Answer:
b) a graphical representation of the relationship between hemoglobin's percent saturation and the partial pressure of oxygen
Explanation:
On vertical axis-hemoglobin's oxygen saturation
On horizontal axis-oxygen partial pressure
This curve determines hemoglobin affinity for oxygen. If hemoglobin has high oxygen saturation, hemoglobin's affinity for oxygen is high.
As the blood moves through the systemic capillary, hemoglobin's affinity for oxygen decreases, so that oxygen can be released into the cells.
The height wind waves or waves generated by the wind are surface waves that occur on the surface of oceans, lakes, rivers, seas and canals etc. Waves can travel thousands of miles before reaching land. They range in size from small ripples to over 100 foot high. They are dependent on the following three things:
1. Wind speed - the height of waves is dependent on the speed of the wind. The faster the wind, the higher the waves and vice versa. 2. Wind direction - the height of waves is dependent on whether the wind is blowing offshore or onshore. Offshore winds blow from the land onto the sea so tend to cause bigger waves3. Storm winds in a cyclone or hurricane. These winds travel in circles around the eye of the storm and are usually very high in intensity. Depending on the intensity of the wind and the speed at which the wind is travelling, the wave height will differ.
This is an example of microevolution.
Microevolution represents a small change in the genetic structure of the population. These changes manifest through the change in the allele frequencies of genes like in the case of dung beetles.
The causes of microevolution are evolutionary mechanisms, natural selection, genetic drift, mutations and gene flow.
Cholera occurs when the G protein cannot hydrolyze GTP to GDP so the G protein is always active. This causes water and salt to leak out causing diarrhea and eventually death by dehydration.
