  Eating a healthy, balanced diet is important in order to cnxn, 8rcyx;* maintain overall health and a strong immcnx *x8y;c,r nune system. A healthy diet means eating a wide variety of food whilst limiting the consumption of foods which are considered to be less healthy, such as those high in saturated fats.

In an investigation into the effects of diet on low-density lipoprotein levels (LDL) in the blood, scientists provided two groups of mice with varied diets. Each group was given 5g of food per day, containing a mixture of a standard food mix and either avocado or cheese. The ratios of the food were changed each day and blood LDL levels were recorded. The diets and results are shown in the tables and graph.



1.1.Describe the impact on blood LDL levels when feeding mice diets supplemented with avocado or cheese.

1.2.Explain the differences between results from both groups.

1.3.Suggest a reason for the trend shown in LDL levels in group one.

2.State which group is most at risk of heart disease and stroke. Give a reason for your answer.

3.1.Suggest one advantage of using mice in this experiment instead of humans.

3.2.State one variable, not mentioned in the question, which would need to be controlled in this experiment in order to achieve valid results.

4.For mice fed with cheese, calculate how many times greater the LDL levels were on day 5 compared to day 2.
