Answer:
The abiotic and biotic factors that control viral activity at sea are: Sunlight, presence of bacteria, presence of eukaryotic microorganisms and presence of suspended particles.
Step-by-step explanation:
As you already know, viruses are obligatory acellular particles and tiny parasites. They can be present in different environments, including the sea, where they can establish viral activity in different environments.
Viruses are composed of a nucleic acid molecule and a protein coat. This nucleic acid is highly changeable, being able to modify the viral activity of several forms.
Under the sea the main factors that can cause these mutations that modify viral activity are:
- Solar radiation, through UV waves. These waves can destabilize the nucleic acid causing a mutation.
- These viruses can "swallow" particles suspended in the aquatic environment. These particles can become involved with the nucleic acid, modifying it.
- The presence of bacteria capable of parasitizing a virus through its enzymes can also cause changes in viral activity. Just like eukaryotic microorganisms.
