Hey There! I'm going to say the answer is D "<span>There are no limiting factors to control population growth." Thats just because the certain species will just keep producing and producing which means their is no limit to how many of its kind there can be!</span>
Answer:
Cambrian explosion
Explanation:
Cambrian explosion is a geological event that happened during the Cambrian age (541 million years ago). In this period, most of the animal phyla (including marine) appeared and their geological record is preserved in the form of fossils. The period lasted for 13-25 million years. Before this period, the organisms were very simple. They were mostly unicellular in nature and were living in the form of colonies.
The remaining three options are incorrect. They are tectonic events that reflect movement of continents in different geological times. None of them resulted in the diversification of (marine) animal phyla.
Answer:
DNA polymerase
Explanation:
The process in which DNA make its copies is called DNA replication.
It is true that DNA do not have any catalytic activity in the cells but there are several enzymes which participate in the process of DNA replication and performs different functions. DNA Polymerase is one of the key enzyme that participate in the process and catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA.
Arthur Kornberg in 1956 discovered DNA polymerase along with his colleague in Escherichia coli. DNA Polymerase catalyzes the addition of phosphodiester bonds with the help of formation of hydrogen bonds between the adjacent strands of DNA and build the backbone of DNA. Other functions of DNA polymerase involves synthesis of DNA from the RNA primers , helps in the elongation of leading strand, and DNA sequencing.
Hence, DNA polymerase is catalyzes the formation of phosphodiester bonds between adjacent nucleotides in the DNA.
