Answer:

Cells make up the smallest level of a living organism such as yourself and other living things. The cellular level of an organism is where the metabolic processes occur that keep the organism alive. That is why the cell is called the fundamental unit of life.

Cells are sacs of fluid surrounded by membranes. Inside the fluid float chemicals and organelles. An organism contains parts that are smaller than a cell, but the cell is the smallest part of the organism that retains characteristics of the entire organism. For example, a cell can take in fuel, convert it to energy, and eliminate wastes, just like the organism as a whole can. But, the structures inside the cell cannot perform these functions on their own, so the cell is considered the lowest level.

Each cell is capable of converting fuel to useable energy. Therefore, cells not only make up living things; they are living things. Cells are found in all plants, animals, and bacteria. Many of the basic structures found inside all types of cells, as well as the way those structures work, fundamentally are very similar, so the cell is said to be the fundamental unit of life.

The most important characteristic of a cell is that it can reproduce by dividing. If cells did not reproduce, you or any other living thing would not continue to live. Cell division is the process by which cells duplicate and replace themselves. If you did not replace your red blood cells, for example, you would have a life span only as long as that of red blood cells — a mere 120 days.

Increasingly more complex organisms are made up of increasingly more groups of cells (for example, in humans, groups of cells make up each organ and muscle tissue), and the organisms survive based on products that the cells make. For example, cells in the pancreas make insulin, which is necessary to ensure that the blood glucose level doesn’t skyrocket. Without insulin, the blood glucose can reach a level that is lethal. So, without that cellular product, you would die.

Answer:

1. With his conquest of England in 1066, William I secured for himself and his immediate successors a position of unprecedented power. He was able to dominate not only the country but also the barons who had helped him win it and the ecclesiastics who served the English church. He forced Pope Alexander II to be content with indirect control over the church in a land that the papacy hitherto had regarded as bound by the closest ties to Rome. William’s son Henry I—whose accession (1100) was challenged by his eldest brother, Robert, duke of Normandy—was compelled to make concessions to the nobles and clergy in the Charter of Liberties, a royal edict issued upon his coronation. His successor, Stephen (1135), whose hold on the throne was threatened by Henry I’s daughter Matilda, again issued a solemn charter (1136) with even more generous promises of good government in church and state. Matilda’s son Henry II also began his reign (1154) by issuing a solemn charter promising to restore and confirm the liberties and free customs that King Henry, his grandfather, had granted “to God and holy church and all his earls, barons and all his men.” There developed, in fact, through the 12th century a continuous tradition that the king’s coronation oath should be strengthened by written promises stamped with the king’s seal.

 Rome needed money to run.  

The Republic needed money to pay the legions, to build roads, sewers, aqueducts, and arenas, and to pay for the welfare programs that fed the poor.  To get this money Rome created a system called tax farmers.

A tax farmer was a person who bought the right from the Senate to tax all the people and business in a certain area.  The biggest problem with this system is that the senate didn't set up any controls on the tax farmers.  They didn't say how much taxes were, or who got taxed.  They left all that up to the tax farmer.

Tax farming was a business, and the tax farmers were in it to make a profit.  While most Romans were willing to pay taxes, and even allow the tax farmer some profit, many of the tax farmers went way beyond what people expected.  Many of them saw this as a way to get rich.  Plus, since the tax farmer decided who got taxed and who didn't, you could bribe the tax farmer to make your taxes low or maybe tax your competitors out of business, or if you had enough bribe money, maybe both.  If a Roman citizen didn't pay their taxes at whatever amount the tax farmer set, you and your entire family could be sold into slavery.

Even with the tax farmer system, the Roman government wasn't getting enough money and Rome was going broke.

2.  Elected officials were corrupt.  

Under Roman law you could pay someone to vote for you.  So rich people could actually buy their way into the senate.  Once in the Senate, there were many ways to get huge amounts of money.  Remember the tax farmer?  Since they bought the position from the Senate, the Senate set the amount it cost and decided who actually got the job.  Plus the Senate decided who got to build the roads, arenas etc.  So construction companies bribed the Senate to get the construction contracts.  Finally since the Senate made all the laws, people could bribe senators to make laws that they wanted.  The Government of the Republic was rife with corruption and graft.

3.  Rome was riddled with crime.  Criminals ran wild in Rome.  Since there was no police force, there was no one to stop them.  It was not safe to walk the streets without a guard.  Wealthy Romans hired guards and even built their own small armies to protect their homes and families.  This led to further problems when the guards of one wealthy family fought the guards of another family over insults or business territories.  The Senate couldn't do anything since there was no money to hire police or even create a militia.

There were other problems in Rome to add to these.  Senators didn't trust each other, and they really didn't trust the legions.  They even passed laws making it illegal for a legion to enter Rome.  Rome was a disaster.  The people of Rome were tired of the mess and wanted the problems solved and the corruption ended.  Julius Caesar told the people of Rome that he could solve all of Rome's problems.
