(CNN) -- English club Chelsea have completed the signing of Oriol Romeu from Spanish and European champions Barcelona. The 19-year-old is currently playing for Spain at the World Under-20 Championships in Colombia and has signed a four-year deal with last season's Premier League runners-up. The deal is worth $7 million and includes a buy back clause, set at $14 million after the first year and $21 million after the second. Romeu started his career at Barcelona's city rivals Espanyol before joining the Camp Nou academy in 2004. The midfielder, who can also play in central defence, made his debut for Barcelona in last season's Spanish Supercup match with Seville and got his first taste of league action against Deportivo in May 2010. He has played 90 minutes in both of Spain's games at the World Under-20 Championships, when they beat Costa Rica and Ecuador. Chelsea official web site confirmed the signing and said Romeu is "renowned for his strength and his expansive passing ability." Another player leaving Barcelona is Jeffren Suarez after he agreed to join Sporting Lisbon. The Portuguese outfit have paid $5 million for the 23-year-old which, like the Romeu deal, includes a buy back option. Jeffren joined Barca from Tenerife in 2004 and made his debut for the Catalan club in the 2006-07 season.

Tropical climates are found around the equator. These climates have warm temperatures year round. Tropical climates may be very wet or wet and dry. Tropical wet climates occur at or very near the equator. They have high rainfall year round. Tropical rainforests grow in this type of climate. Tropical wet and dry climates also occur near the equator. They receive less rainfall. Most of the rain falls in a single season. The rest of the year is dry. Few trees can withstand the long dry season. The main plants are grasses. Dry climates receive very little rainfall. They also have high rates of evaporation. This makes them even drier. Deserts can get less than 25 centimeters of rain per year. Thats less than 10 inches per year. How much rain do you get at your house?

The digestive system is the body system that digests food. It digest food in two ways, mechanically and chemically. Both help in the process of turning food into nutrients. The digestive system also eliminates solid food waste. The major organs of the digestive system include the mouth, esophagus, stomach, and small and large in- testines. These organs all work together to help you gain energy from the food you eat. Digestion starts in the mouth. When food is swallowed, it travels through the esophagus to the stomach. In the stomach, digestion continues and a small amount of absorption of nutrients takes place. Most chemical digestion and nearly all absorption of nutrients take place in the small intestine. This organ consists of three parts: duodenum, jejunum, and ileum. The large intestine is the last stop in the digestive system. This is where water is absorbed. The food not digested is released as waste.

Nine families displaced by a fire at Alamo Hills Apartments in March filed lawsuits Wednesday against the apartment complex. They allege that the complex could have done more to protect belongings they were forced to abandon in the aftermath of the blaze. Bernard Dempsey Jr., an attorney with Western Michigan Legal Services, the group that represents the tenants, said Alamo Hills gave the displaced families very limited opportunity to remove belongings. "They were given three days to get their stuff out, and if they couldn't get moved out in three days, their stuff was discarded," Dempsey said. "Alamo Hills just threw it out." Others, he said, lost possessions to looters after the March 23 blaze, which left 78 people temporarily homeless. According to the lawsuit, the tenants were prohibited from entering their apartments to retrieve possessions and were promised that the complex would provide security. A spokesperson for PM One, the company that manages Alamo Hills, could not be reached for comment. Nine separate suits were filed in 8th District Court, which handles civil claims of less than $25,000. "We're asking for the reimbursement of the value of their property and a small amount for stress -- $3,000 on top of their out-of-pocket expenses for their lost stuff," Dempsey said. "They're not looking to get rich off this. A lot of this is simply because they were treated so badly." Dempsey said most of the tenants who filed suits still live at the apartment complex, although many are trying to find homes elsewhere. "The new apartments (they were provided) were not in very good shape. That's actually one of the claims," he said.
