Fossil fuels release carbon dioxide, nitrogen dioxide, sulfur dioxide, carbon monoxide etc. when burnt that can have severe consequences on the habitats. They are non-renewable sources of energy as they are derived from pre-historic fossils and won’t be available once they are fully used. Their sources are limited and they are depleting at a faster rate.
Answer:
The correct answer is the first option which represent the structure of a nucleotide.
Explanation:
DNA double is formed by the attachment of deoxy ribonucleotides joined to one another by phosphodiester bond during the course of DNA replication.
DNA is a nucleic acid.As a result it is a macromolecule.The macromolecular structure of DNA consist of numerous deoxy ribonucleotides.
The statement about cellular respiration that is not true is this: KREB'S CYCLE ACTIVITY IS DEPENDENT SOLELY ON AVAILABILITY OF SUBSTRATES; OTHERWISE IT IS UNREGULATED.
Kreb's cycle refers to the series of biochemical reactions through which humans generate energy in the presence of oxygen via the oxidation of acetyl COA.
The major factors that regulate the Krebs cycle is the concentration of ATP and NADH. The cycle is strictly controlled based on the level of energy available in the cells. The key regulatory enzymes for the cycle are isocitrate dehyrogenase and alpha ketoglutarate deydrogenase.
