What is cryosurgery? what is nanotechnology? best 10 question


Question 29. What is cryosurgery?

Answer: Cryosurgery is the process of healing abnormal or diseased cells in the body of a person or an organism by applying extra cold or cooling temperatures. (What is cryosurgery?)

Question-28. What is a robot?

A: A robot is a type of computer-controlled automated mechanical system, a human-controlled device or device controlled by a computer program that can perform many difficult and difficult tasks for humans. The robot works on the principle of artificial intelligence. Its operation can be fully automatic, semi-automatic, that is, it can be operated by both man and machine or remotely controlled. The word robot comes from the Slavic word robota which means ‘worker’.

Cryosurgery is also often called cryotherapy. The word cryosurgery comes from the Greek words Cryo (cold as ice) and Surgery (manual work or surgery). Cryosurgery uses liquid nitrogen, nitrous oxide, carbon dioxide, argon, helium, snow, ethyl chloride, and fluorinated hydrocarbons. We can apply these substances to diseased cells in two ways. One of them is with the help of a round tube, which is called a cryoprobe. The other is with the help of cotton. Cryosurgery destroys diseased cells at a temperature of -410.C.(What is cryosurgery?)

Q-30. What is biometrics?

Answer: Biometrics is the method of uniquely identifying a person. In this method, people are uniquely identified through the use of fingerprints, the retina of the eye or iris, hand geometry, face, signature, voice.

Biometrics is derived from the Greek words bio (life) and Metric (measurement).

Biometrics identification methods are divided into two classes. E.g.

  1. Body structure or physiological biometrics and
  2. Biometrics of characteristic or behavioral traits.
  3. Body structure or physiological biometrics and
  4. Biometrics of characteristic or behavioral traits.
  5. Physiological biometrics:
  6. A) DNA b) Fingerprint c) Retina and iris of the eye
  7. D) Hand geometry e) Face recognition etc.
  8. Characteristic or behavioral biometrics:
  9. A) Behavior of a person b) Handwriting or signature
  10. C) human voiced) movement style etc.

Question-31. What is genetic engineering?

Answer: Genetic engineering is the process of separating DNA (Deoxyribose Nucleic Acid) fragments carrying a specific gene from an organism into another organism through biotechnology. Genetic engineering is also called genetic modification. Genetic engineering is mainly about the creation of transgenic plants and animals.

 Question-32. What is nanotechnology /cryosurgery?

A: Nanotechnology is the engineering of making instruments or devices with molecules or atoms. One-tenth of a billionth of a thing is called 1 nano or nanoscale. For example, one-hundredth of a meter is called a 1 nanometer.

Nobel laureate physicist Richard Feynman first introduced the concept of nanotechnology on January 29, 1959. That’s why Richard Feynman is called the father of nanotechnology. There are two processes in nanotechnology.

One is from top to bottom and the other is from top to bottom. In the top-down method, a large object is cut and given a specific shape. And bottom-to-top is to make big things out of small things. Our current electronics is top-down technology. With the help of nanotechnology, the desired object can be created from the components of small objects on the nanometer scale. (What is cryosurgery?)

Question-33. What is bioinformatics /cryosurgery?

A: Bioinformatics is a branch of science that uses computer technology, information theory, and mathematical knowledge to analyze biological data.

The Bangladesh Election Commission has made arrangements to create voter ID cards using bioinformatics technology and store them in the database. (What is cryosurgery?)

As a result of this technology, it is becoming possible to perform various tasks including compiling voter lists, identifying the correct voters, completing the election process properly, preventing fraudulent voting, issuing national identity cards by collecting voters’ pictures, fingerprints, or various information. The software tools used in Bioinformatics are Java, C, C, C.(What is cryosurgery?)

Question-34. What is Ethics?

Answer: Morality is the principle of human actions, behavior, and behavior on the basis of which man can judge the good or bad aspects of work. Morality can lead people to the highest peak of success. Online Business Dictionary. According to com, ethics is – “The basic concepts and fundamental principles of decent human conduct.”

Question-35. What are computer ethics?

Answer: In 1992, the Computer Ethics Institute published a booklet entitled In Pursuit of a “Ten Commandments for Computer Ethics” containing 10 articles or guidelines on computer ethics. These ten guidelines are -1. Do not use the computer to harm others.

  1. Not interfering with another person’s computer work.
  2. Not to interfere with other people’s computer data or files.
  3. Not using computers to steal information.
  4. Do not use the computer to carry false evidence.

. Refrain from copying or purchasing pirated software.

If not free, pay for the software.

. Do not use other people’s computer resources without permission.

. Not claiming the intellectual property of others as one’s own.

  1. Its social impact or negative aspects before creating the software To think about.
  1. Colleagues or others when using the computer for communication
