Answer:
<h3>Plessy v. Ferguson case.</h3>
Explanation:
- The Plessy v. Ferguson case of 1896 ruled out that segregation was constitutional as long as both blacks and whites enjoyed opportunities that were separate but equal.
- However, the Supreme Court's verdict in the Plessy v. Ferguson case of 1896 was challenged by Justice Earl Warren stating that the idea of ‘separate but equal’ in public school was unconstitutional and inherently unequal.
- Thus, Chief Justice Earl Warren issued the Supreme Court’s unanimous decision in Brown v. Board of Education, ruling that racial segregation in public schools violated the "Equal Protection Clause” of the 14th Amendment.
Answer:
O2 affinity depends on the pCO2 and pH.
Higher pH -> Higher O2 affinity -> Higher O2 saturation at higher pH level
Higher pCO2 -> Lower O2 affinity -> Higher O2 saturation at lower pCO2 level
This is a benefit because it allows the affinity of Hb in venous blood conditions (lower pO2, higher pCO2, and lower pH) to be much lower than in arterial conditions. Therefore, when blood goes from arterial to venous, the oxygen concentration decreases much more dramatically due to more oxygen (around 2x) being released to the tissues, which is possible due to the changes in affinity caused by the Bohr effect.
