Scientists used major changes in life forms in the fossil record to form the geologic time scale true or false

The correct answer is;

True

Explanation:

Fossils are fundamental to the geologic time scale. ... Rocks formed through the Phanerozoic Eon may have fossils of complicated animals and plants such as dinosaurs, mammals, and trees. We study Earth's history by studying the record of past experiences that are stored in the rocks. The geologic time scale (GTS) is a system of chronological dating that describes geological strata (stratigraphy) to time. It is used by geologists, paleontologists, and other Earth scientists to explain the timing and connections of events that have occurred during Earth's history.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
