   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.
PLANTS: You would think that plants would never live or survive in this biome, but the answer is quite a surprise. There is low diversity in organisms that live here, but many still flourish. Many lichens, mosses, and small shrubs flourish in the arctic tundra. The plants that live in the harsh permafrost soil usually adapt to the weather by being short and grouped together to resist winds and to be protected. The growing season in the tundra is short and lasts up to 60 days. Tundra plants get their energy from the sun through photosynthesis like all other plants, but have adapted to low temperatures and low light intensities. Compared to plants in other biomes they use a minimal amount of energy. ANIMALS: You may think that the tundra is too chilly for animals, but guess what - itâs not. There are actually animals that live in this harsh biome! You might find lemmings, caribou, and arctic hares in the tundra.
