v1v2=r12×h1r22×h2 

d1 = 2r1 and d2 = 2r2 are diameters

You cannot see a microorganisms without using a Microscope. You also cannot taste or smell microorganisms such as bacteria in contaminated food.

3/15 + 4/16 + x/24 = 1

⇒x=1315

The given series is 9 81 ? 6561 59049

It follows a pattern that

9

81 = 9 x 9

729 = 9 x 9 x 9

6561 = 9 x 9 x 9 x 9

59049 = 9 x 9 x 9 x 9 x 9

Hence, the missing number in the series is 729.

Given A,B,C can complete a work in 15,20 and 30 respectively.

The total work is given by the LCM of 15, 20, 30 i.e, 60.

A's 1 day work = 60/15 = 4 units

B's 1 day work = 60/20 = 3 units

C's 1 day work = 60/30 = 2 units

(A + B + C) worked for 2 days = (4 + 3 + 2) 2 = 18 units

 Let B + C worked for x days = (3 + 2) x = 5x units

C worked for 2 days = 2 x 2 = 4 units

Then, 18 + 5x + 4 = 60

22 + 5x = 60

5x = 38

x = 7.6

Therefore, total number of days taken to complete the work = 2 + 7.6 + 2 = 11.6 = 11 3/5 days.

Enzymes are protein macromolecules. Enzymes are almost always made of proteins only. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. There are 20 different common amino acids that make up proteins like enzymes. Of these, nine amino acids are essential, which means you must get them from your diet.

Enzymes catalyze chemical reactions in biological systems. This means that they speed up the rate of the reaction.
