As a result of Columbus's voyages to the New World, a biological pipeline between America and Europe opened up that had been apart since before humans appeared on earth. The lands had drifted apart that had once been connected. Some species of plants and animals flourished in both areas, and some did not. There were many new animals and plants in the Americas that Europeans had never seen. And, Europeans brought plants and animals to the New World that America had never seen. This includes viruses and other biological organisms. The new animals brought to America upset the ecology of the area. The people living in the Americas did not have resistance to many of the "germs" brought by the Europeans. Biologically, the Indians had not been exposed to measles, smallpox, whooping cough, chicken pox, and influenza. The effect of these diseases on the Americans was catastrophic. Bacteria and viruses killed more Native Americans than did Spanish swords. The Indians also gave to the Europeans, venereal disease. Medical historians disagree on the origins of syphilis, but it was first identified by physicians in 1493, in Cadiz, Spain, the port which Columbus returned to after his first voyage. The Colombian Exchange was also a cultural exchange. New agricultural developments were traded, economic activity and opportunities opened up between the New and Old Worlds, and new ideas were exchanged.

The arrows in the image define the equation as . decomposition exchange reversible synthesis?

It appears that you are asking about a chemical reaction that involves different processes. In this context, "decomposition" refers to breaking down a compound into simpler substances, "exchange" indicates a reaction where components are swapped between compounds, "reversible" implies that the reaction can proceed in both the forward and reverse directions, and "synthesis" involves combining simpler substances to form a more complex compound. The arrows in the image likely represent the direction and nature of these reactions.

Is there a Thermodynamic system in a living organism?

Yes. If you define the entire organism as your "system" (i.e. you set the boundaries of the system to include everything this is part of the organism or contained within it ), you can measure thermodynamic properties and perform calculations on that system. Thermodynamic systems are typically defined in terms of how (or if) they interact with their environment. An "open system" is one where the defined volume exchanges both mass and energy with its environment A "closed system" is one where the defined volume may exchange energy with its surrounding environment but the mass within the system remains constant. An "isolated system" is one where neither mass nor energy cross the boundaries of the system. Most likely you would define the thermodynamic system of the organism as an "open system". If you seal it off so that no mass can enter or leave the system it would probably die pretty soon.


How can avoid rewarding the wrong behaviors?

Clearly define desired behaviors and provide rewards only when those behaviors are demonstrated. Offer feedback and coaching to redirect individuals who engage in the wrong behaviors. Consider implementing consequences for repeated instances of wrong behaviors to discourage them.


Why are simpler societies disappearing?

Simpler societies are disappearing primarily due to globalization, which promotes economic integration and cultural exchange, often at the expense of traditional ways of life. As modern technologies and industries expand, they encroach on indigenous lands and resources, leading to cultural assimilation and loss of indigenous practices. Additionally, urbanization draws younger generations away from rural areas, resulting in declining populations in simpler societies. This shift often leads to the erosion of languages, traditions, and social structures that define these communities.
