Molecules, due to constant thermal motion, enables them to move from one region to another with a velocity that depends on their mass, shape, the temperature and viscosity of the medium.
Brownian motion is also a factor - this is where the bombardment of the molecules are taken into consideration (colliding with one another).
What else can I help you with?
Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
How do you describe the motion of atoms in a solid?
Atoms move more freelythan they would in a soild or a liquid.
What is the term used to describe the spread of molecules throughout the area?
Epitome spreading is the act of molecules self spreading. It can also be called mimicry. This is when molecules seem to mimic other molecules, but are replicating themselves.
Form of a diffusion in membrane through fluid is what?
The form of diffusion in a membrane through fluid is passive transport. This process does not require energy input and allows molecules to move from an area of high concentration to an area of low concentration. It occurs naturally as a result of the random movement of molecules.
How do water molecules move through the cell membrane during omosis?
With a specific channel protein called aquaporins.
How do molecules move in fluid?
Molecules move in a fluid the same way they move through anything else. If the fluid is warmer, they move faster.
Describe the water molecules move through the cell membrane during osmosis?
Describe how water molecules move through the cell membrane during osmosis?
What happens to molecules in a heated fluid?
In a heated fluid, molecules gain kinetic energy, causing them to move faster and collide more frequently. This increased movement results in the expansion of the fluid, as the molecules move apart from each other. Additionally, the increased temperature can lead to changes in the physical state of the fluid, such as boiling or evaporation.
What is the name of the model developed by scientists to describe the arrangement of molecules within this structure?
The model is called the fluid mosaic model. It describes the structure of cell membranes as a fluid lipid bilayer with embedded proteins that move freely within the membrane.
Describe what is happening to water molecules as ice melts?
they move faster
What happens to a fluid when it heats?
When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules. When the liquid molecules are heated, they move faster so the liquid boils and some molecules becomes gas molecules.
Why does viscosity vary with respect to temperature?
the increase in temperature increases the K.E of the molecules and distances among molecules therefore the force of friction decreases as the result of which molecules move faster and viscosity becomes decreased....
Because the phospholipid molecules and some proteins are free to move the plasma membrane is said to be?
Because the phospholipid molecules and some proteins are free to move, the plasma membrane is said to be fluid, allowing for flexibility and dynamic changes in its structure. This fluidity is essential for various cellular processes such as cell communication and transport of molecules across the membrane.
How do molecules move in a fluid?
Small particles or molecules suspended in a liquid or gas will move by what is called Brownian motion. Brownian motion is a random motion of particles resulting from collisions with other matter. Unless otherwise disturbed, Brownian motion will eventually diffuse the suspended particles evenly throughout the liquid or gas.
How can you Describe how molecules move in each of the three states of matter?
In the solid state, molecules vibrate in fixed positions. In the liquid state, molecules have more freedom to move around but are still closely packed together. In the gas state, molecules move freely and rapidly, with very weak intermolecular forces.
Explain why the term fluid mosaic model is used to describe the plasma membrane?
the arrangement of the molecules that make up a cell mebrane
What happens to a fluid when it cools?
When a fluid cools, its molecules lose energy and move more slowly, causing the fluid to contract and become denser. Eventually, the fluid may reach its freezing point and solidify into a solid state.
