This hypothesis states that viruses originated from more complex cells<br> Select one:
-Dominant- [34]

Answer:

The hypothesis that states that viruses originated from more complex cells is called the regressive hypothesis.

Explanation:

The regressive hypothesis -also called <u>degenerative hypothesis</u>- raises the possibility that viruses originally were cells that behaved as symbionts or parasites of other cells, and this condition of dependence could have originated the disappearance of genes, becoming structures formed by nucleic acid inside a viral capsid (virus).

Some evidence gathered to support this theory suggests that some bacteria, such as rickettsia, need to parasitize a cell in order to replicate, just as viruses do.

Mitosis, the process of cell division, is most important for an organism's what?
iris [78.8K]
<span>Cell division serves as a means of reproduction in unicellular organisms through binary fission. In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. For growth to occur in living organisms, the number of cells have to increase through cell division until it reaches its maximum size. 

The human body also repairs injuries by means of cell division. When skin is cut, the skin cells on either side of the cut divide to make new cells that heal the wound.</span>

Beetroot cells contain a family of dark red pigments called betalains. The selectively permeable nature of the beetroot cells ke
finlep [7]

Answer:

B. When beetroot cells are placed in a solution with cellulase, the solution remains clear.

Explanation:

Cell membrane are not destroyed or damaged as cellulase digests cellulose, rather it damages the structure of the cell wall.

In conclusion, even though the Beetroot cell wall has been damaged, the lack of change in the color of the solution suggests that the betalain is not leaking out thereby refuting the claim that the alternative hypothesis that selective permeability is a consequence of the cell wall.
