Q. Explain the process of budding with an example.
Posted by: Chetan45dude
A. Budding is a form of asexual reproduction where a bud/ outgrowth from the end or side of the parent organism emerges and develops into a new organism. This is seen in fungi, hydra as well as in plants. Usually, the protrusion stays attached to the primary organism for a while, before getting detached.
The new organism is naturally genetically identical to the parent. When yeast buds, one cell divides into two cells. When a sponge buds, a part of the parent sponge falls off and starts to grow into a new sponge. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and when fully mature, detach from the parent body and become new individuals.

Q. If 2 tan a =3 tan b, then prove that tan(a-b)=sin 2b/ (5-cos2b).
Posted by: Desi MJ
A. Let us denote a = A and ß = B.
2tanA = 3tanB Þ tanA = 3/2 tanB
tan(A-B) = (tanA - tanB) / ( 1+tanAtanB) = 1/2 tanB / ( 1+3/2 tan2B)
Put tanB = sinB / cosB and simplify:
= sinBcosB / (2cos2B + 3sin2B) = 2sinBcosB / (4cos2B + 6sin2B) = sin2B / (4 +2sin2B)
=sin2B / (4 - (1-2sin2B) +1)
=sin2B / (5 - cos2B)
