| Frage | Antworten |
| Name the infective agent that causes TB | Mycobacterium |
| Species Richness | Number of species in an area |
| Species Evenness | How many individuals there are of every species in an area |
| Biodiversity | Variety of... Species Ecosystem Alleles ...in an area |
| Phylogeny | Evolutionary relationships (ER) between organisms Study of closeness of ER Basis of modern classification The closer the ER the closer the taxonomic group |
| Dichotomous Key | Each question has two options |
| Immune Response | Response to an antigen that involves production of antibodies |
| Neutralisation | Antibody binds to specific antigen Cover binding sites on pathogens Can't enter cell |
| Agglutination | Antibodies bind together many pathogens Clump is too large to enter host cell |
| Balanced diet | Contains each nutrient in right proportions |
| Describe how you would carry out emulsion test | Add ethanol to sample Shake Add Water |
| Speciation | The formation of new species |
| Continuous Variation | Differences between individuals that cover a range of values rather that discrete categories |
| Adaptation | A variation that increase the chances of survival |
| Binomial | A system of naming organisms that uses two scientific (Latin) names for species |
| ex situ | The type of conservation of which seed banks are an example |
| Environmental Impact Assessment/ EIA | A study carried out by a local planning authority in order to judge the effect of a development on the biodiversity of an area |
| Name the vector for the malarial parasite | Female Anopheles |
| Name the five Kingdoms | Prokaryotae, Fungi, Plantae, Protoctista, Animalia |
| Symptoms of emphysema | Shortness of breath Barrel chest Pulmonary hypertension Fatigue |
| Action of B lymphocyte in immune respose | B lymphocyte has antigen receptors Clonal selection - selection of B lymphocytes by APCs Clonal expansion - selected cells divide B cells differentiate to form plasma cells or memory cells |
| Structure of glycogen | Carbohydrate (polysaccharide) Alpha glucose units 1-4 Glycosidic bonds 1-6 Glycosydic bonds Branched |
| Structure of collagen | Protein (polypeptide) Amino acid units Peptide bonds Helical 3 chains per molecule Cross links between chains |
| Effect of Nicotine | Increases heart rate Constricts atrioles Makes platlets sticky |
| Effect of carbon monoxide | Damages lining of arteries Reduces ability of Hb to carry oxygen |
| Role of LDLs in frormation of atheroma | Damage to endothelium LDLs collect at site of damage LDLs deposited in arterial walls |
| Function of disulfide bridge and hinge region of antibody | Hold polypeptide chains together and hold 3D shape of molecule Allow molecule to flex |
| Why is variable region improtant | Different antibodies have different amino acid sequences. Different antibodies have different shapes to fit different antigens. |
| Haemoglobin vs. Collagen | |
| Amylose vs Cellulose | Both Glucose bonded together with Glycosidic Bonds. Both are insoluble. Cellulose is composed of β Glucose and forms long straight chains, in which every other Glucose monomer flipped over, whereas Amylose is composed of α Glucose, forms a coiled chain |
