Many organisms acquire necessary nutrients, such as minerals, in the form of ions, by transporting these chemicals into cells against the concentration gradient. Describe the ways in which this process occurs. Be sure to
they were active.
Since is used in active voice wheras ever since is used in passive
active- they can shout and squirm but can't kick passive- they cannot shout because they're submerged or face down and have stopped moving
For passive equipment ome kind of electronic warfare jammer, although if you wnated to shoot something you'd need active gear like AAA.
There was passive and active resistance. Active reisitence was generally focussed towards times of a co-ordinated action. Passive took the forms of 'going slow' or creating extra problems that wasted time.
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
Active Transport is the passage of materials across the membrane through the expenditure of energy. Passive Transport is the passage of materials across the membrane without the expenditure of energy. Bulk Transport is the type of active transport. Diffusion and Osmosis are type of passive transport.

In passive transport the solute is driven across the cell until both sides of the membrane are equal. In active transport, energy causes the transporter to release the solute to only one side of the membrane.
Active transport is ATP dependent, whereas passive transport uses only the kinetic energy of the particles for movement across the plasma membrane- mastering A and P homework-
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.
An example of passive transport would be the process of osmosis (water diffusing between a membrane-- from an area of high concentration to an area of low concentration). It is known as passive transport because no energy is needed in order to move the water across the membrane. When no energy is needed to move the substance it is considered passive transport. On the other hand, when energy IS needed to transport molecules or substances across a membrane it is referred to as active transport. An example of this would be a calcium pump located in the lipid bilayer of a plasma membrane which can transport potassium (K+) ions across it. Energy is needed in order to move those potassium ions across the membrane, and therefore is referred to as active transport.

Osmosis, Passive Transport, and Active Transport
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable membrane.
