What else can I help you with?
What helps moves things across the membrane?
transportation
Which one moves faster across the cell membrane the large or the small?
Small particles move faster across the membrane.
How does the material move from the respiratory system to the circular system?
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
When water moves across a cell membrane it is called?
osmosis
What is the proccess by which water moves across a cell's membrane?
Passive diffusion.
What is it when water moves across a cell membrane?
When water moves across a cell membrane, it is called osmosis. Osmosis is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane.
What moves marerials across the plasma membrane in the direction of the concentration?
Active transportation is the material that across plasma membrane. This makes it flow one way.
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
Passive transport is a non-energy requiring process that moves materials across a cell membrane with the concentration gradient. This process includes simple diffusion, facilitated diffusion, and osmosis.
What molecule moves across the membrane During osmosis?
Water molecules move across the membrane during osmosis. Osmosis is the movement of water molecules from an area of lower solute concentration to an area of higher solute concentration across a semi-permeable membrane.
What is the process which water moves across the cells membrane?
Water moves across the cell membrane through osmosis, which is the passive movement of water molecules from an area of higher concentration to an area of lower concentration through a selectively permeable membrane. Osmosis helps maintain the balance of water and solutes inside and outside of the cell.
Osmosis in cells?
it occurs when water moves across a membrane to a lower concentration from a higher concentration.
Which process moves an ion across a cell membrane against a concentration gradient?
ative transport
