Answer: The Principle of Original Horizontality
Explanation: The Principle of Original Horizontality states that layers of sediment are at first deposited horizontally below the movement of gravity. It is a relative relationship technique. The precept is critical to the evaluation of folded and tilted strata.
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.

The greater the attractive forces between substrate and enzyme, that
enzyme is said to have a higher affinity for the substrate.
<h3>What is an Enzyme?</h3>
This is a substance which acts as a catalyst in regulating the biochemical
processes of the body.
Enzymes are substrate-specific which means they act only on some types
of compounds. For example the enzyme protease acts only on protein.
When the attractive forces between substrate and enzyme is great then
the enzyme is said to have a higher affinity for the substrate.

The proteins(particularly enzymes) of the membrane help chemical reactions.
An example would be enzymes involved in electron transport chain.
