2nd one is the right answer
The sensing component of the feedback system that senses the changes in the environment and generates nerve impulse is known as a receptor.
<h3>What are nerve receptors?</h3>
Nerve receptors can be defined as biological structures capable of converting external/internal stimuli to electrical impulses.
Nerve receptors include different types of cellular structures located in eyes, skin, mouth, nose, etc.
In conclusion, the sensing component of the feedback system that senses the changes in the environment and generates nerve impulse is known as a receptor.

Answer:
To find the extinct species and their divergence of characters can be studied using molecular genetic techniques.
Explanation:
- Paleontology is the study of ancient species and their remaining that were found millions of years ago. These species extinction can be found and manipulated to find out the origin or divergence of species from their origin
- The samples of these species may contains their remains that help the biologist to isolate and analyze their protein or DNA. when the DNA is isolated their sequences can be generated using molecular biology techniques.
- When the sequences are identified by advanced molecular biology techniques, the existence and similarities of different species due to their convergence or divergence can be identified.
- By identifying the convergence or divergence the characteristics, evolutionary change in behavior, variation in appearance can be studied.
- By using these techniques, biologist have found that <em>homo sapiens</em> are 99% have their similarities with chimpanzee
- Thus, using genetics in paleontology helps us to understand adaptation a species is changing according to the evolutionary changes.
Answer:
The inputs can be material, such as the silicon used in the computer chips in a phone, or energy, which is used, for example, to manufacture and operate a phone. Outputs can be usable products or wastes, which must be disposed or recycled. A life cycle analysis of a cell phone also includes an analysis of its individual parts.
