    In a group of cows and chickens, the number of legs was 14 more than twice the number of heads. The number of cows was: (a) 5, (b) 7, (c) 10, (d) 12, (e) 14 Solution: Let the number of cows be x and their legs be 4x. Let the number of chicken be y and their legs be 2x. Total number of legs = 4x + 2y. Total number of heads = x + y. The number of legs was 14 more than twice the number of heads. Therefore, 2 × (x + y) + 14 = 4x + 2y. or, 2x + 2y + 14 = 4x + 2y. or, 2x + 14 = 4x [subtracting 2y from both sides]. or, 14 = 4x – 2x [subtracting 2x from both sides]. or, 14 = 2x. or, x = 7 [dividing by 2 on both sides]. Therefore, the number of cows = 7. Answer: (b)

    Digestion is the process of breaking the insoluble and large food molecules into soluble and minute molecules. In amoeba, the food vacuoles are transported deeper into the cell and with the help of the digestive enzymes, the large insoluble particles are broken down to the simplest molecules.

    • A cell is living whereas a brick is non-living.
    • A cell exchanges materials with its neighbouring cells and environment. No such exchange occurs between the bricks.
    • A cell requires a continuous source of energy for its functioning. Bricks do not need energy.
    • A cell has a specific life span. They will grow, reproduce and die. No such processes are shown by bricks.

In miles per hour, light speed is, well, a lot: about 670,616,629 mph.

    Menstruation, or period, is normal vaginal bleeding that occurs as part of a woman's monthly cycle. Every month, your body prepares for pregnancy. If no pregnancy occurs, the uterus, or womb, sheds its lining. ... It passes out of the body through the ******. The ovaries release the female hormones estrogen and progesterone . These hormones cause the lining of the uterus (or womb) to build up. The built-up lining is ready for a fertilized egg to attach to and start developing. If there is no fertilized egg, the lining breaks down and bleeds.

    Nosebleeds can be caused by being up in a very high altitude. As you climb higher, the amount of oxygen in the air decreases. This makes the air thinner and dryer, which can in turn cause the inside of your nose to crack and bleed.

    We know that friction is the resisting force that exists between any two surfaces in the opposite direction of the motion. Friction is between solid surface, layers of fluid, and also between any two materials. If there is no friction then most of the tasks such as walking on the road, writing on a board, sliding of the table, etc would become difficult. Therefore, friction is one of important forces that is needed for a smooth life.
