They may also appear on other parts of the body. Warts have a rough texture and are caused by viruses, particularly one of several kinds of HPV (human papillomavirus). The virus causes keratin, which is a hard protein on the top layer of the skin, to grow too fast. Warts are not the same as moles.
The tropical rainforest is a hot, moist biome found near Earth's equator. The world's largest tropical rainforests are in South America, Africa, and Southeast Asia. Tropical rainforests receive from 60 to 160 inches of precipitation that is fairly evenly distributed throughout the year. The combination of constant warmth and abundant moisture makes the tropical rainforest a suitable environment for many plants and animals. Tropical rainforests contain the greatest biodiversity in the world. Over 15 million species of plants and animals live within this biome.
The tropical rainforest biome is an ecosystem that covers about 7% of the Earthâs surface. They are found all over the world but the majority of the tropical rainforest lies in South America in Brazil.The weather in the tropical rainforest is rainy yet pleasant all year round, day or night.ainforests are extremely important because the water they produce is evaporated and then used as rain in other areas. The average temperature of the tropical rainforest remains between 70 and 85Â° F. The tropical rainforest is very rainy as its name implies. The rainfall can reach up to 400 inches in one year.
