A researcher wants to study the human sense of taste over a life span. The researcher has a group of participants taste foods that are salty, bitter, sweet, sour, and umami. Which study would best allow the researcher to test the sensation of taste as people age, and what is the likely outcome? a. The researcher follows the same group of people over the course of 40 years. The researcher also measures the number of the people's taste buds throughout the 40 years. The researcher finds that as people grow older, their sense of taste diminishes and their number of taste buds decreases. b. The researcher follows the same group of people over the course of 40 years. The researcher also measures the number of the people's taste buds throughout the 40 years. The researcher finds that as people grow older, their sense of taste remains the same because as their number of taste buds decreases, each taste bud becomes more sensitive. c. The researcher tests a group of 50 ten to twenty-five year olds, 50 twenty-six to fifty year olds, and 50 fifty-one to seventy-five year olds at the same time. The researcher also measures the number of the people's taste buds for each group. The researcher finds that as people grow older, their sense of taste diminishes and their number of taste buds decreases.
