Question

the class notes that all four samples are made up of a single cell. what does this allow the class to infer about all the samples? select two. they are samples of living objects. they are samples of nonliving objects. they are large enough to be seen by the eye. they are multicellular organisms. they are unicellular organisms.

Explanation:

1. For "They are samples of living objects": All single - celled organisms are living because cells are the basic unit of life, and these samples are made of single cells, so they are living objects.
2. For "They are unicellular organisms": The definition of a unicellular organism is an organism that consists of a single cell. Since all four samples are made up of a single cell, they are unicellular organisms.

• "They are samples of nonliving objects" is wrong because cells are the building blocks of living things, so single - celled entities are living.
• "They are large enough to be seen by the eye" is not necessarily true. Most single - celled organisms are microscopic and cannot be seen with the naked eye.
• "They are multicellular organisms" is wrong because multicellular organisms are made up of many cells, while these samples are single - celled.

Answer:

• They are samples of living objects.
• They are unicellular organisms.
