Answer:
Evolutionary ideas do not contradict the thermodynamic laws, these ideas explain how descent with modification enables the organisms to have enhanced metabolic responses to fight against entropy
Explanation:
Organisms fight against entropy to maintain order within their cells and thus continue life. The debate about the association between the Second Law of Thermodynamics and evolutionary ideas emerged in 1900. During this period, it has been proposed that both ideas were contradictory, since evolution decreases entropy, while the second law states that systems increase entropy over time. However, the evolution does not contradict this law, because evolutionary ideas indicate the mode by which the organisms evolve to fight against entropy (for example, by enhancing enzymes responsible for protein degradation), while the Second Law of Thermodynamics literally states that the total amount of entropy of the whole system increases over time.
Hemoglobin is a molecule with a central iron atom responsible for carrying oxygen in your blood cells, as a result, when an oxygen atom bonds to the iron atom, hemoglobin causes the blood to appear bright red (think of it like iron rusting due to exposure to oxygen).
Veins appear blue due to how light reflects off of the various tissues but our blood is NOT blue when it isn't exposed to oxygen.
Arteries have oxygen-rich blood and veins have oxygen-poor blood. Veins carry blood toward the heart and arteries carry blood away from the heart. You can remember this easily because our cells need oxygen and, because arteries carry oxygen-rich blood, they are responsible for carrying blood away from the heart to the different parts of our bodies.
Veins carry the oxygen-depleted blood back toward the heart so it can become oxygen-rich again.
I'm guessing for no reproduction of other human beings
As science grows a better understanding of how things works plants and animals and everything else that lives they find better ways to classify them.
its adding co2 into the air also known as the green house gases
