Which of these statements best explains why Copernicus and Kepler had different views about the solar system?
O They came from different cultures.
O They liked to disagree professionally.
O They had different goals and interests.
O They misinterpreted scientific facts and data.
The best statement that explains why Copernicus and Kepler had different views about the solar system is that they had different goals and interests, which is the third option, as Copernicus and Kepler had different perspectives on the solar system.
Copernicus, a Polish astronomer, was interested in the simplicity and elegance of the universe and sought to find a more accurate model of the solar system. He proposed that the sun, not the earth, was at the center of the solar system, which was a revolutionary idea at the time. On the other hand, Kepler, a German astronomer, was more focused on the mathematical and physical aspects of the solar system and used his observations of the planets to develop the laws of planetary motion.

many marine organisms depend on upwelling to bring nutrients to surface. how might El Nino affect a fisherman's way of life
The upwelling of seawater refers to the rising up of the deeper and cold water towards the surface of the sea. This cold water is comprised of the valuable and essential nutrients and as they move upward, it provides these nutrients to the marine organisms.
What is El Nino?El Nino is usually defined as the large-scale changes in the climate that occurs due to the interaction between the ocean and the atmosphere. It leads to the episodic rise in the temperature of the sea surface, which typically occurs in the central and the eastern part of the central Equatorial Pacific.
The occurrence of El Nino leads to the reduction of the upwelling of deep-sea cold water. During the time of this harsh climate, the fishes die or they sometimes migrate into some other places where they can obtain their food. Due to this, the fisherman cannot go fishing.
Thus, the occurrence of El Nino directly affects a fisherman's life.
