One possible reason behind the inability of a certain substances to pass across a cell membrane is molecule size.
What else can I help you with?
What begins to stretch across the cell during mitosis?
the cellmembrane?
State one possible reason a certain substance can not pass across a cell membrane?
The cell membrane is selectively permeable. Some substances like molecules are too big to pass through the membrane. The membrane allows passive transport of moleculesÊ by filtration, diffusion, or osmosis.
What determines the direction of net movement across a cellmembrane?
The direction of net movement across a cell membrane is determined by the concentration gradient of a substance, with molecules moving from an area of high concentration to an area of low concentration. Additionally, the permeability of the membrane to the specific molecules also influences their movement. External factors such as temperature and pressure can also impact the direction of movement across the membrane.
Can you see across Lake Ontario from your location?
Yes, it is possible to see across Lake Ontario from certain locations depending on visibility and distance.
The movement of a substance across a concentration difference is called?
diffusion
How is nix?

The difference in the concentrations of a substance across a cells membrane?
action potential
How big is nix?

Is it possible to have a triple rainbow across the sky?
no
