What are capillary transport mechanism?
Capillary transport mechanisms refer to the movement of fluids through capillaries by processes such as diffusion, filtration, and osmosis. These mechanisms help to transport nutrients, gases, and waste products to and from cells in the body. The exchange of substances across capillaries is essential for maintaining proper tissue function.
What are the key differences between active transport and facilitated diffusion in terms of their mechanisms of movement across cell membranes?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules move down their concentration gradient across the cell membrane.
What are the similarities between active transport and facilitated diffusion in terms of their mechanisms of transporting molecules across the cell membrane?
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
How does passive diffusion differ from facilitated diffusion in terms of their mechanisms of transport?
Passive diffusion and facilitated diffusion both involve the movement of molecules across a cell membrane, but they differ in their mechanisms of transport. Passive diffusion does not require the assistance of transport proteins and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion, on the other hand, involves the use of specific transport proteins to help molecules move across the membrane, typically from an area of high concentration to an area of low concentration. In summary, passive diffusion is a simple process driven by concentration gradients, while facilitated diffusion involves the assistance of transport proteins for more efficient movement of molecules.
What are the three forms of passive transport and how do they differ in their mechanisms of movement across the cell membrane?
The three forms of passive transport are diffusion, facilitated diffusion, and osmosis. Diffusion involves the movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion uses protein channels to help molecules move across the membrane. Osmosis is the movement of water molecules across a selectively permeable membrane.
What is a Diffusion is the movement of a substance?
diffusion is the movement of materials into cell membranes when the outside of the cell has a higher density than the inside
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
Are aquaporins involved in osmosis or facilitated diffusion?
Aquaporins are involved in osmosis by facilitating the movement of water molecules across cell membranes. They do not participate in facilitated diffusion, which involves the transport of solutes across membranes with the help of carrier proteins.

What are two similarities and two differences of osmosis and diffusion?
Similarities: Both osmosis and diffusion involve the movement of molecules across a semi-permeable membrane. Both processes occur due to a concentration gradient, moving from an area of higher concentration to lower concentration. Differences: Osmosis specifically involves the movement of water molecules across a semi-permeable membrane, while diffusion involves the movement of any type of solute. Osmosis is the movement of water molecules to equalize the concentration of solutes on both sides of the membrane, whereas diffusion is the movement of solute molecules to reach equilibrium.
What is the movement of particles from an area of higher concentration to an area of lower concentration where membranes are not concerned?
The movement of particles from an area of higher concentration to an area of lower concentration without the involvement of membranes is known as diffusion. This process occurs due to the random motion of particles, leading to a net movement that continues until equilibrium is reached. Diffusion can happen in gases, liquids, and even solids, and it is driven by the concentration gradient.

What are the differences between convection and diffusion in terms of their mechanisms of heat transfer?
Convection involves the transfer of heat through the movement of fluids, such as air or water, while diffusion involves the movement of heat from areas of high concentration to areas of low concentration without the need for fluid movement.
What is diffusion a natural movement of molecules from?
in the normal diffusion the substance move from the area of greater concentration to that of lower concentration. .... but i never know what do we mean be "faciliated" plz specify
