In this learning activity you'll observe information and formulate an evaluation that includes diagnosis and microorganism identification.
Learners match the names of parasitic organisms to the diseases they cause and the modes of transmission.
Learners listen to the pronunciation of the binomial names for microorganisms and then type the words. They may choose the number of names that they wish to spell (up to 112). Immediate feedback is given, and a final score is provided at the end of the activity.
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
Learners test their knowledge of fungal diseases by completing six exercises.
Learners listen to the pronunciation of bacteria names and then type the words. They may choose the number of names that they wish to spell (up to 70). Immediate feedback is given, and a final score is provided at the end of the activity.
