Which of the following statements correctly describes the difference between saturated and unsaturated fats?

• Saturated fats tend to be solid at room temperature; unsaturated fats are liquid at room temperature

• Saturated fats are cannot pack together closely because of their bent structure; unsaturated fats can pack together because they are flat

• Saturated fats come from plants and fish; unsaturated fats are from animals (except fish)

• Saturated fats are considered “healthy” fats; unsaturated fats may contribute to cardiovascular disease

What do the error bars in the graph say about data?

• The data for Group 1 has a lower mean value.

• The data for Group 2 has a higher degree of variability.

• The data for Group 1 has a higher degree of accuracy.

• The data for Group 1 and 2 has the same degree of coefficient of variation.
