Answer:
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Oceanic crust is hydrothermally altered causing addition of quartz and sodium.
Answer:
C) Unrestricted whaling could lead to their extinction.
Explanation:
The whaling is a process of hunting and killing whales so as to get the meat, oil and whalebone so that they can be sell it out commercially. The trade of whale resources was firstly in France and Spain in 16th century but they have been spread worldwide. However, the conservation groups worldwide are pushing the restriction on whaling as unrestricted whaling can lead to complete extinction of the whale species from the Earth.
I’m pretty sure it is Synchondrosis
Answer:
RNA-dependent RNA polymerase.
Explanation:
DNA polymerase I is present in E.coli that are responsible for the prokaryotic DNA replication. The DNA polymerase I was discovered by Arthur Kornberg. This enzyme is coded by the gene polA.
DNA polymerase I has the activites of DNA-dependent RNA polymerase, DNA-dependent DNA polymerase and RNA-dependent DNA polymerase. The RNA-dependent RNA polymerase is generally present in the reverse transcriptase in case of viruses only. RNA-dependent RNA polymerase catalytic site is not present in DNA polymerase I.
Thus, the correct answer is option (1).
