S/N/141. Diversity in support structures and their functions in unicellular protoctists

The paper looks at archezoa amoebas, the simplest amoeboid phagocytic protoctists, examining various forms and functions of cell skeletons, which evolved through the secretions of the Golgi apparatus.

S/N/140. Adaptive radiation in Phylum Mollusca

The paper examines Phylum Mollusca describing the features and behaviour patterns of gastropods and cephalpods.

S/N/139. Threat Display of the Siamese Fighting Fish (Betta splendens)

The paper examines a type of labyrinthine fish, Betta splendens, describing their habitat and territorial behaviours. Research into the fish's threat response is conducted to identify the difference between the behaviours of the winning and losing fish.

C/N/136. Role of glycemic index in women with PolyCystic Ovarian Syndrome

The paper examines the functions of the glycemic index (GI) in women with PolyCystic Ovarian Syndrome (PCOS) seeking to identify whether a lower GI helps to correct the irregularity of common 'periods' and alleviate the symptoms of acne and excess hair (hirsutism) as compared to a higher GI. The co-relation between the GI and the body mass index (BMI) is shown; the ethnic background of PCOS is discussed.

C/N/130. The Role of Antioxidants in Cancer Control - A focus on Vitamin E in Cancer Control

The studies evaluating the role of tocopherols (vitamin E) have varied considerably in results. The variations in effects may have been due to confounding factors from the selection of the study population, variance for specific forms of cancer, ethnic and specific characteristics of the study population (healthy, at risk or affected), the form and quantity in which the supplements were administered, and different proportions in which the various tocopherols or antioxidants are supplemented. This paper will attempt to evaluate the role of antioxidants in the prevention and treatment of cancer, with a focus on vitamin E.

S/N/109. The structure and function of membranes

The paper examines the structure of the cell membrane describing its lipid bilayer, the membrane specific properties of proteins, diffusion and transport of ions across the membrane, etc.

S/N/108. 'Hydrogen Bonding and the hydrophobic effect are the key determinants of macromolecular structure'. Discuss this statement with reference to the structures of proteins and nucleic acids

The paper examines the factors determining macromolecules' structure focusing on the role of hydrogen bonds and the hydrophobic effect, describing the features of Nucleotides, proteins, etc.

S/N/107. Explain how progression of the cell cycle is controlled

The paper examines the phases of the cell cycle analysing the functions of the proteins responsible for the checkpoints in the control system. The factors behind the cell growth are outlined.

S/N/106. Angiosperms dominate as terrestrial plants: what major evolutionary innovations do you think are responsible for their success?

The paper examines the reasons for Angiosperms' domination in terrestrial plant life reviewing characteristics of angiosperms and their evolution in flowers. Plants' cycle life is analysed highlighting the mechanism of fruits and seeds' dispersal.

S/N/104. Describe the mechanisms by which bacteria can acquire 'foreign' genetic material. What are the consequences of the transfer for bacteria and bacterial evolution/phylogeny?

The paper looks at the horizontal (asexual) gene transfer in bacteria examining the mechanisms of conjugation, transformation and generalised / specialised transduction. Characteristics of bacteria potentially linked to horizontally inherited DNA are outlined.

S/N/143. Techniques Available for Analysing a Cytoskeletal Protein

The paper examines Cytoskeleton proteins describing the ways of locating and visualising them within the cell and the methods of purifying, identifying and quantifying them.

S/N/142. Effect of the concentration of catalase, extracted from potato homogenate, on the rate of Hydrogen Peroxide Decomposition

The paper examines the rate of Hydrogen Peroxide (H2O2) decomposition using catalase extracted from homogenised Osprey Solanum tuberosum. Conclusions are made about the chance of collision between enzyme and substate with a higher concentration of catalase.

S/N/101. Detection & identification of tissue surface carbohydrates by Fluorescin Isothiocyanate (FITC)-Conjugated Lectins

The paper examines the appearance of carbohydrates on the surface of salivary glands from the larvae of the blowfly (Calliphora erythrocephala) using FITC-labelled lectins to ascertain, identify and quantify carbohydrates' presence.

S/N/105. What is meant by the unity of biochemistry? Compare and contrast the processes of respiration and photosynthesis in plants and animals. Do 'exotic' systems such as chemoautotrophy and anaerobic photosynthesis represent fundamentally different processes?

The paper looks at the presence of recurring patterns in biochemistry examining the mechanisms of respiration and photosynthesis and analysing the differences and similarities between them.
