Each tonsil consists of a network of crypts (pits) that store cells used to fight infection. The tonsils contain B cells, a type of white blood cell that fights infections. They also produce antibodies against polio, streptococcal pneumonia, influenza, and numerous other infections.
Global Warming: What's Up With The Weather? is a DVD presentation of the television special by NOVA and Frontline dealing with questions raised about modern climate change.
Think about it this way: Climate is what you expect, weather is what you get. Weather is what you see outside on any particular day. So, for example, it may be 75Â° degrees and sunny or it could be 20Â° degrees with heavy snow. Thatâs the weather. Climate is the average of that weather. For example, you can expect snow in the Northeast in January or for it to be hot and humid in the Southeast in July. This is climate. The climate record also includes extreme values such as record high temperatures or record amounts of rainfall.
