While researching a topic, a student has taken the following notes:
· The human tongue contains taste receptors for a rich, savory flavor called umami.
· Umami is triggered by the compounds in a variety of foods, including tuna and soy sauce.
· Participants in a study tasted a sample of sugar kelp, a type of brown seaweed.
· They rated its umami intensity as moderate.
· The participants tasted a sample of ma-konbu, another type of brown seaweed.
· They rated its umami intensity as high.
The student wants to emphasize a difference between the two seaweeds. Which choice most effectively uses relevant information from the notes to accomplish this goal?
