Ans → Stereoisomer
Explanation →
Q. Process that differentiates or separates solid particles according to their size using a meshed or perfo- rated device.
Ans → sieving
Explanation →

Ans → catalyst
Explanation →
Q. A chemical processes in which the proportion of more electronegative substituents is decreased, or the charge is made more negative, or the oxidation number is lowered.
Ans → reduction
Explanation →
Q. Molecules that exist only during a chemical reaction; not before or after the reaction.
Ans → intermediate
Explanation →
Q. A type of endocytosis in which extracellular ligands are targeted to specific cells through their binding to specific cell surface receptors
Ans → receptor-mediated endocytosis
Explanation →
Q. The glycosidic bonds at the branching points in the structure of starch are
