I'll go through my answers. Some will definitely be wrong but i wrote down everything I answered in the exam.
1. Mitosis, Meiosisdna replication, anaphase.
genetic variation: discussed crossing over at chiasma in Prophase 1, random mutations, random mating and random fusion of two gametes and independent assortment in metaphase 1 and 2 = random allele combinations
2. Overall increase from first year of data to last, fluctuates throughout, data to support this
Data reliable as its annually recorded? Irrelevant as its no reflection on pop size, illegal hunting my of occurred?
Pop size: intra and inter comp for food, space,water etc. possible disease with date, illegal hunting and predation
Wolves introduced to maintain biodiversity as elk pop. too high for carrying capacity of ecosystem
3. the one marker was easy (just the code bit)
I discussed the chain termination method and mentioned electrophoresis for the 4 marker but was very unsure.
Bronchioles- loss of elasticity of smooth muscle due to tissue damage from excessive coughing?
less force and pressure to push air out of lungs
mutation causes change in nucleotide bases so receptor active site changed, loss of function, not complementary so can't bind
other drug worked as may have receptors for it
Invalid due to small test size= only 31 kids on each drug
i put nuclear DNA for saliva but thats 100% wrong
4. geographical isolation, genetic drift
C because greater frequency of alleles changed and smaller population
Chi- 1401, reject Perhaps due to episatis or some sort of linkage (sex?)
5. Bomb calorimeter burn organisms in oxygen, calc wet-dry mass, NPP, Not all plant digested
FEBADC
Reflex, habituation,taxis,insight,imprinting
Both release specific hormones in times of stress and both go to target cellsplants-
mitosis, veg propagation of suckers, haploid in gametes diploid in plant tissue but idk
polyploidy question? larger cells, more offspring
Positive phototropism, auxin distribution, cell elongation turgid cells = bend to light
human- innate behaviour, automatic reflex to move to prevent damage to body
all i got for cell death was that they might burst,and oxygen deprivation in 2nd one
said anticoagulant type treatment may increase blood viscosity causing even higher blood pressure
cerebrum and cerebellum involved, neurones can't transit action potentials?
disadvantage as reproduction rates decrease, high nicotine means less seeds. nicotine no advantage to plant?
postsynaptic membranenicotine q can't really remember- talked about complementary and same shape, bind instead of acetylcholine, less transmission of messages, no standby return
diffuse through xylem in vascular bundle
we have enzymes to break down substance ?
