Explanation:
Plants have been using light in this primal way for a large chunk of Earth's existence. But just how did they gain the ability to photosynthesize? The short answer is they stole it, about a billion and a half years ago, when single-celled organisms called protists engulfed photosynthesizing bacteria.
Answer:
Yes, it is estimated that there are about one trillion microbes species on earth, and we have not been able to isolate 99.99% of them, so, the knowledge is very limited. There is an study approach called METAGENOMICS. In Greek, meta means “transcendent.” It is a research field that allows to study comunities from their total DNA. It is, you can extract and sequence DNA from a sample, and find out about the composition of the population in there, even the interactions between them, with no need of pure culture.

DNA is deoxyribonucleic acid while RNA is ribonucleic acid !
DNA has base pair of adenine guanine thymine and cytosine.....while RNA has adenine guanine cytosine and uracil !
DNA is always double helix while RNA is mainly single helix !
DNA contains genetic info for 99℅ of organism while RNA is being catalytic and unstable than DNA is only present as genetic information holder in 1℅ !
DNA does not involve in protein synthesis directly but RNA has to !
for more difference, comment !
Answer:
According to the current fossil record, scientists believe that the life on earth began about 3.5 billion years ago.
