Answer:
The answer is "Nucleus" and "Center"
Explanation:
Organisms comprise of a large number of cells, however like every other living being, you begun life as a solitary cell. How could you create from a solitary cell into a living being with trillions of cells? The appropriate response is cell division. After cells develop to their greatest size, they partition into two new cells. These new cells are little from the outset, yet they develop rapidly and at last separation and produce all the more new cells. This cycle continues rehashing in a ceaseless cycle.
Cell division is the cycle wherein one cell, called the parent cell, partitions to frame two new cells, alluded to as girl cells. How this happens relies upon whether the cell is prokaryotic or eukaryotic.
Cell division is easier in prokaryotes than eukaryotes on the grounds that prokaryotic cells themselves are less complex. Prokaryotic cells have a solitary roundabout chromosome, no core, and few different organelles. Eukaryotic cells, interestingly, have various chromosomes contained inside a core and numerous different organelles. These cell parts must be copied and afterward isolated when the cell separates.

Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
- <u><em>Destruction of the habitat of life forms present on the sea floor</em></u><em>, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.
</em>
- <em><u>Extinction of marine species that inhabit the seabed</u></em><em>. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.</em>
Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.
