Since polystyrene disintegrates slowly, one of the main challenges that it poses on the environment is that exposure to the sun causes it to photodegrade, meaning it breaks apart into smaller and smaller pieces. The broken down material ends up looking like food to small animals.
United States Congress elections, 2016. A total of 469 seats in the U.S. Congress (34 Senate seats and all 435 House seats) were up for election on November 8, 2016. The big story of the 2016 congressional election cycle was whether or not the Democratic Party would be able to regain control of the Senate.
All 435 seats in the House of Representatives are up for re-election every two years during even numbered years. Members serve two-year terms. Senators serve six-year terms. Approximately one third of the Senate is up for re-election every two years.ach Congress is two years in length, consisting of two sessions. For example, in the 107th Congress (2001-2002), 9,130 bills and joint resolutions were introduced. Only 383 of them became law.
