretion into bile and elimination in feces.
