Some people believe in global warming because of the over population and constant factory's creating pollution.
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.
Answer:
50%
Explanation:
Since A is only repeated twice, it could be 50%.

Energy must flow through autotrophs because they take the energy from the sun, then herbivores feed off the autotrophs converting energy from the plant into energy that they can use. Carnivores then feed off the herbivores, and finally carnivores feed off of each other, and the process starts over again. Heterotrophs only generate a small fraction of their energy through photosynthesis, making autotrophs very important.
