This indicates a possible problem with the ribosome of the cell. Ribosomes in cells are responsible for translation the genetic codes in mRNA to appropriate proteins with the help of tRNA. mRNA, rRNA, tRNA and ribosome work together during protein synthesis to produce chains of amino acids that are linked together by polypeptide bonds.
What this student is doing is collecting data. So, he wants to check how many life forms there are in the waters nearby. In order to do so, he has to take a sample, and look at it through a microscope so as to determine the number. So, he collected a sample which is his data.
