diffusion
Passive transport occurs when substances cross the plasma membrane without any input of energy from the cell. No energy is needed because the substances are moving from an area where they have a higher concentration to an area where they have a lower concentration. Concentration refers to the number of particles of a substance per unit of volume. The more particles of a substance in a given volume, the higher the concentration. A substance always moves from an area where it is more concentrated to an area where it is less concentrated. It's a little like a ball rolling down a hill. It goes by itself without any input of extra energy.
Under normal circumstances, chemical concentrations in any given solution tend to even themselves out, by diffusion, and by the normal process of entropy. Cells often need to have a higher concentration, or a lower concentration of some chemical (which is a solute, because it is dissolved in water) than the concentration that exists outside the cell in the intercellular fluid, the lymph, the blood, or the cerebro-spinal fluid, as the case may be. In order to obtain that difference in concentration it is necessary to have some mechanism in the cell membrane that will actually pump the chemical in question, either out of the cell or into the cell, depending upon whether it is a higher concentration or a lower concentration that is needed. So, there are protein structures that can do this. Those are the solute pumps.
during cellular respiration organisims take in oxygen from their surroundings and combinet with sugar and other carbon containing substances to release enrgy tored in them. during cellular respiration organisims give off carbon dioxide gas in to there surroundings, during this prosess water is given of into the surroundings to!
Glucose and oxygen are used up during respiration.
Nitrogen fixation
KDIE
This is the concentration of a solute in a solvent at a given temperature and pressure.
It is not true. All substances tend to diffuse from an area of higher concentration to that of lower concentration. This is called passive transport(no energy required), or in the case of water, Osmosis. However, if given energy, they can also move from an area of lower concentration to that of higher concentration. This process is called active transport.

acidic, alkaline higher than 7
"Which" indicates that you were given alternatives to chose from. Without knowing those, we can't help you.
Refuse the order and report to higher authority.
Hydrothermal alteration.
Relative concentration gives you a comparison of two or more solutions, telling you which has a higher concentration of some solute than the other. Precise concentration would normally be expressed in terms of moles per liter, and it tells you the actual amount of a solute that is present in a given volume of solution.
A Liquid that conducts electricity and is decomposed in the process is called electrolyte.
How? Molecules move from an area of higher concentration to an area of lower concentration. When the concentration decreases (be it determines by a measure of pressure) in a unit volume; that indicates there are less molecules occupying that given space. So they must have gone somewhere...
The rate of the forward reaction will increase if the concentration of the reactants is increased.This is explained by collision theory. When there are more molecules in a given space (a higher concentration) with the same energy, the molecules will collide more frequently, since they will move about randomly and are more likely to hit one another if there are more of them around and less empty space. A reaction requires a collision, so more collisions in a given amount of time will lead to more molecules reacting in that time, giving a higher rate of reaction overall (in the forward direction).
