Expln:- Eclipses do not occur every month during a new moon or a full moon. This is because the orbit of the moon is titled by about five degrees with respect to the earth’s orbit, so that usually the moon passes slightly above/below the line between the sun and the earth. Thus at most new and full moons, the shadows miss their….

Expln:- If you cut a linear DNA you will get one more fragment than you have restriction endonuclease sites. When cutting circular DNA, you get the same number of fragments as there are RE sites…..
(i) Let x = 5
(ii) then x2-25 = x-5
(iii) (x-5) (x+5) = x-5
(iv) x + 5 = 1 [cancelling (x-5) from both sides] (v) 10 = 1 [Putting x=5]
Which of the above is the wrong step ?
1. (i) 2. (ii) to (iii) 3.(iii) to (iv) 4.(iv) to (v)
x2 = 25
Ie; 25 – 25 = 0
X = 5
Ie; 5 – 5 = 0

Expln:- Many of the original theories of the formation of our solar system postulated that a proto-planetary disk of dust and gas that surrounded our sun some 4.5 billion years ago, and this disk rotated around the sun, just as we orbit the same star now. The most popular theory put forth the idea that within this spinning disk, the heavier, metallic-elements (silicates and so forth) would fall in towards the star, and the lighter elements, mainly Hydrogen and Helium….
