Ultrasonic or high energy frequency wave-object interaction breaks down stone particles and cancerous cells in human body.
Explanation:
Kidney stones and Cancer in human tissues are a common medical problem. Scientist through their cutting-edge research has found a novel solution to this enigma. They have utilised the property of high energy acoustic waves or sound waves to target kidney stones to destroy them.
The procedure is performed from both inside the body as well as outside the body. The process is simple high energy ultrasonic waves are administered to the stones after locating them. The stone after absorbing the energy gets broken into pieces. Using suction and irrigation methods, stone fragments are removed from the body
Answer:
D. Narrow his focus
Explanation:
In writing a research,a topic has to be selected first. This could be provided by a supervisor or the individual, on a topic he is interested in. After forming a topic, many general questions should be formed. This would provide a wide view from which to assess the topic.
Too many general questions ought to be further narrowed into more specific questions. It is important that the researcher chose a topic on which information could be found easily. This would make it easier for the questions to be easily narrowed and not too broad. He should also avoid open ended questions, that is yes or no questions, so as to make the information more meaningful.
