Answer:
Option A, hydrogenous sediments
Explanation:
Hydrogenous sediments are made up of minerals suspended in water that precipitates out in due course of time thereby forming minerals. These sediments are found in a very small amount and generally constitute 0.5 to 1 % of the total ocean sediments. While cosmogenous sediments are made up of space materials falling on earth, biogenous sediments are made up of living organism remains, lithogenous sediments are made up of land. All manganese, ferromanganese and phosphite nodules are hydrogenous
Hence, option A is correct
Explanation:
If they´re mutated it means that there was a modification in they´re genes, which makes them resistant to any actions that us humans took to prevent the previous generation of influenza viruses.
Answer:
Since there was a change in their genetic code to resist our treatments/ preventions, they pose a higher risk to us. Why? Because our treatments/preventions will be useless and the virus might cause some damage until our solutions to prevent/cure it are updated, that is, if we don´t have to re-invent any.
Tip:
You can think of the influenza virus as a software. The mutation can be an update that gets rid of a bug, which would be our preventions (vaccines).
