What is important for many of the reactions that take place in the cells, as well as an ingredient that helps support an organism's body?
5
Genetic material enclosed in a protein shell however it is not a living thing.
6
True or False: virus particles do not grow once they have formed and they do not take in any energy

There are two types of single cell organisms that do not have nuclei, bacteria and
13
Which single celled organism can survive in the largest range of environments?
