Answer:

B, D.

Explanation:

Based on the graph, we can determine the relationship between daily caffeine consumption and resting heart rate for some adults.

1. Positive correlation: The graph shows an upward trend, indicating that as daily caffeine consumption increases, the resting heart rate also increases. This suggests that there is a positive relationship between the two variables. For example, if an individual consumes more caffeine in a day, their resting heart rate tends to be higher.

2. Increasing heart rate: Since the graph displays an upward trend, it means that as daily caffeine consumption increases, the resting heart rate also increases. This indicates that there is an increasing pattern in heart rate as caffeine intake increases. In other words, the more caffeine consumed, the higher the heart rate tends to be.

It's important to note that the graph does not show a negative correlation (where one variable increases while the other decreases) or a constant correlation (where there is no clear pattern or relationship). Additionally, the graph does not demonstrate a decreasing heart rate as daily caffeine consumption increases.

In summary, the two phrases that accurately describe the relationship between heart rate and daily intake of caffeine based on the graph are "positive correlation" and "increasing heart rate."
