Homework Answers
its a clear fact as we can see that our oil field are depleting day by day. now if we can able to find a chemical reaction which can produce large amount of energy by reacting a very small amount of mass, then it can be a revolutionary idea.
if we can able to produce such reactions then our living standard will increases as we can see that without energy nothing is possible.

Discuss our body’s physiological adaptation to modern diet. In your answer explain how and why today’s diet is different than what Homo sapiens used to eat 10-12kya. Did we adapt to this diet? If so, how did we adapt (discuss at least 2 different genes in your answer, 300 words, at least 4 academic references in JBC format)?

ENERGY FROM CHEMICAL REACTIONS (page 8) Many chemical reactions release energy, while others require energy to happen. These energy changes that occur during chemical reactions are due to changes in bonding between the reactant molecules and product molecules. Breaking bonds between atoms always requires energy, while creating bonds between atoms always releases energy. Analyze each of the two chemical reactions below by calculating the total amount of energy needed to break the bonds in the reactants, the total amount of...
