Ozone filters the UV radiation (emitting by Sun). By doing that, it keeps our environment safe & healthy.
Hope this helps!
We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
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.
