Answer:
B. Pulmonary Circulation
Explanation:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart.
Davis believed that he and his fellow citizens had the right to rebel against the government if it failed them
Our present condition, achieved in a manner unprecedented in the history of nations, illustrates the American idea that governments rest upon the consent of the governed, and that it is the right of the people to alter or abolish governments whenever they become destructive of the ends for which they were established.
Explanation:
Answer:
a) Change in internal energy of the system = - 135.2 J
b) Change in internal energy of the environment = 135.2 J
Explanation:
From the mathematical statement of the first law of thermodynamics,
ΔU = Q - W
ΔU = Change in internal energy of the system = ?
Q = heat transferred into or out of the system. For this system, heat is transferred into it, Q = 77.8 J
W = workdone = 213 J (positive because work is done by the system on the environment)
ΔU = 77.8 - 213 = - 135.2 J
The change in internal energy of the environment is just the negative of that of the system. The balance is always so.
Hence, change in internal energy of the environment = -(- 135.2) = 135.2 J
Answer:
They may have different phenotypes because of differences in their environments, such as nutrition and healthcare. Why might genetically identical twins have different phenotypes? Any genes on the same chromosome could be linked genes, whereas only genes on sex chromosomes can be sex-linked genes.
Explanation:
Copper oxide reacts with hydrochloric acid to produce copper chloride and water.
So the basic equation that illustrates this reaction is:
CuO + HCl ......> CuCl2 + H2O
Now, we need to balance this equation:
the number of copper and oxygen moles are balanced.
For each of hydrogen and chlorine, we have one mole as a reactant and two moles as product.
Therefore, to balance this, we will add an extra mole of HCl in the reactants.
Based on this, the final balanced equation would be:
CuO + 2HCl ................> CuCl2 + H2O
