Answer:
The scientists should look for samples that do not have a nucleus or cell membrane when viewed under the microscope.
Step-by-step explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include; nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.
Generally, all nonliving organisms or things do not have life or cells in them and as such are devoid of cell organelles.
In this scenario, the scientists are planning an experiment using a light microscope to collect data. Thus, the statement which best describes how the scientists can identify nonliving samples is that, the scientists should look for samples that do not have a nucleus or cell membrane when viewed under the microscope.
