NEET BIOLOGY

Detailed explanation-1: -Three of the major characteristics utilized to categorize organisms are cell structure, mode of food, and cellularity. So The correct option is ‘C’.

Detailed explanation-2: -Taxonomy is the study of classifying and naming organisms. Modern taxonomy is based upon natural classification methods, which are based on genetic similarity and evolutionary relationships. These methods involve measuring the degree of genetic similarity between two or more organisms by comparing their DNA sequences.

Detailed explanation-3: -Scientists classify organisms in different ways. Scientists organize the living world using a process called taxonomy, which is the science of classifying organisms based on shared structures, functions, and relationships to other organisms. For example, organisms can be classified based on their cellular structure.

Detailed explanation-4: -To classify organisms, scientists use similarities and differences among species. Sometimes these differences are easy to see, such as whether an animal has fur, feathers, or scales. Other times, seeing the differ-ences requires special laboratory equipment, such as equipment to study DNA.
