b- 2 steps in the scientific method that lead to a theory
c- 2 limitations of the scientific method
d- explain 'double blind'
e- give the term used to distinguish right from wrong (immoral) conduct3)nerve question-aint done this chap so only read it… they ask what grey and white matter is made of, label a nerve cell, something about where impulses..
4a- light is absorbed by pigment molecules of a chloroplast to which specific type of chlorophyll molecule is it passed?
b- where do these take place
i- light dependant stage
ii- light independant stage
c- give features both pathways have in common
d- which pathway...
i-elevation of electrons to their highest level?
ii- acceptance of electrons from the lysis of water
e- role of NADPH in the dark stage5a- which of the 5 kingdoms is bacteria from?
b- label bacteria (given round shape) show 3 things in bacteria not in other micro organisms
c-name type of bacteria (drawn above in b)
d- name a disease caused by this bacteria
e- draw bacterial growth curve with 5 phases6a- difference between diffusion and osmosis
b- example of osmosis in food preservation
c- what gas diffuses out of leaf as result of cellular respiration
d- give a material used as semi-permiable membrane to demonstrate osmosis
e- 1 difference between active transport and other forms across biological membraneslong questions:
11ai- explain the CNS (central nervous system) in humans
ii- 2tissues protecting it
bi-functional unit of kidney
ii-draw it + its blood supply
iii-how is urine formed in kidney?
ci- what hormone controls urine + give gland its secreted from
ii- which area of kidney does it target?
iii- what happens when water content in the blood is low
iv- 2 other organs of excretion + a waste product of each (not water)12ai- whats parasitism +symbiosis?
ii- difference between ectoparasite + endoparasite?
b- 30 grasshoppers caught on 1st day + marked. 2nd day 24 caught. 6 of these have the mark.
i- suggest a technique to capture small animals like grasshopper
ii- estimate size of grasshopper population +show your workings
iii- name a method of estimating population size
iv difference between qualititive and quantitative surveys
v- using a graph (given) give 2 reasons why species A is prey and species B is predator
vi- 1 abiotic factor which could have influenced this
ci-draw + label a pyramid of numbers (with 4 trophic levels)
ii- (in a named habitat) 1 organism for each trophic level
iii- 2reasons why there’s a large difference between the no. of primary consumers andsecondary consumers.
iv- why are ecological pyramids used? + 1 limitation of them14 (do 2 of a, b, and c) i did b and c...
bi- (given diagram of a stage of mitosis) which stage is it?
ii- what happens in this stage? + how many chromosomes in each new cell
iii- why is DNA replication important before cell divides by mitosis? describe the process of DNA replication
iv- in which phase does DNA replication take place?
v- function of mitosis in a single celled + multicelled organism
ci- write out thw full words for these abreviations: ATP, NAD, NADP+
ii word structure of ATP + a diagram to show energy location
iii- ATP energy release the molecule is converted to what?
iv- (fill in a table put either a tick or an x under each heading after each question) headings:
glycolysis, krebs cycle, light dependent reactions of photosynthesis.
Qs: NAD is used
NADP is used
ATP is produced
ATP is requiredQ15 a) was human reproduction label both male and female reproduction systems.
Say which part on diagram is where; testosterone is produced,foetus develops and fertilisation occurs.
Define secondary sexual characteristics. On either female or male example, give 2secondary sexual characteristics and the hormone responsible for their development
embryo develops …name the 3 germs cells there and the organs each 3will develop into
b) was blood especially white blood cells-distinguish between monocytes n lymphocytes
something about T-cell n B-cells
then heart. The valves and vessels that bring blood in and out
c was transport in flowering plants…draw phloem or xylem. No cohesion tension model.what xylem and phloem transport apart from water.think Q10 was about respiration
Experiments- We were able to do one! We hadn’t the other two done yet. Heat affect in enzyme activity-easy questions on graph. What does an enzyme work on? Know what you kept constant. Bit of the process. Nothing tricky!
IAA were up..didn’t look at it cause couldn’t do it. Leaf yeast experiment were up to…again..didn’t see it cause couldn’t do it!That’s all I did and can remember! Good look
