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.

What is a factor that determines whether molecule can cross a cell membrane?
size/ polarity can be the factors
Which two factors of the molecule determine whether or not it can cross the membrane?
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.
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.
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.
What factors determine where an organism lives?
Biotic factors help determine where specific organisms live

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 is a factor that determines if a molecule can cross a cell membrane?
size/ polarity can be the factors
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.
What are the factors that determine whether observational learning will occur?
The key factors that determine whether observational learning will occur include attention, retention, motor reproduction, and motivation. Attention refers to the extent to which individuals focus on the model's behavior. Retention involves remembering the observed behavior. Motor reproduction is the ability to replicate the behavior, and motivation relates to the desire to imitate the behavior based on reinforcement or punishment.
