A student collected data from an experiment on muscle fatigue. In order to interpret these data, the student should
ignore the data because they do not support their hypothesis
recalculate the data so that the numbers are easier to work with
share the data with a student who has none
organize the data into a table or graph
The current knowledge concerning cells is the result of the investigations and observations of many scientists. The work of these scientists forms a well-accepted body of knowledge about cells. This body of knowledge is an example of a

The diagram below shows how a coverslip should be lowered onto some single-celled organisms during the preparation of a wet mount.
Why is this a preferred procedure?
The coverslip will prevent the slide from breaking.
The organisms will be more evenly distributed.
The possibility of breaking the coverslip is reduced.
The possibility of trapping air bubbles is reduced.
