What is a factor that determines whether molecule can cross a cell membrane?
size/ polarity can be the factors
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.

size and shape. cell membranes are selectively permeable, so only some molecules can get through. (i.e. water can go through, but starch cant) Polarity and size.
Does the size or the speed of a molecule determines whether it can pass through the pores of a membrane?
The speed doesn't necessarily determine the permeability, but the size does. Smaller molecules such as O2 can easily enter the cell while CO2 leaves the cell. There are other criteria that also determines whether a molecule can pass through the plasma membrane such as its solubility. Fat soluble molecules such as steroids can easily pass through the membrane.
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.

What two thing determine whether or not a molecule is polar?
The shape of the molecule and The electronegativity differences of atoms in the molecule

What does permeability depend on?
Permeability depends on membrane solubility and the presence of specific integral transport proteins. Other factors such as pressure, concentration, and temperature of the molecules or solutes on either side, as well as the size of the molecules can also affect permeability.
What is a factor that deteremines whether a molecule can cross a cell membrane?
Usually its size and net charge.
