Plate tectonic induced changes in the sea level could increase the total percentage of land area upto 40% or decrease it to as low as 17%
<h3>What are Tectonic plates?</h3>
Plate tectonics, whose name derives from the Late Latin tectonicus and the Ancient Greek letter v, which means "pertaining to building," According to the widely accepted scientific idea , the Earth's lithosphere is made up of many major tectonic plates that have been gently shifting for nearly 3.4 billion years
The model is based on the idea of continental drift, which was created in the early 20th century. After seafloor spreading was confirmed in the mid- to late 1960s, plate tectonics became largely accepted by geoscientists.

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.
