Answer:
In the Northern Hemisphere, ecosystems wake up in the spring, taking in carbon dioxide and exhaling oxygen as they sprout leaves — and a fleet of Earth-observing satellites tracks the spread of the newly green vegetation.
Meanwhile, in the oceans, microscopic plants drift through the sunlit surface waters and bloom into billions of carbon dioxide-absorbing organisms — and light-detecting instruments on satellites map the swirls of their color.
Satellites have measured the Arctic getting greener, as shrubs expand their range and thrive in warmer temperatures. Observations from space help determine agricultural production globally, and are used in famine early warning detection. As ocean waters warm, satellites have detected a shift in phytoplankton populations across the planet's five great ocean basins — the expansion of "biological deserts" where little life thrives. And as concentrations of carbon dioxide in the atmosphere continue to rise and warm the climate, NASA's global understanding of plant life will play a critical role in monitoring carbon as it moves through the Earth system.
Explanation:
Answer:
Evolution is the gradual change in the inherited traits of a population over several generations. natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass their genes

The situation that a new technology would be most likely to cause change in existing theory about cell is : D. The technology allows detection of a substance that could not be detected previously
Cell is incredibly small and we still hasn't 100% figured out their perfect mechanism yet. New technology might found the new substance that alter the cell's theory as a whole
hope this helps
