Answer: The correct statement is ' the Size of the Earth'.
Explanation:
Most Greek scholars soo many years agreed that the earth was shperical in shape but never knew the size of the Earth.
Eratosthenes was a man of many talents, he was a geographer, a mathematician, an astronomer and a historian. With the expanse of knowledge he had, he compared the position of the sun and the shadows cast at noon on the summer solstice in two different cities. With reasonable accuracy, he was able to determine the shperical size of the earth. He computed this by using simple geometry and trigonometry and by recognizing Earth as a sphere in space.
Answer:
From food
Explanation:
Food energy is a chemical energy used by humans through the process of cellular respiration. Food contain macromolecules such as lipids, proteins, carbohydrates, water, vitamins, and minerals that are necessary for the human metabolism and they are broken down and used by the series of metabolic steps (glycolysis, Krebs cycle, electront transport chain and oxidative phosphorilation). Digested macromolecules should be used either as a source of energy or as building blocks for the cell.
At the end of catabolic processes within an organism food energy is transformed into energy usable by the cell-ATP.
Yes it is possible to determine the possible sequence of the second strand, as knowing that the strands run in anti parallel manner, the orientation of the deoxyribose sugar and the phosphate groups would be in the opposite direction as compared to the first strand, which is told based on the carbon on the phosphate and the sugar. Also since we know the base pairing rules of DNA, we can determine the nucleotide sequence of nitrogenous bases for the second strand.
