Which experiments led to changes to the original cell theory? a. experiments that showed that blood cells transport gases, waste, and nutrients throughout the body. b. experiments that showed that all cells are similar in how they metabolize and in their composition. c. experiments that transplanted synthetic chromosomes into bacterial cells to create a new species. d. experiments that established the existence of single-celled organisms and microbes.

B. Experiments that showed that all cells are similar in how they metabolize and in their composition

Explanation:

The original cell theory explained that life forms are made up of one or more cells, where the cell is the smallest unit of life and is formed from already existing cells.

The modern cell theory added that cells contain genetic material stored in the form of DNA that passes from one cell to another cell during division process.

From the original cell theory, you can observe the characteristics we can observe are that;

In the modern cell theory, we can observe characteristics such as;

You can conclude that with the development of the micro-scope and later the electronic microscope, scientists were able to view and study cells which showed that many types of cells are alike in the composition and metabolic processes.For example,cellular respiration in all cells enable the the breaking down of sugars to release energy.Similar compositions is observed in the cell membrane of all cells.

i do believe the correct answer would be the third one. location c, because earth is tilted away from the sun at this time

hope this
