What does biometrics analyze?

Biometrics analyzes unique physical or behavioral characteristics, making it an essential tool for identification and authentication. This can include attributes such as fingerprints, facial recognition, iris patterns, voice recognition, and even behavioral traits like typing speed or walking patterns. The primary purpose of biometrics is to provide security and verify individuals based on these distinct traits, which remain relatively consistent over time.

The other options, while related to health or personal identification in some way, do not fall under the scope of biometrics. Nutritional intakes pertain to dietary habits and health rather than individual identification. Bone density measurements focus on assessing skeletal health and do not serve as a means of identification. Genetic coding and sequences deal with biological data related to DNA but do not provide the physical or behavioral traits that biometrics leverages for identification purposes. Therefore, the correct choice highlights the specific nature of biometrics in assessing characteristics that uniquely define individuals.
