The statement above is TRUE.
In evolution, there are different level of succession. Ecosystems usually start out as barren lands or barren rocks; over the course of time, different types of plants and animals will exist on the land and eventual died out and this will continue until the ecosystem has attained its full succession.<span />

Answer:
The correct answer is e. Golgi apparatus
Explanation:
Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.
The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.
Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.
Therefore the correct answer is e. Golgi apparatus.
Replication of RNA genome in RNA virus does not involve proofreading. Thus RNA viruses have higher rates of mutation. So the correct option is B.
<h3>What is meant by proofreading? </h3><h3> </h3>
There are a variety of mechanisms in the cell to prevent mutations. Thus, permanent changes in the DNA sequence are prevented.
During the process of synthesis of DNA, DNA polymerases can analyse any mistake made during the synthesis and fix it. The majority of mispaired bases can be fixed by this process. It is called proofreading.
This process is not present in RNA and RNA polymerases. Thus RNA viruses appear to have higher rates of mutation compared to DNA viruses.
Therefore the correct option is B.
