[Hint : (a) Catalyst is a substance that alters the rate of reaction without consuming itself in the reaction. Ezymes are biocatalysts, they are highly specificthan catalysts.
(b) Promoters enhance the activity of a catalyst while poisons decrease the activity of catalysts.]
Biological Catalysts:
Enzymes: Enzymes are soluble protein molecules that can speed up chemical reactions in cells.
In living organisms, enzymes catalyze numerous biochemical reactions that sustain life and are involved in growth and reproductive functions.

Let two A.P's have the first terms a , a' and common difference d.
Given that difference between their 100th term is 100.
then a + 99d - a' - 99d = 100

Asexual reproduction
Sexual reproduction
(a) Involves only one parent
(b) Gametes are not produced
(c) No fertilization and zygote formation
(d) Meiosis does not occur at any time during reproduction
(i) Often involves two parents
(ii) Gametes...

[Hint : Heterogeneous catalyst, activity and selectivity of catalysts. Example, Hydrogenation of unsaturated hydrocarbons in presence of Raney Ni or any other
example.]
(i) The catalytic activity of transition metals is attributed to the following reasons:
(a) Because of their variable oxidation states transition metals form unstable intermediate compounds and provide a new path...
