Answer:
Ethics refers to some set of rule and regulations or principles, that ensure the right conduct in a definite professional or academic environment.
When we talk about lab ethics, there are a set of principles which a scientist need to follow to demonstrate excellent lab ethics.While working in laboratory a scientist must make sure that ethical standards are a priority of them. Here we will discuss few of those:
- A scientist should never manipulate the data and results just to make them in accordance with the previously reported studies.
- Scientist should properly document every protocol and process and take special care that no changes are made in experiment due to environmental influences that can affect the reliability of results.
- Scientist should always report the results and processes which he performed and never report work without actually doing it.
- Scientist should never omit some part of the experiment or compromise the data or results of experiment.
- Scientist should never manipulate the calculations.
- Every process or step that is part of a scientist's experimentation should be conducted before the finalization of the results and not perform procedure after results are made.
- Scientist should replicate his experimentation at least three times to make sure that what he is reporting is based on facts and not just error in experimentation.
- Scientist should never report self made information just to validate or proof his work.

Answer:
The correct answer will be-
1. Pupil
2. Retina.
Explanation:
Organisms are able to see the world around them thorugh the sense organs called the eyes.
The structure of eye contains various modified structure which include the membranes and the attached muscles.
When light enters the light through the dome-shaped structure called cornea which contains the convex lens converges the light and light enters the hole called pupil through which light enters and strikes or get focused on the retina present at the back of the eye.
The pupil is attached to the ciliary muscles which dilate and contracts in the response of the intensity of light as during high light intensity, the pupil constricts whereas during the low light intensity the pupil dilates to allow the maximum amount of light.
Thus, pupil and retina is the correct answer.
