Nnenna, who was already academically ahead by at least a year and a half, spoke clearly, with confident ease.
"So, if you want to identify parasites quickly during practicals or diagrams," Nnenna began, "you need to remember their signature patterns."
"Like what?" Ava asked, scribbling in her jotter.
"Okay," Nnenna counted off on her fingers, "tapeworms are flat and ribbon like. They almost always have segments, like tiny boxes strung together. If you see something that looks like a flattened centipede in a diagram? That is a tapeworm."
Ava nodded quickly.
"And flukes," Nnenna continued, "they are leaf shaped. Most of them are hermaphroditic and have suckers near the mouth area. Their shape is key, once you spot the oval or leaf form, flukes should come to mind."
"Ugh. Gross, but okay," Ava said, making a face but jotting it down anyway.
"Oh! And nematodes, roundworms, are unsegmented and smooth, usually with tapered ends. They look like thin spaghetti noodles, if that helps."
