WebAnswer: First, I would like to clarify that concentration of oxygen in the body is measured in terms of partial pressure, and not in terms of density. The term partial pressure refers to the fraction of pressure that a specific gas exerts as compared to the total pressure in the closed container.... WebThus, dissolved oxygen concentrations will typically be highest in the mid- to late afternoon when photosynthesis rates are greatest, and will reach the lowest concentrations just before the sun rises the next morning due to respiration needs. This fluctuation pattern is referred to as the "diurnal oxygen cycle" (Figure 2). gpu unknown photoshop https://asadosdonabel.com
