How does eye location best represent the relationship between structure and

A location of a eye can be a structural adaptation among organisms. The eye location can help organisms to perform different functions in an ecosystem. There are two types of eye locations : monocular and binocular. The eye location affects the vision characteristics of living organisms hence, directly affects functions like searching of food and shelter, capturing of prey, protection against predator and other important ecological functions. Monocular eye location promotes monoclonal vision, the eyes are present on the sides of the head provides wider field view. This provides less depth perception because of wider field observation. Binocular eye location promotes binocular vision, the eyes are located on front of the head of the organism provides higher accuracy and depth perceptions. Monocular eyes are found in some herbivores, allow them to see predators from both sides of their head and hence, prevent them from being caught by predators. Binocular eyes are present in some  carnivores, allows them to observe and hunt prey.  

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.
