This forms about 2-5% of the semen composition. Apart from these, the bulbourethral glands produce a clear secretion. This helps in mobility of the sperm cells in the vagina and cervix. The glandsâ secretion contribute less than 1% to the overall semen composition. The semen comprises of: 1  fructose. 2  ascorbic acid. 3  zinc. 4  cholesterol. 5  protein. 6  calcium.
So why do we do it? Because the government tells us to. Congress mandated that beginning in 2007 daylight saving time would start the second Sunday in March and end the first Sunday in November -- an extension of four weeks from the old daylight saving time. States could opt out; only Arizona and Hawaii have. Don't count on saving on energy bills with daylight saving time. Even though DST in the United States came about in the Energy Policy Act of 2005, the leading author on daylight savings time said it only cuts electrical use by 0.5 percent -- if that. A study in Indiana in 2008 showed little change in energy use when parts of the state went to daylight saving time.
Many countries change their clock twice a year to observe day light saving time. The date of Daylight Savings Time Starts and Ends may vary with year to year and also depends on location. In United States DST starts on the second Sunday of March at 02:00 AM. And it ends on the first Sunday of November at 03:00 AM by setting clocks back to 02:00 AM. DST 2015 will begin on 8th March 2015 and will end on 1st November.
