Using your Trial 1 data from Procedure II (Data Table II) and Procedure III (Data Table III), and the known concentration of guanine (see Activity Form tab), calculate the concentration of the cytochrome c solution. Activity form: Concentration is a measure of the amount of a substance contained per unit volume. A commonly used unit for the amount of substance is the mole (mol). When used along with the metric unit for volume, concentration may be expressed in mole per liter (mol/L). Often, for the small concentrations associated with biological systems, millimole per liter (mmol/L) may be used to express concentrations. One millimole is 1/1000 of a mole.

The hematodinium parasite becomes less of a problem for the blue crab when the crab is very young. fishing is thriving in the region. the crab moves to less salty water. a significant percentage of the population is impacted.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
