- 2Species RichnessNumber of species in an area
- 3Species EvennessHow many individuals there are of every species in an area
- 4BiodiversityVariety of...
Species
Ecosystem
Alleles
...in an area - 5PhylogenyEvolutionary relationships (ER) between organisms
Study of closeness of ER
Basis of modern classification
The closer the ER the closer the taxonomic group - 6Dichotomous KeyEach question has two options
- 7Immune ResponseResponse to an antigen that
involves production of antibodies - 8NeutralisationAntibody binds to specific antigen
Cover binding sites on pathogens
Can't enter cell - 9AgglutinationAntibodies bind together many pathogens
Clump is too large to enter host cell - 10Balanced dietContains each nutrient in right proportions
- 11Describe how you would carry out emulsion testAdd ethanol to sample
Shake
Add Water - 12SpeciationThe formation of new species
- 13Continuous VariationDifferences between individuals that cover a range of values rather that discrete categories
- 14AdaptationA variation that increase the chances of survival
- 15BinomialA system of naming
organisms that uses two
scientific (Latin) names for
species - 16ex situThe type of conservation
of which seed banks are
an example - 17Environmental Impact Assessment/ EIAA study carried out by a
local planning authority in
order to judge the effect of
a development on the
biodiversity of an area - 18Name the vector for the malarial parasiteFemale Anopheles
- 19Name the five KingdomsProkaryotae, Fungi, Plantae, Protoctista, Animalia
- 20Symptoms of emphysemaShortness of breath
Barrel chest
Pulmonary hypertension
Fatigue - 21Action of B lymphocyte in immune resposeB 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 - 22Structure of glycogenCarbohydrate (polysaccharide)
Alpha glucose units
1-4 Glycosidic bonds
1-6 Glycosydic bonds
Branched - 23Structure of collagenProtein (polypeptide)
Amino acid units
Peptide bonds
Helical
3 chains per molecule
Cross links between chains - 24Effect of NicotineIncreases heart rate
Constricts atrioles
Makes platlets sticky - 25Effect of carbon monoxideDamages lining of arteries
Reduces ability of Hb to carry oxygen - 26Role of LDLs in frormation of atheromaDamage to endothelium
LDLs collect at site of damage
LDLs deposited in arterial walls - 27Function of disulfide bridge and hinge region of antibodyHold polypeptide chains together and hold 3D shape of molecule
Allow molecule to flex - 28Why is variable region improtantDifferent antibodies have different amino acid sequences.
Different antibodies have different shapes
to fit different antigens. - 29Haemoglobin vs. Collagen
- 30Amylose vs CelluloseBoth 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
