29) H2O is an example of a polar covalent bond. In a H2O molecule electrons are unequally shared, with the oxygen atom. Since electrons spend more time with the oxygen atom and that is why it carries a partial negative charge.
So option (c) is the correct answer.
30)
Hydro = water
Philic = loving
Phobic= hating
So, Hydrophilic = Water loving
Hydrophobic = Water hating
Option (a) is the correct answer.
31) The body uses cholesterol to build the structure of cell membranes. It also makes hormones like oestrogen, testosterone and adrenal hormones.
So option (e) is the correct one.
32) When the water freezes then water molecules slowe down and their attractions arrange them in fixed positions as a result these molecules freeze in a hexagonal pattern and go further apart than they were in liquid form.
So option (a) is the correct one.
