   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.
Animals of the Tundra. Due to the harsh conditions of the tundra biome, there are only certain animals that can survive in this environment. There are a few large species, such as musk oxen and caribou, that live in the tundra, but most animals are smaller in size.lthough such a land may sound unbelievable, there is one environment on Earth with such a description, and it is the tundra biome. This biome is very unique because of its harsh climate and limited vegetation and animal life. The tundra biome covers a large area of land in the region just south of the Arctic ice caps.
