Answer:
The correct option is C. A virus contains RNA or DNA in a protein coat.
Explanation:
Viruses can be described as tiny particles which are able to incorporate their genetic material into a host. Many viruses can be destructive to the host cells.
The structure of a virus includes DNA or RNA which is enclosed in a structure known as an envelope or capsid. The envelope or capsid is made up of proteins. Some viruses also have a tail.
The capsid of a virus usually remains outside the host cell and it injects its viral genome into the host cell. The DNA or RNA o the virus then incorporates in the host cell.
The United Nations Conventions on the Law of the Sea (UNCLOS) stipulates that seabed area, which is not within the landmark of any particular country should be regarded as a common natural heritage. Consequently, any mineral found in such an area can be used by anyone.
However, because of the abundant presence of sea area, and the way national boundaries often conflict, coupled with the problem of illegal mining practices, such laws are difficult to enforce, and so these regulations are not standardized yet.
Some possible impacts of ilegal seabed mining are:
1. Destabilisation of oceanic systems.
2. It constitutes danger to the organisms living in the hydrothermal vents.
