How did Leland Melvin change the face of science

Leland is the only person drafted into the National Football League to have flown in space. The Pro Football Hall of Fame honored his athletic and academic accomplishments by placing his Detroit Lions jersey under glass in Canton, Ohio. Through these professional experiences working on high stakes teams he developed a deep and nuanced understanding of effective team dynamics.

Leland has a Bachelor of Science degree in chemistry and a Master’s degree in materials science engineering. He worked at NASA Langley Research Center in the area of nondestructive testing creating optical fiber sensors for measuring damage in aerospace vehicles, resulting in publications in numerous scientific journals. After hanging up his space boots he was appointed head of NASA Education and served as the co-chair on the White House’s Federal Coordination in Science, Technology, Engineering, and Mathematics (S.T.E.M.) Education Task Force developing the nation’s 5-year STEM education plan. Leland was the United States representative and chair of the International Space Education Board (ISEB), a global collaboration on learning about space. He uses his life story as an athlete, astronaut, scientist, engineer, photographer, and musician to help inspire the next generation of explorers to pursue Science, Technology, Engineering, Art, and Mathematics (S.T.E.A.M.) careers.

Explanation:

the answer as multiple choice is c

africa, the second-largest continent, is bounded by the mediterranean sea, the red sea, the indian ocean, and the atlantic ocean. it is divided in half almost equally by the equator. the continent includes the islands of cape verde, madagascar, mauritius, seychelles, and comoros.

africa’s physical geography, environment and resources, and human geography can be considered separately.

the origin of the name “africa” is greatly disputed by scholars. most believe it stems from words used by the phoenicians, greeks, and romans. important words include the egyptian word afru-ika, meaning “motherland”; the greek word aphrike, meaning “without cold”; and the latin word aprica, meaning “sunny.”

today, africa is home to more countries than any other continent in the world. these countries are: morocco, western sahara (morocco), algeria, tunisia, libya, egypt, sudan, chad, niger, mali, mauritania, senegal, the gambia, guinea-bissau, guinea, sierra leone, liberia, côte d’ivoire, ghana, burkina faso, togo, benin, nigeria, cameroon, central africa republic, equatorial guinea, gabon, congo, democratic republic of the congo, angola, namibia, botswana, south africa, lesotho, swaziland, mozambique, zimbabwe, zambia, malawi, tanzania, rwanda, burundi, uganda, kenya, somalia, ethiopia, djibouti, eritrea and the island countries of cape verde, madagascar, mauritius, seychelles, and comoros.
