Answer:
Taking the example of hand geometry, i-e fingerprints for verification, it is very easy to implement due to the relatively small size of the sensors. As with all digitally stored biometric data, there are risks of data theft.
Explanation:
Fingerprint sensors use scanners to scan the geometry of the patterns on the skin, usually the fingertips. These patterns are unique to each individual to a very high degree, roughly 1:64,000,000 pairs of fingerprints have the chance of being identical. These sensors are relatively easy to install, are cheap, and very user friendly. This makes this technique a very effective method.
Since the data collected by the scanners is almost always stored digitally in a device which is connected to the internet or has access points, there is always the threat of data theft which can result in identity theft and possible fraudulent activities.

Answer:
The dependent variable - the cholesterol level
Independent variables are the exercise and the drug.
Explanation:
A variable is a factor that can be modified or change. It is the factor that can be measured, altered, controlled in research or the experiment. It can be dependent or independent of their effect.
The independent variable is the factor of the experiment that controlled or manipulated by the researcher and it is considered to have a direct effect on the dependent variable whereas the dependent variable is being checked or tested.
So, in this experiment, the variable that is being tested is the cholesterol level that means it is a dependent variable. The independent variable here is exercise and drug as they manipulate and have an effect on the direct variable.
Thus, the correct answer is -
The dependent variable -the cholesterol level and
independent variables - exercise and the drug.
