Question

One of the primary advantages of cell culture is the ability to isolate a single type of cell from a multicellular organism. How has this advance changed the study of biology?

Single-type cultures are easier and cheaper to maintain than cultures made of mixed cell types.
Scientists can completely avoid using animal or human test subjects during their experiments.
Cultures with single cell types behave in culture exactly as they would behave in a tissue or organ.
Scientists know that any response during an experiment is associated only with that cell type.

Answer 1

Answer: The answer is D.

Step-by-step explanation:

Answer 2

Scientists know that any response during an experiment is associated only with that cell type.

Step-by-step explanation:

A cell culture is a group of cells that develops from a single original cell. Biologists can use cell cultures to test cell responses under controlled environmental conditions in order to study interactions between cells, and different processes occurs in it. Cell culture is one of the major tools used in the study of physiology and effect of toxic substances on the cells.
