biology unit 2 helpWatch
My assumption would be something to do with diffusion within cells.
*update- it might be something to do with the amount of food in the stomach, and muscles tighten/flatten based on amount of food?
its worth 2 marks and i was given figure 6 which is mitochondria and it has a scale bar of 0.1mm(i think the scale is for part b) at the start of the question it states 'figure 6 shows some muscle cells from the wall of the stomoach, as seen through a light microscope
Can you think on anything else stomach muscle does?
I'm guessing you'd say that the muscle cells contract and relax, digesting the food in the stomach. They need energy in the form of ATP do to this. Mitochondria synthesise ATP. (Don't know if you've been taught about ATP yet so just say mitochondria are a source of energy). Hope I helped!
