X is cilia which are needed for moving upward mucus,while the cell below it is goblet cell and it secretes mucus,so ans is b.

Got 35 too.
Can you explain the last question?

It shows both variation as there is continuous trend present,but there is also a gap indicating a discontinuous.
Mind explaining Q20 of w12qp12.Shouldnt it be D?And Q30,shouldnt it be A as proteins are composed of amino acids,and they are in more number since all amino acids may be present but a protein is strictly made of amino acids.And Q33 also cuz the cells are 2 and they fuse to make 1 and it reduces to form 4 so shouldnt chromosome number be a quarter of one in big cell?
