The diagram shows how the effect of gro ; xwl.u/ 2icvsxm/4ddwing bacteria with different antibiotics can be investigated. A study was conducted to test the degree of antibiotic resistance that bacteria from a hospital door handle had developed. Measurements of the zone of inhibition .cdxvux 2w4li ;m/s/dwere taken every 3 days, for 15 days.



1.State which antibiotic is the least effective at preventing bacterial growth.

2.State two variables that must be controlled in this experiment, other than those already given.

3.1.Identify the anomalous result from the study.

3.2.Suggest how the anomalous result may have arisen.

4.Explain how natural selection can lead to antibiotic resistance in bacteria.

5.The researchers suggested that vancomycin could be used more extensively to treat bacterial infections. Discuss to what extent you agree with this.

Sickle cell anaemia is a trait that ix8a .9hg zyz4ys inherited in a codominant manner. The graph shows the proportions of people who are homozygous affectgy.zhz x8y9 4aed (Hb$^S$Hb$^S$ ), homozygous unaffected (Hb$^A$Hb$^A$ ) and heterozygous (Hb$^A$ Hb$^S$ ) for the trait over 50 years in Nigeria, West Africa. Malaria, which is a parasitic disease that infects red blood cells, is prevalent in Nigeria.

1.Using the graph, explain whether the sickle cell trait is likely to be in Hardy Weinberg equilibrium.

2.1Describe the trends observed in the graph.

2.2.Suggest a reason for the trend in heterozygotes found in this malaria infected region of Africa.

3.The frequency of the recessive allele in the population was found to be 0.62, calculate the frequency of the dominant allele in the population.

4.1.Assuming that this population is in Hardy Weinberg equilibrium, predict what would happen to the frequency of recessive alleles in the population over 50 more years.

4.2.Outline a reason for your answer.

5.Explain why, under ‘real world’ conditions, it is difficult for organisms to be in Hardy Weinberg equilibrium.
