Write a short paragraph to explain why the sugar could get through the membrane, but the starch could not?

Selective permeability. When many glucose molecules combine they form one large molecule called starch. Due to starch being a larch molecules they have difficulty passing through the membrane. Glucose molecules are smaller in size therefore they can pass easily through  the membrane.

Explanation:

Selective permeability the the process whereby the cell membrane allows for selective molecules to pass through its membrane, in order to obtain internal equilibrium.

the glands which are associated with each description is given below:

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
