You note the organism appears to be “eating” the smaller microorganism. Chemical analysis of test tube 2 indicates the presence of a chemical that is toxic to fish and humans. In test tube 3, you detect the presence of substantial amounts of silica. Microscopic analysis of organisms in tube 4 reveals the presence of an apicoplast in the organism Microscopic analysis of the contents in tube 5 reveals the presence of one large macronucleus and several small micronuclei in each organism Match the description with the correct protistarrow_forward
