There are so many possibilities it's unlikely we could guess, but examples could be:

B4: types of organic farming and how they are better
B5: describing the cardiac cycle
B6: advantages and disadvantages of biofuels

But once again, it's difficult to guess unless you know what they've been in past papers.

B4 - something like transpiration in plants and how they are adapted to speed/slow it

B5 - could be so many things! possibly kidneys or menstrual cycle

B6- hmm maybe biogas production and then pros and cons of biofuels

these are just wild guesses

this is true put I asked about decay not plant growth :P by breaking down detritus the saprophytes increase the surface area of the plant material making it easier for micro-organisms to feed on the particles, speeding up decay :smile:

First a sample of DNA is extracted from human body tissue
Then it is fragmented using restriction enzymes
Then is is separated using electrophoresis
Then the DNA finger print is visualised using a radioactive probe.

what are the problems associated with longer life expectancy?

there needs to be more old people's home as a result
it put mroe strain on government and economy as pensions need to be paid for longer
NHS need to spend mroe money on health care for old people if they live longer.
I thinkthat's it...

What are the similarities and differneces between a kidney tubule and a dialysis machine and how it the dialysis machien adapted to work efficientlly?
