Microbiome Review

All living things contain a NUCLEUS and a CELL MEMBRANE. Non-living things DO NOT.

Which statement describes if a scientist wanted to identify a Microscopic non-living sample.

• The scientist should look for samples that do not have a regular pattern viewed under a microscope.

• The scientist should look for samples that have objects that look bigger viewed under a microscope.

• The scientist should look for samples that do not contain a nucleus or cell membrane under a microscope.

• The scientist should look for samples that have carbon atoms under a microscope.
