uracil
Explanation:
because the rest are part of the DNA strand
Answer: The answer is b.
Explanation: The flowers are one of the most differentiating features of angiosperms. They are the reproductive structures of angiosperms. The flower has a thalamus that is a short axis and four whorls of sporophylls arranged on the thalamus. The four whorls of floral leaves include calyx, corolla, androecium and gymnocium.
Answer:
requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.
Explanation:
The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.
