First question is - Why do we have limestone? Formed from this type of sediment are biological sedimentary rocks. Their biological organ is often revealed in the rock fossils. Some limestones can form by direct precipitation of calcium carbonate from marine or fresh water. (The second question is) - What do iron bands mean? The rocks are "banded" because the iron minerals deposited in alternating bands with silica and sometimes shale. The banding might have resulted from seasonal changes in organism activity steel mill.

The missing part of the question is as follows:
Phrase indicates a limit to the scientific accuracy of the experiment?
Answer:
The correct answer is - a sample size of 300 people.
Explanation:
In the given research Marcus developed a drug that is already 200,000 people taking the drug, and the scientist takes sample size of only 300 people for the experiment.
The sample is very small as compared to the total population who participated in the research. A sample size of 300 people is very small compared to 200,000 people. Such a small sample size will not give the proper idea and any effective result, there would be chances to miss some aspect or effect of the drug to be missed, so, this can be the limiting factor to the experiment.
