Passwords, tokens, and fingerprint scans are all examples of Authentication.
We use passwords, tokens and even fingerprints since they can be unique identifications and are usually seen as more secure.
In the above options, fingerprints are seen as the most secure form of authentication since everyone has unique fingerprints.
One of the earliest forms of authentication were time cards used as early as the 1950s and even unique keys and stamps used by early civilizations.

The correct answer is:
Includes at least two groups, one of which does not receive the experimental treatment. (B)
Explanation:
A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.
<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
I think in this case Bryophytes are more similar to ancestral green algae than are vascular plants. These plants lack a vascular system for transporting water and minerals, Unlike angiosperms they do not produce flowers, fruits, or seeds. They also lack true leaves, roots, and . stems, They appear as small, green mats of vegetation found i damp habitats. Lack of vascular tissues means that these plants must remain in moist environments.
