Arecent clinical study demonstrated a possible connection between coffee consumption and heart health. the researchers performed a 6-week trial with 191 individuals, all of whom were heavy coffee drinkers (average of 5 cups/day) prior to the experiment, but none of whom were smokers. they divided the 191 participants into three groups: no coffee consumption, 1-3 cups/day, and 4 or more cups/day. they measured blood levels of cholesterol and homocysteine as indicators of heart health. only the no-coffee group showed a significant drop in both indicators. previous studies had demonstrated that decreases of the magnitude observed in the no-coffee group could cut the incidence of heart disease by 10-15%.

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
