What is raw food diet?

The raw food diet is an eating plan that involves fresh fruits, vegetables, nuts, seeds and sprouts that are not cooked. Eating raw foods in their natural form means retaining all the vital nutrients that the food is designed for. Raw foodists eat foods that are not heated above 120-degrees. Foods that are prepared under this temperature is still considered a “raw” food because the nutrients and enzymes have not been disturbed. 

 

Why focusing on health education is an appropriate measure?

Because it addresses one underlying cause of the problem. It is clear that there is a connection between what people know about nutrition and their eating habits. For example, children who have learned in school about the need to have a varied diet with plenty of vitamins tend to eat more healthily. In contrast, people who have not had this education still eat too much junk food and as a result suffer from diabetes and other diseases.

 

What are disease detectives?

Disease detectives look at clues from tiny germs to unravel the mystery of disease. They can increase our ability to detect and respond to threats. Disease detectives are our “boots on the ground,” helping track, contain, and eliminate outbreaks before they become epidemics. When health threats strike, trained disease detectives investigate and use what they’ve learned to prevent people from getting sick. They communicate crucial information quickly about health problems in a community, including infectious and noncommunicable diseases and environmental hazards.

 

What are the uses of DNA in technology? Give an example.

Genetic engineering

Methods have been developed to purify DNA from organisms, such as phenol-chloroform extraction, and to manipulate it in the laboratory, such as restriction digest and the polymerase chain reaction.

Modern biology and biochemistry make intensive use of these techniques in recombinant DNA technology. Recombinant DNA is a man-made DNA sequence that has been assembled from other DNA sequences. They can be transformed into organisms in the form of plasmids or in the appropriate format, by using a viral vector. The genetically modified organisms produced can be used to produce products such as recombinant proteins, used in medical research, or be grown in agriculture.
