   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 land has very little nutrients for plants. The Tundra Biome is the biome which is most affected by human pollution. The sun is almost 24 hours in summer day, meaning that there are mostly no nights. In the winter, Tundra Biome has few hours of sunlight. The Tundra Biome is covered by a frozen layer of soil.
