Geologists have used the principle of superposition to determine that deeper layers of rock are usually older than shallower layers of rock.

What noticeable trend from this graph might be used to make a conclusion?

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.

Consider this microscopic image of bacteria, which bacterial form is shown in the image?
