Answer:
The two species are from the same kingdom but only two differ. They cannot made and produce offspring.
Explanation:
Answer:
Ability to deliver 
increases.
Explanation:
Carbon dioxide is transported by the blood in the dissolved form. carbonic anhydrase is the enzyme which is a metalloenzyme having zinc at active site converts carbon dioxide into carbonic acid which dissolves in the blood.
Thus,
H₂O (l) + CO₂ (g) ⇔ H⁺(aq) + HCO₃²⁻(aq)
If the concentration of the carbon dioxide is increases, then there is increase in the concentration of the hydrogen ions and thus decrease in the pH which results in the hemoglobin proteins releasing the uptake load of the oxygen. (Bohr effect)
Answer;
The above statement is True.
Explanation;
-Biotic factors are the living components of an ecosystem and are sorted into three groups: producers or autotrophs, consumers or heterotrophs, and decomposers or detritivores.
-Producers are living things within an ecosystem that make life possible for all other organisms. This is because they produce something very important. They are important parts of an ecosystem. Producers are the green plants. They make their own food. Consumers on the other hand are animals and they get their energy from the producers or from organisms that eat producers.
