Good quiz but it's bacteria that are used to make cheese and yoghurt.
and Kirtey, veins don't dilate because its arteries that are carrying the oxygen to the body. Veins are only carrying de oxygenated blood back to the heart, so they dont need to adapt when exercise is under way... hope that makes sense!
Appologies for the question mistake, and for some reason the answers that seem to not be finished, are finished in the page where I entered the answer to make the quiz, but not when it gets published. So, sorry again, but thanks for the poisitive feedback :)
Yeah, good quiz I haven't covered all the unit yet soo was glad I got what I got but shows what I need to go back over!! Thanks again, keep up the good work everyone!!
Btw I thought the veins diluted too but thanks #Fiona for giving an answer which helped me understand this...
