Which statement is a possible hypothesis for this experiment that could be 1 point supported by the results of this experiment? *
If the average number of chloroplasts in euglena decreases, will less nitrate be
needed in each tank?
If the nitrate concentration is increased, then the euglena will have a lower average
number of chloroplasts.
If the number of euglena in a tank increases, will more nitrates be produced?
If the nitrate concentration is decreased, then more light will reduce the average
number of chloroplasts in euglena.
