Biology mocks

Anyone know what topics to revise which are in the AQA biology mocks

Yes, revise the composition of bones, there is a 4 marker on that for some reason. Something about calcium.
difference monocotyledons eudicotyledons number of cotyledons in the seed 1 2 pattern of leaf veins parallel/AW ; branched/network / AW ; number of petals present 3 / multiples of (up to 60) ; 4 or 5 / multiples of (up to 60) ; [4] [Total: 4] 2 (a) (i) bacteria (in mouth) ; (bacteria) change or respire sugar/ named sugar (in food) ; (sugar) to acid/ lactic acid ; acid dissolves /attacks, enamel/ teeth/ dentine/top layer/AW ; anaerobic respiration ;

brushing: dislodges, plaque/ bacteria/ food (particles)/ sugars (from mouth) ; rinsing: removes, plaque/bacteria/ food (particles)/ sugars (from mouth) ; not eating sweet foods between meals: bacteria have, less sugar/ food (to respire/ use) bacteria respire less / less acid produced ; [3] A antiseptic mouth-wash kills / inhibits bacteria 2 (b) (i) incisors: chop/ cut / bite /AW ; canines: pierce/ tear/grip/AW ; premolars and molars: grind/ crush/ chew/AW ; [3] R chew A canines chop/ cut / bite food A increases surface area of the food/breaks up large chunks /AW 2 (b) (ii) moves food (between teeth)/AW ; mixes food with saliva/ amylase ;

helps form a bolus ;

food small enough (to be swallowed) ora ; increases surface area ; for more rapid enzyme action/ digestion ; food mixed with, enzyme/ amylase ; food mixed with saliva/ mucus (to make swallowing easier) ; prepares stomach for receiving food / AW ; max [2] [Total: 13] A makes food softer 3 (a) bronchiole ; larynx ; trachea ; [3] one mark for each labelled line in the correct position. 3 (b) large surface area (per volume) ; thin/ small diffusion distance ; moist/wet/liquid film ; (alveolar) wall permeable ; well ventilated/ diffusion gradient maintained ; well supplied with capillaries / diffusion gradient maintained ; max [3] A answers in context applying to animals other than mammals.

3 (c) (i) 82.95(dm3 / min) ;

breaths more rapid /AW ; breaths deeper / heavier /AW ; [2] A diaphragm/ external intercostal muscles, contract more rapidly / frequently 3 (c) (iii) more oxygen needed ; more (cell) respiration carried out ; more energy is required ;

more muscle contraction

Sorry may be pushing this but how about chemistry and Physics. And could you simply state the topics or subtopics in biology test in a list in relation to questions for this and chemistry and physics (that would be great thanx)
