Answer:
Explanation:
Carbon dioxide from the atmosphere dissolves in the surface waters of the ocean. ... Photosynthesis by tiny marine plants (phytoplankton) in the sunlit surface waters turns the carbon into organic matter. Many organisms use carbon to make calcium carbonate, a building material of shells and skeletons

Answer:
In the course of evolution mammals are the animals which are evolved recently as compared to other groups such as fish, amphibians, or reptiles.
In addition, fur or hairs on body, mammary glands, middle ear bone, warm-blood, et cetera are the characteristics of mammals.
These characteristics were evolved during the course of evolution; they were not present in ancestral organisms.
However, tail, gill pouches, et cetera are characteristics of our ancestral groups. Thus, characters can be sometimes observed in mammals.
But mammals characteristics can not be observed in organisms which were evolved before mammals such as fishes, amphibians, reptiles, et cetera.
Answer:
Fe2+ atom has a larger size than Fe3+.
Explanation:
The electron transport chain is important for the production of the ATP molecule. The oxygen molecule acts as the final electron acceptor in the electron transport chain.
The size of the cation is always small as compared with the parental atoms. Two electrons are removed from Fe2+ and three electrons are removed from Fe3+. This removal of electron increases the attraction force between the electron of the outermost shell and the nucleus and decreases the repulsion force between the electrons and thus decreases in size.
Answer:
Predator-Prey Relationship
Explanation:
If the extinction of one of the species leads to an increase in the population of the other species, then the relationship must be a predator-prey relationship, because the now-extinct species was keeping the now-increasing population of the other species in check.
