The answer is c in a variety of biomes
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.

Answer:
Option-3 and 4
Explanation:
In the given question, the table of the different nitrogen bases of a different organism has been provided in which the number of bases has been mentioned.
In the table, the amount of thymine is almost similar or equal to the adenine while the number of guanines almost equal to the cytosine for a particular species. This data follows the Chargaff postulates which state that adenine bind thymine and cytosine bind guanine therefore the number of complementary bases will be equal.
Thus, Option-3 and 4 are correct.
