    And also I've noticed that there is a REALLY high possibility of reproduction and whatnot would be on the paper because of the number of times it appears on the previous past papers, something to do with respiration (i think plants and humans - I'm making sure to know everything about anaerobic rest. + aerobic). Cloning i think will be on there due to the fact it never came up in last year's paper and Jan 2016's, i think that there's a high possibility of coordination and response and transpiration since that didn't come up as well. Making sure to look at specification:

    dont get what we need to know about fish farming
    Basically all that money stuff because consumerism is for the win!

    So we farm them for food (which I don't agree with cause 'fish are friends not food' (sorry my inner 5 year old))
    the fish are kept in special tanks, water is monitored for the temperature, pH and oxygen level, and the water can also be filtered to avoid pollution. the tanks also stop them from using lots of energy
    Fish are separated by age, size, species, etc.
    this stops them from eating the little fish Intraspecific Predation
    they are kept caged off which prevents Interspecific Predation (predators such as birds killing them)
    Kept on a diet of food pellets which are high in energy, because the better the quality the bigger and quicker the fish will grow (this gets the farmers more money)

    There, anyone else feel free to add
    You just need to know how to increase the money you get, and why you might not get money from it
    Who's excited for tomorrow?

    If the ph probe in a fermenter stops working and the fermenter becomes acidic, how does this affect the production of human insulin?

    what do we need to know about the menstrual cycle
    We need to know the stages, there are four:
    Stage 1- bleeding starts, the uterus breaks down for about four days
    Stage 2- The uterus lining is built up again from day 4 to 14, a think spongy layer of blood vessels ready to receive an ovum
    Stage 3- an ovum is developed and released on day 14
    Stage 4- the all is maintained for 14 days, if the ovum has no been fertilised the lining breaks down and the whole process starts again.
    We also need to know about the role of progesterone and oestrogen
    progesterone- maintains the lining of the uterus
    oestrogen- caused the lining to thicken and stimulates LH to release an ovum
    Hope that helps xxx
