DNA was isolated from water samples taken from six different sites. This gel was made to determine where silver carp are found.
1 2 3 4 5 6 7 8
1. North Shore Site 1
2. North Shore Site 2
3. Chicago Site 1
4. Chicago Site 2
5. Calumet Site 1
6. Calumet Site 2
7. Negative Control
8. Positive Control
The results of the eDNA analysis for silver carp,
How do scientists know silver carp are at North Shore site 1 (lane 1)?
A. One of the bands in lane 1 matches a band in lane 2.
B. One of the bands in lane 1 matches a band in the negative control.
C. One of the bands in lane 1 matches a band in the positive control.
D. None of the bands in lane 1 matches a band in either control.

the product of the pressure and volume is also constant

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
