Which feature of a memebrane describes whether molecules can cross the membrane?
permeability
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 best determines whether a molecule crosses a cell membrane?
The ability of a molecule to cross a cell membrane is primarily determined by its size, polarity, and charge. Small, nonpolar molecules, such as oxygen and carbon dioxide, can easily diffuse through the lipid bilayer. In contrast, 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 further influence a molecule's permeability.

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 hydrophilic a property that determines whether a molecule is polar or nonpolar?
Yes, hydrophilic is a property that determines whether a molecule is polar or nonpolar. Hydrophilic molecules are polar, while hydrophobic molecules are nonpolar.
