Most likely the students are using a crude measurement of time, like a stopwatch. They would get the best results with a scientific apparatus that uses a computer and optical sensors. Even recording their dropped objects with a video camera and analyzing the video would give more consistent results. Results will also vary greatly if different people are taking the time measures instead of one person making all measurements.
The answer is <span>Special RNA polymerase, peptidoglycan in cell walls, ester-linked fatty acids.
Bacterial cell wall consists of peptidoglycans, not of cellulose or chitin. They also have ester-linked fatty acids, like eukaryotes. Ether-linked fatty acids are characteristics of Archaea. Also, bacteria have special RNA polymerase, unlike Eukaryotes that have three different type of RNA polymerase.</span>
D) The island will suffer a loss of native plant and animal species. Due to loss of plants the animals living in a particular area might not be able to find food to survive causing them to die eventually because of starvation
Hydrogen would be the answer to this.
