What role does a cellular membrane play in active transport?
Active transport is the name given to the process of using energy to move substances into cells against what would happen without the expending of energy. Think of an island you want to visit. It is too far away to have a bridge so t is required to expend more energy than usual to get there--either by boat or plane, for example. Osmosis or diffusion account for movement of substance within another substance or across a membrane. It could be argued that there is energy involved in these movements, but no ATP is used. Active transport requires either ATP or electrochemical potential for movement. Sometimes, active transport moves substances against a concentration gradient. In the case of roots, the concentration of "fertilizer" or ions in the soil may be far less than in the tissues of the roots, yet active transport allows more ions to enter the roots. This is the method of obtaining glucose, for example, from your intestinal contents in the cells of the intestine. Active transport is like a ferry, but you have to pay the ferryman to gain passage.
What might happen to an organism if it has to compete for its source of energy?
It might get enough energy for its needs, or it might not.Note that this is the usual situation - there are usually other organisms, with which an organism has to compete.
How does the coal source work?
The energy in coal is chemical energy. The usual way to extract it is to burn the coal converting it to heat energy. This can then be turned into electrical energy Fuels like gasoline and coal are sources of energy which means they store energy
What is the most common source of fraction?

How do you get to Venice from Frankfurt?
By all the usual methods of transport: fly, by train, drive.
How do you compare solar energy and wind energy?
Both are renewable. That's the the usual term but it's a dreadful one because energy is not "renewable". They are to all practical purposes inexhaustible instead, and they share one source: the sun's heat which then drives the weather systems.
What is the usual reason that Stereo speakers will not all play?
A: Make sure your source is has a stereo source.
What is the structure in the human body that is the usual source of insulin?
Pancreas
