Answer:
Virus
Explanation:
A virus is an infectious particle which is composed of the genetic material enclosed in a protein structure called capsomere.
Since the virus does not fulfil the criterion of a living thing like it has its metabolism, reproduction, growth, movement and cellular structures therefore it is considered as a non-living thing.
Since the virus does not have reproductive machinery therefore they use the DNA replication machinery of host. They use the host's machinery by integrating their genome in the genome of the host and replicate their genome. Through this mechanism, they make copies of them.
Thus, the virus is the correct answer.
Continental Rifts occur when the Earth's plates either push into each other or pull away from each other , and can lead to the formation of a volcano . When this occur the Earth's crust is broken up into pieces called plates. The place where the edges of two plates meet is called a boundary

The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.
The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
