I would say that the fishes exhibited the greatest diversity (though the brachiopods also had considerable diversity) and mostly were of the ostracoderms (with a platey or shell-like skin and no jawbone) which exhibited many varieties and also the placoderm which had gills, a jawbone and fins so was developing characteristics of modern fish.

Answer:
D) In DNA, adenine, thymine, guanine, and cytosine join together and carry all of the genetic information. RNA is made from adenine, uracil, cytosine, and guanine and is used to make proteins.
Answer:
Answer is Calvin cycle.
Explanation:
Calvin cycle is very important to plants because it helps in the conversion of organic products for the usefulness of plants. This is because the carbon dioxide and water are converted to glucose, which is useful to plants.
Calvin cycle can be explained as the production of glucose through the use of chemical energy from NADPH and ATP, produced in light reactions, to convert the atmospheric carbon dioxide to RuBP, which is a five-carbon molecule.
Answer:
The correct option is A. They provide the energy required to build high-energy sugars.
Explanation:
Calvin cycle can be described as the series of dark reactions of the process of photosynthesis.
During the Calvin cycle, carbon dioxide is reduced to glucose. The molecules of NADPH and ATP play an active role in this reaction to occur. The molecules of ATP serve as a source of energy. Whereas, the molecules of NADPH serve as a reducing agent. Electrons are added by NADPH so that carbon dioxide gets converted into glucose.
