Skeleton made of cartilage
The correct answer is B. Prokaryotes do not have a nucleus.
Explanation:
In biology, the Prokaryotes along with the Eukorytopes are types of cells. In the case of the Prokaryotes these cells are found in bacteria and similar organisms different to Eukaryotes, Prokatyoes do not have a nucleus, lysosomes or Golgi complex. But they have cell walls which are only found in certain Eukorayotes cells and as most cells they Prokaryotes also have cytoplasm. This implies in the case presented the student should not have selected "has genetic material found within a nucleus" as a feature that identifies a cell as prokaryote as these do not have a nucleus and therefore the reason Mrs. Hines should mark the student's answer incorrect is Prokaryotes do not have a nucleus.
The right answer is; This is important for laboratory safety.
Before using any chemical in the lab, one should first read the Material Safety Data Sheet (MSDS) because it is important for laboratory safety.
A Material Safety Data Sheet (MSDS) is a technical document that contains detailed information about the protective measures to take, and the possible hazards of a chemical. The Material Safety Data Sheet (MSDS) is available for all the chemicals used in the laboratory and it may be written, printed or electronic.
