Answer:
The correct answer is- C. double or single-stranded DNA or double or single-stranded RNA.
Explanation:
All the viruses are intracellular parasites which means they obtain their nutrition from their host. Viruses do not have cellular level of organization. They only have their nucleic acid which is surrounded by a protein coat called a capsid.
The nucleic acid in viruses can be of different types. It can be single or double-stranded DNA or single or double-stranded RNA. Their genome can be linear or circular. They inject their genetic material in their host and introduce it in the host genome. Therefore the correct answer is C.

Explanation:
Deoxyribosenucleic acid, commonly called DNA is the stored form of genetic material in living cells. It contains the information needed by an organism to survive. A segment of the DNA that encodes the necessary information needed to produce a particular protein that determines a trait is called GENE.
The DNA consists of long polynucleotide chains, hence, due to Its length, it cannot git into the cell. The cell then devises a means by wrapping the long strands of DNA around certain proteins called HISTONES. This initially forms a NUCLEOSOME structure, then continuous wrapping around histones and condensation forms the visible CHROMOSOME structure.
Now, the CHROMOSOME contains the DNA molecule, which contains protein-coding segments called GENES. The information contained on the gene is used to produce a protein that is responsible for a particular TRAIT in the organism.
C
A Land mass is large geographical area that is surrounded by oceans. Therefore this can be synonymous to continents.
Explanation:
The crust is divided into tectonic plates that are dynamic because they move on top of the semi-plastic mantle. The movement of the tectonic plates is driven by the convection currents of the mantle that drag along the crust above. The tectonic plates collide at convergent boundaries where tectonic plates are consumed as one is subsided into the mantle. On the other hand, new crust is formed at divergent boundaries where two tectonic plates move away from each other and magma rises from the mantle and cools into new crust.
The convection currents occurs because the lower mantle is hotter and less dense compared to the cooler denser upper mantle. Therefore the upper mantle always tends to sink as the lower mantle rises. These convection currents are the same as in any other fluids that are disproportionately heated.
