Deep fried foods are carcinogenic because they are rich in fats.

Type 2 diabetes is the most common form of diabetes.

• If you have type 1 diabetes your body does not release insulin.

• If you have type 2 diabetes your body does not use insulin properly.

This rise in blood glucose causes insulin to be released from the pancreas so glucose can move inside the cells and be used. As glucose moves inside the cells, the amount of glucose in the bloodstream returns to normal and insulin release slows down.

Plants grow in size both in height and in girth. Enlargement of cells already present cannnot contribute much to the growth. Only addition of more and more cells could increase the size of the plant considerably.

Mitochondria is absent in Bacteria as well as in Blue Green Algae. They are seen in eukaryotic cells for respiration purpose.

Spongy, porous bone tissue is also called cancellous bone.

Cancellous bone is found in bones that aren't generally under significant stress like in the shoulder blades, ribs, parts of the skull, and at the ends of long bones.

Gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism.

In short it is a piece or segment of chromosome.

Genes undergo mutation when their DNA sequence changes. 

DNA is made of nucleotides. And these Nucleotides are made of a pentose sugar deoxyribose, a phosphate, and a nitrogen-containing bases.

Hence, the given statement 'Nucleotides are made of a pentose only' is FALSE.
