Which of the following does NOT increase water density?
Contact [7]

Answer:

Increase in biomass

Explanation:

All the other choices have attributes that influence the density property of water except biomass. Biomass is organic material/ matter that is mainly carbon-based – mainly derived from plants and animals. This has no relationship to water density even when the biomass is in the water because it's only gets suspended like sediment and does not get dissolved in the water.

Sketches and the photos taken at the crime scene are also the part of the evidence they collect. Since here the bloodstains found by the Forensic investigators are less than 1mm diameter, they can deduce the weapon used for crime would be shotgun as it has a narrow barrel.</span>
