What is a factor that determines if a molecule can cross a cell membrane?
size/ polarity can be the factors
What membrane does diffusion is the flow of water from high concentration to low concentration?
Osmosis is the tendency of water to flow from high concentration to low concentration. Osmosis, gravity, pressure, and matrix effects (cohesion, surface tension, etc.) all factor into the final water potential.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
What is a limiting factor to cell size?
the ration of volume to cell surface is the biggest factor. if it gets too big, it will take too long to transport necessary molecules form the cytoplasmic mebrane or nucleus out to the environmment or vica versa. size is usually regulated by genes encoded in the DNA.
What is most important factor that influences the concentration of life is?
The most important factor that influences the concentration of life is the availability of resources like food, water, and shelter. These essential resources determine the ability of organisms to survive, grow, and reproduce within a given environment. Without adequate resources, life forms cannot thrive and populations may struggle or decline.
What is a factor that determines whether a molecules can cross a cell membrane?
mass
What are two factors that determine whether or not molecules can pass through a selectively permeable membrane?
One factor is the channel of the molecule, without them the ions and polar molecules would not be able to pass across. Another factor is the size of the molecule, they determine how fast it will defuse.
How do other molecules pass through the selectively permeable cell membrane?
[Molecules pass through the cell membrane] through a process known as osmosis. ------------------------------------------------------- Yes, osmosis is a great part of diffusion of molecules, but another important factor to consider is the presence of protein channels in the membrane. The cell membrane is actually a lipid bilayer, in which proteins are embedded. Normally, molecules will simply be diffused through these chanells, but in some cases, the protein must be modified in order to allow the molecules to flow. This is called active transport, which requires energy in order to change the shape of the protein and allow the foreign molecule to pass.
What part of the cell acts like a selective filter and determines what goes in and out of the cell?
The plasma membrane is selectively permeable, allowing certain molecules to travel in and out of the cell. The size, PH, and temperature all play a factor in what molecules travel through the membrane or don't.
Ask us is a factor that determines whether a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, like oxygen and carbon dioxide, can easily diffuse through the lipid bilayer, while larger or polar molecules often require specific transport proteins or channels to facilitate their passage. Additionally, the concentration gradient and the presence of membrane proteins can also influence a molecule's ability to cross the membrane.
What factors influence the passage of substances through living membranes?
One factor that influence the passage of substances through living membranes are size which small molecules pass faster than large. Others are the charge non polar are faster and concentration gradient molecules that move to regions of lower concentration.
Which is a factor that determines wheathe a molecule can cross a cell membrane?
A key factor that determines whether a molecule can cross a cell membrane is its size and polarity. Small, nonpolar molecules, such as oxygen and carbon dioxide, can easily pass through the lipid bilayer, while larger or polar molecules often require specific transport proteins to facilitate their movement. Additionally, the concentration gradient and the presence of channels or carriers also influence a molecule's ability to cross the membrane.
Which factor prevented the protein molecules from moving out of the cell?
The presence of the cell membrane acts as a physical barrier that prevents protein molecules from moving out of the cell. The cell membrane is selectively permeable, controlling the movement of substances in and out of the cell. Additionally, certain proteins within the cell membrane help to regulate the transport of molecules.

Why are cellular transport and cellular communication factors that limit cell size?
The cellular transport and cellular communication factor that limit the cell size because all the materials that go in and out of a cell must pass through the plasma membrane.
