One is drift netting. These nets are indiscriminate and also
catch, injure and kill fishes that are not intended to be caught. This, therefore, greatly affects the marine ecosystem.
Second is over-fishing. This reduces the fish population to a
point where they are unable to regenerate and hence predisposes/ condemning them
to extinction
Third is the destruction of marine ecosystem, deliberately,
to clear an obstacle or pave the way for fishing lines. This damages the habits
hence affecting the ecosystem from primary producers and up the food chain.
Since, for example, carbon is organic matter, it has chemical reactions and burns when having contact with oxygen (creating carbon dioxide). Similarly, many organic matter burns when having a reaction.
In a typical lytic cycle, complete viral body doesn't enter the host cell rather it injects the DNA after the attachement. In case of SARS-CoV-2, the virla body is engulfed by the host cell.
In a lytic cycle, host cell's DNA is degraded and the viral DNA take over the machinery of the host to replicate. However, in case of SARS-CoV-2, host DNA is not degraded (at least unknown till today), then the released RNA remains in the host cytoplasm, and a specific section of infecting RNA is translated to make RNA-dependent RNA polymerase.
In a lytic cycle, newly formed copies ultimately break the cell wall and the viruses are released outside. In SARS-CoV-2, however, the release of virus does not require cell lysis. It is an enveloped virus.
<em>Similarities</em>
Just like lytic cycle, SARS-CoV-2 also finds a receptor on the host cell (ACE2) and attaches for further action (attachment step).
Once viral RNA-dependent RNA polymerase is produced, it makes complete copies of the genomic RNA of the SARS-CoV-2. Then, these copies are packaged into new virions.
The RNA is then translated into viral proteins such as structural proteins, viral proteases, and RNA-dependent RNA polymerase. This process is completed by using the host ribosomes.
The newly prepared proteins are packaged in the virions.
