Can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). they can cause termination (death) of an organism or they can be partially lethal.
Answer: the two tropics zones
Explanation:
Between the two tropics zones, which includes the equator, the Sun is directly overhead twice per year. Outside the tropic zones, whether to the south or north, the Sun is never directly overhead. Two other significant lines of latitude are the Arctic Circle (around the North Pole) and the Antarctic Circle (around the South Pole).
In hemoglobin, the transition from t state to r state (low to high affinity) is triggered by Bisphosphoglycerate (BPG)
- Bisphosphoglycerate (BPG), also known as 2,3-Disphosphoglycerate (2,3-DPG), aids in the transition of hemoglobin from a high-oxygen-affinity to a low-oxygen-affinity state.
- 2,3-BPG binds to hemoglobin, causing oxygen to be unloaded. Furthermore, 2,3-BPG reduces hemoglobin's affinity for oxygen. As hemoglobin is unloaded in our tissues, 2,3-BPG binds to it, promoting oxygen unloading.
- When we increase the concentration of 2,3-BPG in our blood, the oxygen binding curve shifts to the right. This means hemoglobin will have a lower affinity for oxygen and will be able to deliver more oxygen to our body's tissues and cells.
