Well, there are three different zones:
sunlight zone: the brightest; plants and algae can grow there, home to many ocean animals, and shallowest of zones
twilight zones: dimmer and colder water; plants an algae can not liver there; ocean animals that liver here live in darkness and many have big eyes
then there is the midnight zone: super cold and pitch black, food is scarce and few ocean animals liver there.
my best answer would be the sunlight zone...
The nucleus is an organelle found in eukaryotic cells. Inside its fully enclosed nuclear membrane, it contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
One long-term effect of water erosion is the erosion of soil that we use for agriculture. A way to prevent this is to protect the underlying soil with some sort of cover, especially in the case of erosion caused by rainfall.
