Computer science which enables the identity of a human being by their traits or characteristics such as fingerprints is called Biometrics authentication. The use of Biometrics authentication allows individuals to be identified based on their human characteristics. In this way, access to certain information can be limited only to an individual or a group of selected people. 

Computer science which enables the identification of a human being by their traits or characteristics such as fingerprints is called biometrics. It is used to figure of identification and access control. The history of biometrics by Josh Ellenbogen and Nitzan Lebovic that biometric is originated in an identificatory system of criminal activity developed by Alphonse Bertillon. 

The correct answer is 1. hydrogen gas and add heat and pressure.

Explanation:

Nuclear fusion is the source of energy of the sun. During nuclear fusion because of the high temperature and pressure in the sun's core the nucleus of two hydrogen gets fused and form helium and the radiant energy is then released which comes to earth.

Therefore scientist are using this natural phenomenon so they are using hydrogen gas and addition heat and temperature so that they can recreate the process of energy production which takes place in the sun. So the correct answer is 1.
