What is a factor that determines if a molecule can cross a cell membrane?
size/ polarity can be the factors
What factor influences the strength of the response in the receiving cell?
it would be the strenght of the stimulus
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
What factor influences the early detection of a childhood disease by a physician?
How close the doctor office is APEX
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 a factor that determines whether a molecules can cross a cell membrane?
mass
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.
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.
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.
What are the factors influences span of control?
factor's which influences span of control. factor's which influences span of control.
What are the Factors which influences span of control?
factor's which influences span of control. factor's which influences span of control.
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.
Which is a factor that determies whether a mole can cross a cell membrane?
Lipid solubility determines if it will diffuse across. The presence of specific protein carrier molecules determines if it will be transported across the membrane.
Is mood a factor that influences BAC?
no
Why molecules move into and out of cells?
Molecules move in and out of the cell by difffusion process and only those molecules which have size smaller then pore size of plasma membrane can move in and out of the cell. The second factor is ionic conc or is also known as conc gradient according to which molecules of required ionic status can move in and out of the cell
An improvement in technology is a factor that influences?
supply
