<u>Answer:</u>
<em>The biologists clarify these similarities as a homologous pair. This is based on the principle of convergent evolution.</em>
<u>Explanation:</u>
<em>Convergent evolution</em> is understood by the phenomenon of development of similar organs in different species in different period. Those<em> homologous pair </em>have same structure but can have different function in the different <em>species of organism. </em>
The bone of human arms, wings of the bat and dolphin flippers contain many of same bones which have developed from the same embryo tissue but the function for each is <em>different in different species.</em>
Answer: a.The individual always has the biometric in their possession.
Explanation:
Biometrics is a term that is used for the technology that is used to measure the bodily features and making a calculation on that basis. It is a method that can be used for the purpose of identification and authentication for the purpose of access control.
Among the given options, a.The individual always has the biometric in their possession. is the correct option. This is because of the fact that biometric measurements can be based upon physical characteristics such as fingerprints, retinal scans, and facial recognition. These features are common and unique to every human being. Hence, biometric system can be advantageous for physical access control.
<h3><u>Answer;</u></h3>
