Answer and Explanation:
- Ingestion of foods and liquids
- Mechanical processing of food materials and liquids
- Warming the body with heat released from the digestive organs as they process food.
Digestion is the breakdown of food substances by enzymes to simpler compounds that can be absorbed. Digestion begins in the mouth. Once food is ingested in the mouth, it is chewed and broken into small particles suitable for swallowing. Mechanical procesing of food is through the wave-like contractions of the muscular walls of the alimentary canal called peristalsis. Churn and pound food mixing it with digestive enzymes.
After digestion, absorption and assimilation, the final product is oxidized to provide energy to the body.
Answer:

Explanation:
Genotype, the genetic constitution of an organism. The genotype determines the hereditary potentials and limitations of an individual from embryonic formation through adulthood. Among organisms that reproduce sexually, an individual’s genotype comprises the entire complex of genes inherited from both parents. It can be demonstrated mathematically that sexual reproduction virtually guarantees that each individual will have a unique genotype (except for those individuals, such as identical twins, who are derived from the same fertilized egg).
The main storage reservoir for water on earth is ground water
Explanation:
Lichen is the best species to determine the pollution of air. They are highly sensitive to pollution and will barely be found growing on trees or rock in regions where the air has been polluted.
Worms are also a good indicators of pollution in the soil. Polluted soils will have very few to no worms.
Small invertebrates like the Caddisfly are used to determine pollution of water. They are very sensitive to water pollution and cannot be found in polluted waters. In addition toads and frogs are rare in polluted waters and air.

So the important factors are air pressure, temperature, and humidity. The base it is normal and easy to breathe. As you go towards the summit the temperature drops, air density and pressure is low; air is thin, and the humidity is also low. This results in hyperventilation as the air pressure is low. Also there is a chance of getting Hypoxia. The environment is harsh.
