Stingrays. Stingrays are a family of cartilaginous fish containing nine genera and about 70 species. They can be found in all tropical and sub-tropical seas, and there is also a freshwater-only sub-family-the river rays. A flattened body shape and disc-shaped pectoral fins help stingrays live and hide in sand and mud underwater. The famous barbed stinger on the tail is only used in self-defence, often when they are stepped on in shallow waters.
Split and merge into it. Answer by Freezinweasle. Confidence votes 7.9K. A multimeter is used for measuring electricity and because it has many different functions, it has been named a multimeter. They generally measure AC and DC voltage, amps, and resistance (ohms).
A calorimeter is an object used for calorimetry, or the process of measuring the heat of chemical reactions or physical changes as well as heat capacity. Differential scanning calorimeters, isothermal microcalorimeters, titration calorimeters and accelerated rate calorimeters are among the most common types.he measurement of heat using a simple calorimeter, like the coffee cup calorimeter, is an example of constant-pressure calorimetry, since the pressure (atmospheric pressure) remains constant during the process. Constant-pressure calorimetry is used in determining the changes in enthalpy occurring in solution.
