Answer:
D. seafloor spreading
Explanation:
If you explore two oceanic plates at a convergent boundary , you will observe seafloor spreading.
Answer:
1. coevolution
2. abiogenesis
3. Endosymbiont Theory
4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.
5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.
6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.
7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.
8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.

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.
