The other techniques such as quantitative technique which provide information about the numerical value of data.
Qualitative technique is used in research would collect data on growth of the bacterial sample on the solid growth of the sample. It is used to assess whether the bacteria in the data is living or dead. It reveals the wealth of the qualitative information of data. The observation of microorganism in microscope get information whether the organism is in propelled motion or its dead.
Surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity
The copepods would most likely decrease because the copepods eat the shrimp
