Red blood cells are disc shaped. It is thought one factor that allows them to have this shape is because they do not have a nucleus. This tends to increase amount of space inside the cell for hemoglobin.
They have a flexible disc shape which helps increase the surface- to- area volume ratio which enables oxygen and carbon dioxide to diffuse across the red blood cell's plasma membrane more readily.
Their disc shape also enables them to squeeze through tiny capillaries that are half their size .
The pattern of change in CO₂ concentration is new plant growth in the spring increases photosynthesis rates, which lowers CO2 concentrations; this decline continues until autumn, when leaves fall and decompose, raising CO2 concentrations.
The level of carbon dioxide within the surroundings rises and falls every 12 months as plant life, thru photosynthesis and respiration, absorbs the gas in the spring and summer season, and launches it in fall and wintry weather. Now the range of that cycle is expanding as extra carbon dioxide is emitted from burning fossil fuels and different human activities.
In spring, flora in the Northern Hemisphere starts to develop and absorb CO2 from the atmosphere, so atmospheric CO2 attention decreases as the road dives down. In fall, flora starts to decay and release their CO2 again into the ecosystem, so atmospheric CO2 attention increases the line shoots up. plants are accumulating carbon within the spring and summer while they are lively, and they're liberating carbon again to the air in the fall and winter.
