Explanation:Most plants the manage to grow from bricks and or concrete are mostly weeds that do not need light to grow. They are 100% dependant on if they get any sun or not. If you put seeds under concrete they would not make it, if you put them in a crack in concrete they might have a chance it all depends on the light they get.
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.

You can classify them according to the way they get their food because if they eat plants, then they are herbivores. If animals eat herbivores, then they are consumers. Etc.
