What are some characteristics of facilitated diffusion?
The substances are moving from areas of high concentration to areas of low concentration with the help of a protein channel.
What is the Relationship solute concentration solvent concentration in osmosis?
In any situation, the more concentrated a solution is in terms of solute, the less concentrated it is in terms of solvent. This is important in osmosis as you have to be careful which way round you express things, because it is water which moves from where there is a lot of it to where there is less. Thus you have to understand that if you have a high concentration of sugar, you have a lower concentration of water.
What type of osomosis does tap water have?
Osmosis is the diffusion of water molecules. You may be thinking about the filtration method termed "reverse osmosis". The movement of water depends on the difference in solute concentration ocross a selectively permeable (lets water in/out) membrane. So the osmosis of tap water depends on its solute concentration relative to the other side of a membrane. In general, water moves from areas of high concentration to low concentration. This is why cabbage wilts when placed in salty water (more solutes in salty water means lower concentration of fresh water relative to the plant cells, so water leaves the cabbage as the cells become flaccid).
How your lungs refine oxygen from other gases?
Your lungs refine oxygen from the other gases in air because the gases diffuse through the cell walls in the alveoli in your lungs through osmosis (higher concentration of gases in the air than in the blood, so gases move from the higher concentration to the lower concentration) where they contact the red blood cells. The hemoglobin in the red blood cells binds to the oxygen and leaves all the other gases alone. It moves on from the lungs and delivers the oxygen to the rest of the body. It's the hemoglobin that does the work.
What type of tissue moves the chicken wing?
it is the tendon tissue it moves the chicken wing
How much energy is lost as energy moves up trophic levels?
10 percent
How do transport proteins that are pumps differ from that are channels?
Transport proteins that are pumps differ from those that are channels in that when it pumps, it moves materials against concentration gradient. Other wise, from low to high concentration levels. Channels move materials down a concentration gradient, requiring no energy expenditure by the cell. From high concentration to low concentration levels.

How much energy moves from one trophic level to the next?
Only 10% moves up...my daughter is writing a paper on this now!
What happens to the other 90 percent in the 10 percent rule?
in the ten percent rule the other 90% gets stuck in the trophic level while the other 10% moves on to the other levels.
What moves through organisms at each trophic level of an ecosystem?
nutrients
What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The concentration gradient is controlled by Diffusion. This same movement in reverse is known as Osmosis.
Why are matter and engery transferred through an ecosytem?
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
What happens to the amount of energy that is transferred from one trophic level to the next?
At the base of the food chains lies the primary producers. Primary producers are principally green plants and certain bacteria. They convert solar energy into organic energy. Above the primary producers are the consumers who ingest live plants or the prey of others. Decomposers, such as, bacteria, molds, and fungi make use of energy stored in already dead plant and animal tissues.
Besides energy what moves through the organism at each trophic level of an ecosystem?
nutrients
What is the description of passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
What is a process by which molecules moves from a high concentration to a low concentration?
Osmosis
