Answer: The environment changed suddenly from a shallow ocean setting to a river system.
Explanation: Changes seen in rock layers represent changes in Earth's local history. The rock layer stack overall shows a shallow ocean setting. But the youngest layer at the top was deposited by a river. This shows the geologist that the local environment changed suddenly from an ocean setting to a river system.
The endosymbiotic hypothesis explains that how eukaryotic cells might have evolved chloroplasts and mitochondria within their cells.
The endosymbiotic hypothesis states that the eukaryotes have developed via a procedure whereby distinct kinds of free-living prokaryotes became assimilated within the bigger prokaryotic cells and ultimately evolved into chloroplasts, mitochondria, and various other organelles.
Efficiency is the measure of how much work or energy is conserved in a process. In many processes, work or energy is lost, for example as waste heat or vibration. The efficiency is the energy output, divided by the energy input, and expressed as a percentage.
Efficiency is the energy output, divided by the energy input, and expressed as a percentage.
Efficiency = (1350/1500)×100
= 90%
