Answer: 5
Explanation The energy released (14135 KJ) is equivalent to the energy released from the oxidation of glucose (C6H12O6), which is typically around 2820 KJ/mol. To find the number of moles of glucose consumed , you can divide the energy released (14135 KJ) by the energy released per mole of glucose (2820 KJ/mol): 14135 KJ ÷ 2820 KJ/mol = 5 mol
مائٹوسس کا مرحلہ جس میں کرومیٹڈز قطبوں تک پہنچ جاتے ہیں اور ان کی حرکت بند ہو جاتی ہے؟
Answer: Telophase
Explanation In Telophase, the chromatids (now called chromosomes) have reached the poles of the cell and their movement ceases. The nuclear envelope begins to reform around each set of chromosomes, and the cytoskeleton reorganizes to prepare the cell for cytokinesis (cell division).
