   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.
There are two types of tundra-arctic tundra and alpine tundra. The arctic tundra is located within the Arctic Circle while the alpine tundra is the area high in the mountains above trees. The plants that grow in the tundra biome often grow in clusters to help protect themselves from the severe winter winds.here are very few trees that grow in the tundra biome. Under the snow and ice, there is a thick layer of soil that remains frozen which does not allow deep rooted plants such as trees to grow. The tundra biome has about 400 varieties of flowers but only 48 different animals.
