- rush your teeth at least twice a day with a fluoride-containing toothpaste. Preferably, brush after each meal and especially before going to bed.
- Clean between your teeth daily with dental floss or interdental cleaners, such as the Oral-B Interdental Brush, Reach Stim-U-Dent, or Sulcabrush.
- Rinse daily with a fluoride-containing mouthwash. Some rinses also have antiseptic ingredients to help kill bacteria that cause plaque.
- Eat nutritious and balanced meals and limit snacks. Avoid carbohydrates such as candy, pretzels and chips, which can remain on the tooth surface. If sticky foods are eaten, brush your teeth soon afterwards.
- Check with your dentist about use of supplemental fluoride, which strengthens your teeth.
- Ask your dentist about dental sealants (a plastic protective coating) applied to the chewing surfaces of your back teeth (molars) to protect them from decay.

Eg_ respiration in human.
Anaerobic respiration means that respiration in absence of oxygen. (Generally occurs in lower species like bacteria fungi etc..)
Eg_respiration in yeast
Aerobic respiration
C6H12O6+ 6 O2 --- 6 CO2 + 6 H2O + 38ATP
Anaerobic respiration
C6H12O6 ---- 2Lactic acid + 2ATP

Plants function photosynthesis because it brings about the food and energy they need for growth and cellular respiration. For the plants to function photosynthesis, it required light energy, water and carbon dioxide. Light energy can be obtained from the sun, which enters through the chlorophyll present in the leaves. Water is absorbed through the roots and carbon dioxide is absorbed from the atmosphere through pores in the leaves called stomata.

This epidemiological transition is the result of a series of interrelated factors:
- Demographic changes: the reduction in childhood mortality leads to a decrease in fertility rates. As a consequence, a higher percentage of the population reaches the adult age and develops adult-related diseases.
- Changes in risk factors: this includes changes in the prevalence, distribution and/or virulence of pathogenic organisms, environmental changes – frequently linked to human activity- that can cause disease, and social and cultural factors such as lifestyle and diet.
- Modern medicine practices: vaccines are without doubt the greatest public health success in history – every year they avoid 2 to 3 million deaths by diseases such as diphtheria, tetanus and whooping cough, they have allowed the eradication of smallpox and practically that of polio. The discovery of penicillin in the 20th century was another milestone in modern medicine and, ever since, antibiotics have saved hundreds of millions of lives.

he biological process in which food is utilized to produce energy is called respiration. Respiration is necessary for survival of the living beings. A living being cannot survive even for a few seconds, without respiration. During respiration, it is mainly the carbohydrate which is oxidized to produce energy. This can be shown by following equation:
Carbohydrate + Oxygen → Carbon dioxide + Water + Energy
C6H12O6 + 6O2 → 6CO2 + 6H2 + Energy

Percolation property of any material is linked to its porosity. Different soils have different porosity.
Therefore, water percolates differently through different soil.
Percolation rate of water in the soil = Volume of water percolated Time taken for percolation
Whereas water retaining capacity of a soil is described in terms of the amount of water absorbed by a particular type of soil. High water retaining capacity means higer water absorption.
