1. Daisies are flowering plants frequently found growing amongst grasses on lawns.
A student earned money by cutting the grass on the lawns of his neighbours. Each
neighbour supplied a lawn mower. These were of two types: those that had a box to collect
grass cuttings and those that did not. He noticed that there appeared to be more daisy
plants on lawns where the grass cuttings were left on the surface.
He set up a controlled investigation to test whether this observation was significant. He
took a random selection of four lawns which were cut using a grass box and four which
were cut without a grass box.
On each lawn he used a randomly placed 0.5 × 0.5 metre quadrat divided into 25 smaller
squares. He counted the number of smaller squares in which daisies were present. This
was then repeated ten times for each lawn.
The raw data from his investigation are shown below.
Lawn mower with a grass box
Number of squares in which daisies found
Lawn 1 2, 4, 0, 4, 2, 4, 4, 0, 3, 1
Lawn 2 4, 3, 0, 1, 1, 1, 5, 3, 0, 2
Lawn 3 0, 1, 1, 2, 1, 0, 0, 1, 2, 3
Lawn 4 3, 5, 12, 2, 4, 6, 2, 7, 2, 10

2. The banded snail (Cepaea nemoralis) has many varied phenotypes, ranging from a shell
having a single stripe to one having six or more stripes. An example of a banded snail is
shown in the photograph below.
Magnification ×2
The main reason for this variation in numbers of stripes may be due to selection by
predators, since the different phenotypes provide camouflage in different habitats.
The song thrush is a major predator of banded snails. The song thrush carries the snail to
a favourite place containing a large stone, called an anvil stone. Here it repeatedly hits the
snail on the anvil stone until the shell breaks open. The snail is then eaten and the shell is
left behind.
The shells left near the anvil stone form a useful way of monitoring the type of snail
selected by individual birds.
Design an investigation to test the hypothesis that banded snails with more stripes are
better camouflaged in open grassland areas than in woodland.
Your answer should give details under the following headings.
