Answer:
The two enantiomers of dopa have very different shapes, even if they have the same number of atoms of each element involved and have the same ones connected to one another. The great difference in activity shows that the key thing in determining biological activity is shape, not merely the number or arrangement of atoms.

Hurricane Floyd was a very powerful Cape Verde hurricane which struck the east coast of the United States. It was the sixth named storm, fourth hurricane, and third major hurricane in the 1999 Atlantic hurricane season. Floyd triggered the fourth largest evacuation in US history (behind Hurricane Irma, Hurricane Gustav, and Hurricane Rita) when 2.6 million coastal residents of five states were ordered from their homes as it approached. The hurricane formed off the coast of Africa and lasted from September 7 to September 19, peaking in strength as a very strong Category 4 hurricane—just 2 mph short of the highest possible rating on the Saffir–Simpson Hurricane Scale. It was among the largest Atlantic hurricanes of its strength ever recorded.

Floyd was once forecast to strike Florida, but turned away. Instead, Floyd struck The Bahamas at peak strength, causing heavy damage. It then paralleled the East Coast of the United States, causing massive evacuations and costly preparations from Florida through the Mid-Atlantic states. The storm weakened significantly, however, before striking the Cape Fear region, North Carolina as a very strong Category 2 hurricane, and caused further damage as it traveled up the Mid-Atlantic region and into New England.
The hurricane produced torrential rainfall in Eastern North Carolina, adding more rain to an area already hit by Hurricane Dennis just weeks earlier. The rains caused widespread flooding over a period of several weeks; nearly every river basin in the eastern part of the state exceeded 500-year flood levels. In total, Floyd was responsible for 57 fatalities and $6.5 billion (1999 USD) in damage. Due to the destruction, the World Meteorological Organization retiredthe name Floyd.
Answer:
Grass -Grasshopper - Frog - Phyton - Eagle
Answer:
The correct answer are option A. "A microbiologist with the U.S. Geological Survey grew crescent-shaped fungal spores in a lab on refrigerated plates" and option C. "A specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose".
Explanation:
Doctor Blehert and Doctor Behr are two scientists that are studying the relationship between fungal disease and the development of the bat white nose syndrome. In order to prove that bat white nose syndrome is caused by a fungal disease Blehert and Behr first took samples in the field and later analyzed the samples in the laboratory. First, a specialist with the New York State Health Department detected crescent-shaped fungal spores when examining a sample swabbed directly from a living bat with a white nose. Later, the samples taken from the shaped fungal spores were grew in the laboratory on refrigerated plates by a microbiologist with the U.S. Geological Survey. After analyzing the samples, the scientists conclude that the bat white nose syndrome is caused by a fungal disease.
Fertile land is lost, and there is increased pollution and sedimentation in rivers and other aquatic areas.
