During heavy exercise, the po2 in muscle may drop to 20 mmhg. Considering the oxygen-hemoglobin dissociation curve shown, what is the approximate percent o2 saturation of hemoglobin in venous blood returning from skeletal muscles during heavy exercise?.

Thermohaline circulation and gyres

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The answer is bhope this

Answer (b) supersaturation;
