Both kelps and coral reefs are composed of algae that grow in the shallow parts of the ocean in warm and sunny waters. However, kelp forest grows in nutrient-rich waters while corals can develop in low nutrient waters.
Kelp forests are therefore common where warm and cold current meet in an up-welling. Coral reefs are borne of a symbiotic relationship between coral polyps and algae. The coral forms a rigid carbon skeleton of calcium carbonate while kelps are long flexible algae plants.
Answer:
D. none of the above
Explanation:
The only things that can live without oxygen are related to being microscopic like bacteria.
Answer:
The correct answer is: semi-conservative.
Explanation:
DNA replication is an important process in which the DNA is duplicated before cell division so each daughter cell can have a copy of genetic material.
DNA replication is <u>semi-conservative because one strand of DNA is new and the other one is the old strand</u>. To replicate itself, the DNA double helix is opened, and then each strand serves as a model for the new strands.
DNA replication is <u>not a one-step process</u>, as it takes several complicated steps in which <u>lots on enzymes participate</u> (like DNA polymerase and DNA helicase).
DNA replication is <u>also carried by prokaryotic cells</u>, though it's a much simpler process.
Sun provides energy to plants, which use it to make food from soil nutrients, which is eaten by animal, which is eaten by another animal, that produces waste and die, that decomposes and adds nutrients to the soil, which plants use with sunlight to make food from soil
