Increased temperature results in decreased o 2 unloading from hemoglobin. and oxygenated hemoglobin releases oxygen more readily when the ph is more basic. true false

False.

Explanation:

Temperature affects affinity of hemoglobin for oxygen. Increase in the temperature, decreases affinity of the hemoglobin for oxygen.

But,  

Carbon dioxide is transported by blood in the dissolved form. Carbonic anhydrase is the enzyme which converts carbon dioxide into carbonic acid which further dissociates to proton and bicarbonate ion and these ions dissolves in the blood and is reached at the lungs.

H₂O (l) + CO₂ (g) ⇔ H₂CO₃ ⇔ H⁺(aq) + HCO₃²⁻(aq)

An increase of the acid in the blood results in the decrease in blood pH, resulting in the hemoglobin proteins releasing bonded  oxygen. On the other hand,  decrease in the carbon dioxide makes the increase in pH, which results in the hemoglobin picking up more oxygen.

Hence, the statement is false.

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
