What are concentration gradients?
Concentration gradients is a solutes. This is used in the body.
How do you define osmosis?
Osmosis is the movement of water across a selectively permeable membrane in a response to gradients of concentration, pressure, or temperature. I got this from my Biology textbook.
What concentration gradients are established and maintained by the sodium potassium exchange pumps?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
Does room temperature affects concentration?
Temperature affects oxygen concentrations directly. When the temperature increases, oxygen concentration will decrease. In low temperatures, oxygen has higher concentration levels .
When osmosis do not occur?
Osmosis across the cell membrane doesn't occur when the concentration gradients, and therefore the water potential inside and outside of the cell are the same
What are concentration gradients?
Concentration gradients is a solutes. This is used in the body.
Which affects the rate of diffusion through a semipermeable membrane?
steeper concentration gradients, higher temperatures and size of the molecule diffusing
How does gradient affect diffusion?
A concentration gradient is a difference in concentration across a space. It affects diffusion and osmosis because both of these passive transports move down their concentration gradients, or from an area of high concentration to low concentration.
How are concentration gradients maintained for diffusion?
Passive transports such as diffusion and osmosis move down their concentration gradients.
Which affects the rate of diffusion through a semipermeable membrane steeper concentration of gradients higher temperatures or the size of the molecule diffusing?
all of thouse factors
What affects the rate of diffusions?
Temperature, Concentration and size of molecules :)
What three things can affect the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
How do you define osmosis?
Osmosis is the movement of water across a selectively permeable membrane in a response to gradients of concentration, pressure, or temperature. I got this from my Biology textbook.
In what direction do particles natural diffuse?
Down concentration gradients.
What initiates air flow?
Temperature gradients
What affects the setting time of concrete?
The liquid content temperature its concentration and the area's environment being concreted
What is the pumping of materials across a membrane against their concentration gradients?
Active Transport
