<span>In marine vertebrates, the gill arches use the external gas exchange. The water holds less oxygen.
The ribs in terrestrial vertebrates have enclosed respiratory surface which is inside the body and comes as paired lungs.

Answer:1Zn+2HCl------1ZnCl2+1H2
Explanation:
A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The answer to this question would be leukopenia.
Leukopenia is a condition where the total white blood cells count is too low. White blood cell is fighting the microbes, so decreased of their number might cause the patient immune system to be decreased to, leading to immunocompromised status.
