Answer 2

Explanation:

2) Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules.

3) So, when we switch on a bulb, electrons in the tungsten wire get excited and release energy in terms of photons. In all, there is just a temporary rise in temperature and release energy in the form of light. ... Hence, glowing of a bulb is a physical type of change.

4) Germination is the process by which an organism grows from a seed or spore. The term is applied to the sprouting of a seedling from a seed of an angiosperm or gymnosperm, the growth of a
