The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.
Hope this helps!
Hummm... i think the answer is.. D....
Hope this is correct!
Bacteria. As I remember I’m sure it’s bacteria
Answer:
The correct option is E.
Explanation:
Lymphocytes are known as white blood cells, and also main type of immune cells. They are synthesized in the bone marrow, and present in the blood, and lymph tissues.
1) The immune cells work together to protect the body against foreign molecules such as virus, and bacteria.
2) They contain MHC antigens for recognizing self.
3) They contain membrane receptors that recognize foreign antigens.
4) They are helping to develop into clones of B and T cells with extreme variations of specificity.
