    for the comparing the genders one, i added up the total for the males from the graph and minused that from the total amount of people in 2011 using the previous table, i got females were more likely, and i got like 92.5% females or something. was the general answer females were more likely?

    I think you over complicated it corey7695, If 60% of people with kidney problems were male then 40% had to be female?

    And that trend of higher than 50% male was common throughout the table

    Adaptation of granum - it is near the stroma so short transportation distance of light-dep products to light-ind reactions?

    did the labelling mitochondria question require the letters or the names of the parts???
    Surely the letters, they wouldn't have given us them otherwise.

    For why we shiver I put, increased temperature reduces activity of acetylcholinesterase, so ACh is not hydrolysed and remains in receptor, so sodium channels remain open causing the continued stimulation of action potentials in post-synaptic membrane leading to muscles. Could be wrong, anyone else put something like that?

    What did you put for why insulin is still secreted, guys? I put because calcium ions still present in the cell and takes time to remove by active transport, so still causes exocytosis.

    for the dextrose question, i mentioned how it would have a low w.p which would cause excess fluids which have accumulated in the tissues(due to kidneys not filtering it out) to diffuse out by osmosis, this sound reasonable?

    I put because it takes a while for calcium ions to be removed from the cell via active transport, so their presence will still cause exocytosis even when glucose doesn't enter the cell
