Explanation:

1. Esthetics is the study of maintaining and improving the skin. Onychology is the study of nails, public hygiene is about community cleanliness, and personal hygiene is about an individual's cleanliness.
2. Most people need 6 - 8 hours of sleep to function properly and avoid fatigue. 1 - 2 or 3 - 4 hours are too little, and 9 - 12 hours are more than most need.
3. Exercise stimulates blood circulation. Watching TV, reading a book, and listening to music are more sedentary activities.
4. Avoiding getting organized does not help manage stress. Asking for help, getting regular exercise, and practicing deep breathing are stress - management techniques.
5. The energy in food is measured in calories. Degrees measure temperature, and fat and protein content are components of food, not energy measures.
6. Retinol is a topical form of vitamin A that promotes cell turnover and increases skin elasticity. Calciferol is vitamin D, beta - carotene is a precursor to vitamin A but not the topical form, and ascorbic acid is vitamin C.
7. Calcium builds and strengthens teeth and bones. Iron is for blood, sodium for fluid balance, and potassium for nerve and muscle function.
8. Personal hygiene is an individual's system for maintaining cleanliness and health. Nutrition is about food, public hygiene is community - based, and public sanitation is related to waste disposal.
9. Lack of sleep is not good for healthy, glowing skin. Rest, exercise, and good nutrition are beneficial.
