Explain how a root hair cell is specialised for its function.

Figure 6 shows a microscope.

It is easier to view the cells using the low power objective lens first.

Give one reason why.

To focus the image the objective lens should be moved away from the stage.

Give one reason why the objective lens should not be moved towards the stage.

The image of the prepared slide in Figure 6 is viewed with the ×10 objective lens.

The total magnification is ×50

What was the power of the eyepiece lens used?

Root hair cells do not contain chloroplasts.

Suggest one reason why.

Figure 1 shows one type of white blood cell.

What is structure A ?

Tick one box.

White blood cells help to defend the body against pathogens.

How do the white blood cells do this?

Tick three boxes.

Measles is a serious disease. A person can die from measles.

Figure 2 shows the number of cases of measles in England and Wales between 2012 and 2015

Use Figure 2 to calculate the decrease in the number of cases of measles between 2012 and 2015

Suggest one reason for the decrease in the number of cases of measles between 2012 and 2015

Antibiotics cannot be used to treat measles.

Suggest why.

Gonorrhoea is a disease caused by a bacterium.

Gonorrhoea can be treated with antibiotics.

Give one other way to control the spread of gonorrhoea.

A scientist investigated how effective different antibiotics were at killing gonorrhoea bacteria.

This is the method used.

1. Grow gonorrhoea bacteria on agar in a Petri dish.

2. Place one paper disc soaked in water onto the agar.

3. Place four other paper discs, each soaked in a different antibiotic, A, B, C, and D onto the agar.

4. Use the same sized paper discs and the same concentration of each antibiotic.

5. Incubate the Petri dish for 3 days.

Figure 3 shows the scientist’s results.

A clear area around the disc means the antibiotic has killed the bacteria.

Give one control variable the scientist used.

Suggest why one disc was soaked in water.
