    Rod cells are photoreceptor cells in the retina of the eye that can function in less intense light than the other type of visual photoreceptor, cone cells. Rods are usually found concentrated at the outer edges of the retina and are used in peripheral vision. On average, there are approximately 90 million rod cells in the human retina.[1] Rod cells are more sensitive than cone cells and are almost entirely responsible for night vision. However, rods have little role in color vision, which is the main reason why colors are much less apparent in dim light, and not at all at night.

    Cone cells, or cones, are of three types of photoreceptor cells in the retina of mammalian eyes (e.g. the human eye). They are responsible for color vision and function best in relatively bright light, as opposed to rod cells, which work better in dim light. Cone cells are densely packed in the fovea centralis, a 0.3 mm diameter rod-free area with very thin, densely packed cones which quickly reduce in number towards the periphery of the retina. There are about six to seven million cones in a human eye and are most concentrated towards the macula.

    A group of stars which resembles certain shape is called a constellation. Human beings have an innate ability to recognize shapes and faces even in formless things; like clouds, smoke, etc. This ability of human beings has given rise to various constellations. Different constellations may have different names in various cultures. There are twelve signs of zodiac, viz. Aries, Taurus, Gemini, Cancer, Virgo, Leo, Libra, Scorpio, Capricorn, Sagittarius, Aquarius and Pisces. There are numerous other constellations, e.g. Great Bear, Cassiopeia, Ursa Minor, Orion, etc.

    Friction is said to be a necessary evil because it is useful as well as harmful. friction helps us to walk, write, hold things, lift objects. So it is necessary in our lives. Without friction many essential processes can not be done. On the other hand, it is also unecessary at times. it sometimes results in loss of energy, wear and tear of parts of machinery, due to which it  also damages things. so it is an essential evil.

    Spiracles are openings on the surface of some animals, which usually lead to respiratory systems. Insects like cockriach, housefly and moth have a special network of tubes called trachea. ... Through the spiracles air comes in and goes out of the body. Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss.
