We should remember that we should consume all necessary nutrients at a correct amount and proportion. this includes the primary food substance carbohydrates, fat and protein. and protective food substance in a small amount, which includes mineral ions ( iron, calcium etc) and vitamins. Also we have to take in enough water (6-8 cups a day) and fibre to prevent deficient diseases and to maintain health.
in addition, note that the amount of food intake varies with age, sex, body status, daily activity etc. For example, teenagers and pregnant women should increase all necessary nutrients intake to ensure proper growth and development of ourselves or the baby.

Answer:
Bilateral symmetry allows for directional motion. The coelom cushions organs allow freedom of motion.
Explanation:
Most animals are bilaterally symmetrical in nature with a line of symmetry dividing their body into two sides left and right sides along-with a “head” in top and “tail” in the bottom. Bilateral symmetry consisting an equal arrangement of symmetry about a vertical plane running from top to bottom.
The coelom is known as the main body cavity present in most animals. It is positioned inside the body to surrounds the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as mollusks, it is undifferentiated. In animals, it helps to allow freedom of motion.
Same genus is more closely related. The farther down the list Phylum-Class-Order-Family-Genus-Species you go, the more closely related are the species in that taxon.
