Answer:
A
Explanation:
There are different mechanisms for transport of molecules across the cell membrane. One kind of this transport is facilitated diffusion, this is a form of passive transport, not requiring any ATP (the opposite would be active transport, where it does require ATP.
Simple diffusion does require special transport proteins, and neither does osmosis. Filtration is a technique used for sterilisation of water, where any impurities can be drawn out of the liquid
Long strands of double-helical DNA fit into the nucleus of a single cheek cell, the double helix is packaged and wrapped around proteins, folded back onto itself and coiled into a compact chromosome. 4.
For this problem, the most probable and the most likely answer for this would be the second option which is cells.
When viewing, not just corks, but other things under a microscope, may it be a home-made one or of something in value or a technologically advanced microscope, small compartments would always be visible under these lenses and they are cells. Some might look like boxes but they are cells. These cells might come in many sizes, but they will always be cells. Cells are everywhere.
