As we move right in the periodic table, both atomic number and atomic mass increases. Magnesium comes under S-block elements (Group 2) and Phosphorus comes under P-block elements (Group-15).
Carbon dioxide with the help of diffusion reach the other cells in the leaf and the oxygen which is produced during the process of Photosynthesis is diffused out of the leaf. Hence, diffusion is the simple process by which gaseous exchange takes place.
99% percentage of errors does our body's "auto-correct",system detect.
Errors associated with protein mismatch and translation is automatically detected by the body system. Once, mismatch occurs, synthesis stops, hence, this error is almost always detected at all times. Therefore, the percentage of errors automatically detected is about 99%.
