A student performed an investigation on green single-celled organisms called Euglena. Two samples of Euglena were
placed in two different containers of water taken from the same
source. One sample was kept in a dark area. The other sample
was kept in a lighted area. The student recorded the
observations in the table shown. Which of the following
