There is no "site". Import and export of molecules is regulated by receptor proteins and the concentrations of these proteins. Concentration gradient is also important for small molecules.
Yep
It is the site of photosynthesis.It produces food for plant.

In the cell, the endoplasmic reticulum which contain ribosomes is the site for protein synthesis. Afterwards, the proteins undergo the translation process.
In simple terms, the mitochondria are the site of energy production in the cell.
Mitochondria is the powerhouse of a cell.

You can define a cell site as a single site that has a cell phone traffic through the single site. You can find this information online in encyclopedias such as Wikipedia.
The site FCC gov is the official site of the Federal Communications Commission. The Federal Communications Commission is the organization that regulates interstate and international communications.

The cell membrane regulates the passage of chemicals in or out of the cell. It is made up of a phospholipid Bi-layer consisting of many lipids much like the ones found in a detergent (Hydrophillic heads and hydrophobic tails). The tails avoid water and stay together - this makes a water proof barrier. A cell membrane is known as partially permeable as it allows non-polar molecules (or very small polar molecules such as CO2) to pass through but stops larger polar molecules, H2O for example, from passing, this is useful as it prevents excessive water loss from the cell. The cell membrane is more detailed but for your question there is no need for that.
Yes it does. This site here will give you a run down on what its used to treat people with http://www.experiment-resources.com/stem-cell-pros-and-cons.html.
sparkworkz.com (which is the site that hosts the game) sometimes goes down, meaning you can't access the games on the site. This has been happening less frequently though.
it occurs in three stages. stage 1:in this it(current cell site) searches for the new cell site near to it(not allocated channel). stage2:in this it confirms whether a cell site is ready for hand off. stage3:in this the hand off occurs. if it does not get any response from the cell site(in stage 2) which it is looking for then it prefers for another,if no cell site is ready for hand off,the signal will be continued by the current cell site till the stage3 and later the signal is lost.
The primary site for blood cell production is the bone marrow.
The standards site regulates schools in the UK. They set examples of good practices held in schools and they offer guidance. Their main area of concern is in literacy.
