Penguins are primarily found in the southern hemisphere, with the majority of species inhabiting the cold waters of Antarctica. They are well adapted to the extreme conditions of this region, including the icy waters and harsh climate. Penguins have evolved to thrive in the southern hemisphere, where they can find abundant food sources such as fish and krill. Additionally, the southern hemisphere offers suitable nesting grounds for penguins to breed and raise their young. Therefore, the correct answer is the southern hemisphere.

Guano is the correct answer because it is a term used to describe bird droppings. It is commonly used to refer to the excrement of seabirds or bats, which is rich in nutrients and often used as a fertilizer. The other options, Hulet, Bird poo, BLuy, and Brasini, are not commonly used terms for bird droppings.

Seabirds are characterized by having forelimbs that are wings, a four-chambered heart, and laying internally fertilized eggs. These features are unique to seabirds and help them adapt to their marine environment. The wings allow them to fly and navigate over long distances, the four-chambered heart ensures efficient circulation of oxygenated blood, and laying internally fertilized eggs allows them to reproduce successfully in the water. These traits differentiate seabirds from other birds and enable them to thrive in their specific habitat.
