A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.
Homeostasis is a state of stable internal environment that is mainteined by an organism. Maintaining the stable temperature (thermoregulation) is one of the examples of maintening the homeostasis and it is achieved by the skin in humans. The skin control of the temperature:
1.sweating- the sweat glands of the dermis secrete sweat that lower the temperature via evaporation,
2. skin circulation-vasoconstriction and vasodilation of the blood vessels inside the skin regulates the temperature. For example, when the body temperature is high, the blood vessels dilate, allowing heat to be released through the surface of the skin,
3. insulation by the subcutaneous layer of the skin which is made of fat cells and fibrous tissue
4.piloerection.
There are 4 ways of the heat loss from the skin:
1.radiation
2.conduction
3.convection
4.evaporation

Answer:
DNA.
Explanation:
Type II restriction endonucleases always cleave at or near their recognition sites. They produce small, well-defined fragments of DNA that help to characterize genes and genomes and that produce recombinant DNAs.
