50's is the largest sub unit because it have one large RNA with 23rRNA and one small RNA with 5s RNA and also 35 different proteins in them and these are mostly in a single copy
The diaphragm, located below the lungs, is the major muscle of respiration. It is a large, dome-shaped muscle that contracts rhythmically and continuously, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to i... morets dome like shape, and air is forced out of the lungs. Diaphragm contracts, moves down and flattens during inhalation and diaphragm relaxes and curves upwards during exhalation. So, when diaphragm of man is completely dome shaped, it shows that beginning of expiration and end of inspiration.
Understand the mechanism, keep the concept clear and practice as much as possible. the book of DK singh is very good and one is MS Chauhan, both these book are awasome u will get a lot of profit.
By convex lens formula:1/v - 1/u =1/f v = f*u/u-f ; 200*200*10³/200-200*10³ (2km=200*10³cm) v= 200*10³/999 in magnification, {v/u} = {h'/h} so, 200*10³/999*200*10³ h'=5000/999=5.005 h' is nearly equal to 5cm.
The initial agreement was designed to reduce the production and consumption of several types of CFCs and halons to 80 percent of 1986 levels by 1994 and 50 percent of 1986 levels by 1999. The protocol went into effect on Jan. 1, 1989...Thus, option A is right ans..
