A scientist grew Bacteria in a system that allowed for the addition of fresh nutrients and the removal of waste products. Bacteriophage (virus) were added
at the time shown and the following population changes were observed. a)
Describe and explain two changes observed in the number of bacteria after the
virus is added. b) Describe how the genome of a retrovirus like HIV (Human
Immunodeficiency Virus) becomes incorporated into the genome of the host cell

b

Explain why viruses are not considered to be living.

viruses are not considered to be living because they lack cells and cannot reproduce on their own. although viruses contain DNA, they do not have a cell membrane, cytoplasm, ribosomes, or other organelles. they also need to use the cells of living organisms in order to replicate.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
