Answer:
A
Explanation:
Usually a virus is mainly made up of genetic material (DNA or RNA) inside a capsid/envelope. It has no organelles like a ‘true’ cell. Because it cannot reproduce on its own, scientists struggle to categorize it as a living thing since reproduction is a property of living things. The virus reproduces by hijacking the cellular mechanisms of the host cells to replicate itself. It does so by integrating itself in the genome of the host so that its DNA is also replicated, along with that of the host, by the host cell DNA polymerases and its proteins produced by the ribosomes of the host.
The answer is because a part of the organism could die and the organism could continue to live.
In the very changing environment, such was when multicellular organisms evolved, the organisms that could adapt to that environment, survived. If in some moment multicellular organism emerged and its multicellularity helped him to survive, that is the reason this characteristic remained. On of the explanation is that multicellularity allows the organism to continue to live even if <span>a part of the organism dies.</span>
Answer:
Body tissues grow by increasing the number of cells that make them up. Cells in many tissues in the body divide and grow very quickly between conception and adulthood. This process is called cell division. One cell doubles by dividing into two
