Answer: It demonstrated what Early Earth was like long ago, when organisms were basic. They tested what organisms were alive and what they were like.
The answer depends on the interpretation and understanding of the phylogenetic trees. The image shows the rooted phylogenetic tree consisting of the various kinds of organisms. The rooting of the tree is done by looking at how closely two species are related to each other. The species within a larger branch or archae are more similar to each other than with the species of the eukarya branch. The distance between the different branches of the tree also indicate how different they are. Larger the distance, the less related they become.
Answer: The reason is because DNA polymerase which is the enzyme that catalyzes the synthesis of DNA has a 3'->5' exonuclease activity that double-checks each nucleotide after it is added.
Explanation: The 3'->5' exonuclease activity of DNA polymerase allows the enzyme to double-check and remove a newly added wrong nucleotide. It is highly specific for mismatched base pairs. When the DNA polymerase adds a wrong nucleotide to the growing strand, translocation of the enzyme to the position where the next nucleotide is to be added is halted, but the exonuclease activity of the DNA polymerase removes the incorrectly paired nucleotide so that replication can continue. The process of double-checking a newly added nucleotide and removal of any incorrectly paired nucleotide by the DNA polymerase is called proofreading.
Answer: poor soil
Explanation: dead plants, horse manure, and NPK are organic, whether they be organic organisms themselves, or created and considered organic molecules, soil, or dirt is inorganic.
