Answer: The part of DNA that the teacher was modelling would be the backbone of DNA.
Explanation:
The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.
The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.
The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.
This backbone part was part that the teacher was making as a model by using two coiled springs.

Answer: Capillaries are tiny branched blood vessels that joins the arteries to the veins
Explanation:

They have the following functions:
- They have tiny walls and are tiny enough to penetrate to all parts of the body
- The thin walls help them diffuse oxygen, nutrients and waste products between cells and the blood.
