C. Difficile is a bacterial species that causes disease in humans. Scientists suggested that people eating more trehalose in their diet led to an increase in antibiotic-resistant C. difficile infections.

Use figure 2 to evaluate whether more trehalose in the diet could be a factor in the increased number of antibiotic-resistant C. difficile infections [3 marks] {P1}

Some scientists have suggested that people should be vaccinated to prevent infection by chlamydia. Evaluate this suggestion [3 marks] {P1}

The scientists studied five individuals from each species. Within the five individuals of species T they found a percentage similarity of 66%.

Use Table 3 to evaluate how this information affects the validity of the phylogenetic tree. [2 marks]

A journalist saw Figure 10 and suggested that future increases in atmospheric carbon dioxide concentration could result in less transpiration.

Evaluate his suggestion [4 marks]

Explain the shape of the curves at 50^oC and 60^oC [4]
