ions because it’s still the same element, however the charge has changed
Answer:
The validation of seafloor spreading in the 1950s and 60s
Explanation:
The theory of seafloor spreading was supported by numerous evidence including thermal probes that showed that heat flow over the mid-ocean ridges measured up to four times those measured in general bottom sediments, which are taken as due to the presence of molten Earth material close to the ridge crest
The ridge crest also show signs unusually seismic wave velocities that are considered to be due to microfracturing and thermal expansion from upwelling magma
Answer:
Oxidation number is the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.

Answer:
B. Their productive organisms play a major role in nutrient recycling.
Explanation:
Coral reefs contain photosynthetic algae that help coral reefs in processing nutrients and contribute in the nutrient cycle.
The process of photosynthesis in corals leads to carbon fixing in which corals transform, carbon dioxide, into organic carbon. carbon fixing property allows corals to become primary producers.
Dissolve organic matter produced by corals is consumed by several organisms such as crabs, worms, fish, and snails.
Hence, coral reefs maintain the flow of energy and nutrient cycle in the biosphere and the correct option is B.
