Brazil's Atlantic Forest is considered one such hotspot, containing roughly 20,000 plant species, 1,350 vertebrates, and millions of insects, about half of which occur nowhere else.[citation needed] The island of Madagascar and India are also particularly notable. Colombia is characterized by high biodiversity, with the highest rate of species by area unit worldwide and it has the largest number of endemics (species that are not found naturally anywhere else) of any country. About 10% of the species of the Earth can be found in Colombia, including over 1,900 species of bird, more than in Europe and North America combined, Colombia has 10% of the world's mammals species, 14% of the amphibian species, and 18% of the bird species of the world. Madagascar dry deciduous forests and lowland rainforests possess a high ratio of endemism.[citation needed] Since the island separated from mainland Africa 66 million years ago, many species and ecosystems have evolved independently.[citation needed] Indonesia's 17,000 islands cover 735,355 square miles (1,904,560 km2) and contain 10% of the world's flowering plants, 12% of mammals, and 17% of reptiles, amphibians and birdsalong with nearly 240 million people. Many regions of high biodiversity and/or endemism arise from specialized habitats which require unusual adaptations, for example, alpine environments in high mountains, or Northern European peat bogs.[citation needed]
Which country has the highest rate of species by area unit worldwide?

Heartwood is often visually distinct from the living sapwood, and can be distinguished in a cross-section where the boundary will tend to follow the growth rings. For example, it is sometimes much darker. However, other processes such as decay or insect invasion can also discolor wood, even in woody plants that do not form heartwood, which may lead to confusion.
What kind of plants never form heartwood?
A: woody

On August 18, 1970, the NAACP filed suit against Michigan state officials, including Governor William Milliken, charging de facto public school segregation. The NAACP argued that although schools were not legally segregated, the city of Detroit and its surrounding counties had enacted policies to maintain racial segregation in public schools. The NAACP also suggested a direct relationship between unfair housing practices and educational segregation, which followed segregated neighborhoods. The District Court held all levels of government accountable for the segregation in its ruling. The Sixth Circuit Court affirmed some of the decision, holding that it was the state's responsibility to integrate across the segregated metropolitan area. The U.S. Supreme Court took up the case February 27, 1974. The subsequent Milliken v. Bradley decision had wide national influence. In a narrow decision, the Court found that schools were a subject of local control and that suburbs could not be forced to solve problems in the city's school district.
Who was Governor of Michigan in 1970?
A:
William Milliken
