has a defined boundary - viruses are made up simply of genetic material surrounded by a<u> protein capsid </u>and sometimes a lipid membrane
Characteristics of Life Absent in Viruses:
made up of one or more cells - one of the main arguments for why viruses are not living is that they are <u>not cellular</u>
uses energy - this is a tricky one. They don't use or produce their own energy. However, in order to reproduce they do hijack the host cells and <u>steal energy</u> from them in order to reproduce
exhibits growth and development - although viruses do <u>reproduce</u>, the individual viral particles do not exhibit growth or development
possess internal organisation - other than the fact they ahve genetic material, the inside of a virus does not contain internal organization like a cytosol, instead conssiting of the bare minimum amount of proteins to survive
eliminates waste - since they do not have their own metabolism, they have no waste to eliminate
Lithium fluoride is a solid at room temperature because it is a salt that is held together by ionic bonds. Lithium. fluoride has a giant ionic structure.
