Which of the following statements best describes one role of water in living organisms? prevents transmission of disease between species send signals between nerve cells maintain a constant internal temperature forms a protective coating around cells

Water helps to maintain internal constant temperatures. Water acts as a temperature buffer. High temperatures affects chemical reactions in the body since it denatures enzymes which act at specific temperatures. When temperatures are high the rate of sweating increases, water on the surface of the skin evaporates thus cooling the body by a process called latent heat of vaporisation. 

When a virus infects a host cell, it uses the cell's machinery to make copies of its own genetic material in a process called replication. finally, during the process of self-assembly, that protein shell and the copies of the virus's genetic material are assembled into new viruses.
