Is osmosis a passive or active transport and how?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Osmosis always deals with the movement of water across a semipermeable membrane. Water always moves toward the side that is higher in solutes (mainly salt). It does this to balance the two sides. Osmosis always follows salt is one of the best ways to remember this.
Is voltage an excess accumulation of electric charge?
Sort of ... 1) Voltage is ALWAYS a comparison, thus it requires two reference points. 2) Its the density of the charge that counts, thus a gigantic charge over a very large area would result in a low voltage.
What is a sentence using the word always?
Always try to frame your sentences properly. I will always do my best. We won't always be here to watch over our children. Honesty is always the best policy.
What is research always?
research is always informative.
Are Trial and error is discouraged in science because it wastes time?
Yes. Blind (without hypothesis) experimenting, while occasionally producing useful data, is normally a real time waster. This is because data obtained from blind experimenting almost always requires a rigorous confirmation process anyway, before it can be used in scientific work.
True or false active transport always requires transport proteins during the process?
true
Active transport always requires transport proteins during the process?
false
Is the following sentence true or false active transport always requires transport proteins during the process?
false
What form of passive transport always requires membrane-bound proteins?
Facilitated diffusion
Which process always involves the movement of materials from inside the cell to outisde the cell?
There are several processes that it could be. It could be active transport, passive transport, and also endocytosis.
Does pinocytosis require ATP?
I think so, because pinocytosis is always active transport and that requires ATP. But I'm not 100% sure
Osmosis is what type of transport?
Diffusion. It's the movement of water through a permeable membrane. And it's always passive.
What is the different between passive and active transport?
One difference is energy consumption. Active transport requires the cell to expend energy, while passive transport does not. Active transport is movement from a lower concentration to a higher concentration and passive transport is movement from a higher concentration to a lower concentration. Active transport is the movement of molecules across a membrane requiring energy to be expended by the cell. Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Active transport requires ATP to transport materials. Passive transport does not require ATP input to transport materials. Ex: diffusion
Difference between metabolic extension and metabolic engineering?
Metabolic engineering is the manipulation of metabolic pathways and cellular networks in a cell in order to increase the production of a certain substance via optimizing genetic and regulatory processes. It involves the introduction of heterologous genes and regulatory elements which leads to targeted alterations in normal cellular activities; the cell that has been most successfully altered to produce various products in high supply is Escherichia Coli (E Coli). As for Metabolic extension? I'm not that sure, but hey, you can always check Wikipedia! ;)
What are all the differences between active and passive transport?
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
What is the difference between passive active transport homeostasis?
Active transport is the movement of molecules across a membrane requiring energy to be expanded by the cell.ACTIVE TRANSPORT REQUIRES ENERGY.Passive transport is diffusion across a membrane requiring only random motion of molecules with no energy expanded by the cell. Osmosis is an example of this.PASSIVE TRANSPORT REQUIRES NO ENERGY.Other answersActive transport requires energy often, in a cell, in the form of ATP (adenine triphosphate), like a sodium-potassium channel in a cell.Passive transport happens without the use of energy. An example of this is osmosis.Active transport is the movement of solutes against concentration gradient or electrical gradient. The solutes pass from a low solute concentration to a higher solute concentration, therefore it is also known as "uphill transport" whereas, Passive Transport is the movement of solutes towards the concentration gradient or electrical gradient. The solutes pass from a high solute concentration to a low solute concentration, therefore it is also known as "downhill transport".Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy.

When stuff diffuses why does it always go to a less concentrated area?
When matter diffuses through a cell it moves from an area of higher concentration to an area of lower concentration. This process is called passive transport, which requires no energy. Opposite to that, active transport requires energy, or ATP, because it is moving things from an area of lower concentration to higher.
