Rank the molecules below from smallest to
largest:
1. Starch
2. Glucose
3. Water
4. Pores in dialysis tubing
5. IKI
Answer:
smallest to biggest is 3,2,5,4,1
Explanation:
this is the order for smallest to biggest
Ranked the molecules below from smallest to
larges
Water-Glucose- Starch- pores in Dialysis tubing- IKI.
Living cells need to obtain nutrients from their environment and get rid of waste materials from their surroundings. This exchange of materials between the cell and its surroundings is crucial to its existence. Cells have membranes composed of a phospholipid bilayer embedded with proteins.This cell membrane can distinguish between different substances, slowing or hindering the movement of other substances and allowing others to pass through readily. This property of the cell is known as selective permeability (Ramlingam, 2008).Water is the smallest size among the given substances i.e. about 0.27 nanometers followed by glucose whose size is 1.5 nanometers. The size of starch ranges from 2 to 10 nanometers whereas the size of pores present in the dialysis tube ranges from 0.1 to 10 nanometers.The last IKI has the largest size of 138.5 km² which is an Island located in Japan so we can conclude that the above rank is based on the smallest molecule to the largest one.
