   The bulbourethral glands (also known as the cowper's glands) are  male sexual glands. They are located below the prostate and  discharge a component of the seminal fluid into the urethra. During  sexual intercourse each gland produces a secretion known as  pre-ejaculate.he word sweetbread is first attested in the 16th century, but the etymology of the name is unclear.[4] Sweet is perhaps used since the thymus is sweet and rich-tasting, as opposed to savory-tasting muscle flesh.[5] Bread may come from brede 'roasted meat'[6] or from the Old English brÇ£d ('flesh' or 'meat').
Global warming caused by greenhouse gases is a major threat to the permafrost in parts of the tundra region. This process causes the emission of more carbon dioxide and methane to be released from the melting arctic surfaces into the atmosphere, accelerating the rate of global warming.
The areas Tundras are typically found in areas that contain a lot of methane. The methane lies under the permafrost of the soil. When the permafrost melts, large amounts of permafrost will be let into the atmosphere and heat up the earth.
