Answer:
d. Hemoglobin helps maintain a constant pH in the blood by binding with H⁺ions released from bicarbonate ions.
Explanation:
The presence (CO₂) in in the erythrocytes lowers its pH as a result the affinity of hemoglobin decreases for oxygen. The carbon dioxide (CO₂) reacts with water to form carbonic acid in the presence of the enzyme carbonic anhydrase which is present in the erythrocytes or red blood cells. The carbonic acid then changes into two ions hydrogen ion (H⁺) and bicarbonate ion (HCO₃⁻). As a result of H⁺ ions, the pH of blood drops. Haemoglobin pick up hydrogen ions to balance the decrease in pH. Thus, haemoglobin helps in maintaining constant pH or keep pH of blood in buffer.

Hope you have a great day :)
Answer:
The correct answer will be- will be called "Clones" with no genetic variation thus result in less adaptability to environment.
Explanation:
Plants can reproduce by both modes of reproduction called asexual and sexual reproduction. The asexual mode of reproduction produces genetically similar offsprings in less period of time and thus helps in spreading of the species in minimum time as in the case of Kalanchoe.
The Kalanchoe can dominate a large area of the habitat using this mode of reproduction but at the cost of genetic variation.
Since asexual reproduction results in Clones with same genetic material so the descendants of the plant will be less adaptive to changing the environment as asexual reproduction does not involve genes.
