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 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.
What factor affects the the change in temperature when a salt is dissolved in water?
The binding energy of the molecule compared to the binding energy of the ions it splits into when it is dissolved determines the change in heat of the water. The stronger a molecule is bound, the higher its binding energy and the more heat is needed to break it apart, which cools the water.
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 factor other than electronegativity determines whether a molecule as a whole is polar or not?
The shape of the molecule is a big indicator. If the molecule looks like it has some symmetry to its shape, and its poles are directly opposite of each other, then there it`s a good bet that it`s non polar.

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.

What is a factor that deteremines whether a molecule can cross a cell membrane?
Usually its size and net charge.
State one factor that influences which molecules can pass through the cell membrane?
Responses include, but are not limited to:molecule size; concentration of molecules; pore size; carrier proteins; molecule charge/shape.
If an argument is valid, then what is the key factor that determines its soundness?
The key factor that determines the soundness of an argument is the truth of its premises.
What is the primary factor that determines the velocity of a wave?
The primary factor that determines the velocity of a wave is the medium through which the wave is traveling.
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.
