Answer:
VIRUSES ARE MADE UP OF ONLY ATOMS AND MOLECULES -----YES
THEY CONTAIN GENES IN THE FORM OF EITHER DNA OR RNA------YES
THEY HAVE NO METABOLIC ACTIVITY AND THEREFORE CANNOT MAINTAIN A STEADY INTERNAL STATE ------YES
WHEN A VIRUS INFECTS CELLS, IT FORCES THE CELL TO MAKE MORE COPIES OF THE VIRUS------YES
THE GENES FOUND IN POPULATIONS OF VIRUSES CHANGE OVER TIME ALLOWING VIRUSES TO ACQUIRE NEW CHARACTERISTICS AND FEATURES-------YES
Explanation:
Viruses are minute micro-organisms made up of genetic material either DNA or RNA molecule and are surrounded by a protective coat called capsule made up of proteins. Viruses are very small that and cannot survive or live outside an host, who they infests. Viruses cannot maintain a steady internal environment and their reproduction is in close proximity with the host cells. They use the reproductive pathways of the host cell to allow for their own reproduction. They do not possess the protein synthetic enzymes and machinery to encode, transcribe or translate for a protein molecule and hence forces the host cells to make more copies of the virus. Viruses upon replicating in the host cells, leave the host cell either through budding or lysis that is bursting out of the cell. They kills the host cell and then leave to enter a new cell and multiply. Viruses are also known to evolve over time in a population in which new features of the virus can exits. For example when two viruses infect a cell, they can swap genes and and other genetic materials through recombination to form a new virus a situation in which is the cause for drug resistance in HIV.
