A recessive gene is simply a gene that is not EXPRESSED! Recessive and dominant do not have anything to do with how "common" they are. Dominant just means it is expressed more often.
Recessive would be for example blue eyes or blonde hair.

The macromolecule must be starch.
Explanation:
Starch is a polymer of Glucose joined by glycosydic bond.
Starch is the main energy storage substance in green plants.
Starches react with iodine and give a bluish black or black color and thus iodine test is considered as a confirmatory test for starches.
In this experiment ,the solution turns very dark black on addition of iodine so we can be sure that the solution contained starch.
The correct choice is velocity=distance/time of v=d/t
