Answer:
A. Early signs of life on earth
Explanation:
The Hadean, before the Archean, is the first geologic eon of Earth. It began with the formation of the Earth about 4600 million years ago and ended 4,000 million years ago. The planet had just formed and was still very hot due to high volcanism, a partially molten surface. Some geologists labels the period before the earliest-known rocks on Earth. At the end of it much cooler surface temperature and the formation of solid rock enabled to flaurish the life.
Generally, the graph line will begin as a straight line when the substrate concentration is low. At very low substrate concentrations, the rate is proportional to the substrate concentration. As substrate concentration increases, it affects the enzymatic reaction, so the rate will change and the line will change.
The answer is C. These structures are vacuoles and are found in plants cell (you can tell it’s a plant cell because of the outer cell wall in the picture). Vacuoles have a variety of other functions storage of waste products, maintain turgor pressure for plants support.
