No, although it is specific and faster, it is still diffusion.
Exocytosis=) need more? i'll be glad to help! just add Dylan Wilkerson on facebook!=)
The kidneys are responsible for filtering blood, regulating fluid balance, and removing waste products from the body. These activities require a lot of energy to maintain, as the kidneys need to continuously work to perform these essential functions. Additionally, the kidneys have a high blood flow rate, which also contributes to their energy demands.
Yes, all living things require energy to survive.
Simple diffusion = flow of small molecules ALONG the concentration gradient, does NOT require energy. facilitated diffusion = flow of molecules ALONG the concentration gradient with help of CARRIER PROTIENS or CHANNELS, does NOT require energy active transport= flow of larger or charged molecules AGAINST their concentration gradient, REQUIRES input of ENERGY in the form of ATP.)
In passive transport processes, no energy is required because molecules move across the cell membrane from an area of high concentration to an area of low concentration, following the natural flow of diffusion. This movement occurs spontaneously and does not require the cell to expend energy.
Diffusion is the movement of substances from an area of high concentration to low concentration, while bulk flow is the movement of substances in a fluid due to pressure differences. Diffusion occurs passively, while bulk flow requires energy.
Yes because energy gives us energy, energy gives us cancer. I'm not a 100% positive though.
Yes, pumps require energy to operate. They use mechanical energy to move fluids from one place to another, such as water in a pumping system or air in a compressor. The amount of energy needed depends on factors such as the flow rate and pressure required by the pump.
Pressure gradients drive bulk flow by creating a difference in pressure between two points, causing the movement of fluids from high pressure to low pressure areas. The greater the pressure gradient, the faster the bulk flow of fluids will occur.

Active transport: The movement of particles against the concentration gradient into or out of a cell. Bulk transport:The movement of large molecules into or out of the cell. Both of these require energy
The bulk flow of filtrate is a type of diffusion. Diffusion is a broad category of distribution of a substance within another substance. Diffusion can be specific or general in location and rate of flow.
Pressure Gradient
if there is convective flow or bulk flow or random mixing of molecules ,eddy diffusion will occur.
no it does not require energy.
Convection is the mode of heat transfer, referring to the transfer of heat energy due to bulk motion of a fluid."Convection current" is the name of that bulk motion of the fluid, the transfer of MASS. I prefer to call it buoyantly driven flow. It doesn't flow due to convection, convection is due to if flowing. It flows due to buoyancy in the case of free convection.Peyton
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
