Answer: representative data
When designing an experiment a benefit of larger sample sizes would be more representative data. This larger sample size would lead to perfect result.
If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.
The actually speed of sound in water is 1,498, which is closest to 1,500 meters per second.
