I’m gonna say it’s either “living” or “critical” sorry if this isn’t much help but at least it’s narrowed down
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.
The matter can be classified in two different ways; (a) according to its state, and (b) according to its composition. Matter can exist in three different states, solid, liquid, and gas, based on the way the atoms and molecules are arranged inside them.
Plants grow towards the sun due to the chemicals produced inside of their stems.
Answer: To split into two or more daughter cells
Explanation:
Interphase is the first stage in cell division (mitosis and meiosis). During the stage, the parent cell acquire nutrients, increase in size and duplicate its cellular contents (chromosomes, organelles etc) before heading into four other stages (Prophase, Metaphase, Anaphase and Telophase) meant to generate the individual daughter cells capable of independent living.
