Answer:
vaccination
Explanation:
The vaccination has been one of the most revolutionary inventions in the medical field. This invention helped protect people from numerous diseases, some being totally neutralized, while some having only minor effects on the human body. The vaccination basically is a way of enhancing the immune system of the body by injecting in it a weakened form of the pathogen. In this way, the weakened form of the pathogen is not capable to harm the body, and the body is not fighting against it, but instead the pathogen becomes part of the body and its defense mechanism, so when the pathogen strikes, the body has a counter attack and defeats it.

Answer: (c) It generates ATP, which cells can use to do work.
(d) It generates chemical gradients, which have potential energy.
Explanation:
The overall process of Cellular respiration is the aerobic break down of organic compounds (food) with the release of CO2, water and energy in form of ATP which drives most cellular work.
Organic compound + oxygen --------> carbon dioxide + water + energy (ATP + heat)
In cellular respiration during the break down of food in glycolysis and the citric acid cycle, chemical energy (NADH and FADH) are extracted from each cellular process and transported to the electron transport chain built in the inner mitochondrial membrane. The chemical energy harvested from food is transformed into a proton-motive force, a gradient of H+ across the membrane. When this H+ election fall from their gradient via ATP synthase, Chemiosmosis couples this proton motive force to phosphorylate ADP to form ATP.
<u>Answer:</u>
The invention of agriculture, advances in medical technology that have greatly reduced the human death rate and he rapid increase in the uses of fossil fuels, fertilizers, metal ores, and other resources.
Option: (A), (C) and (D)
<u>Explanation:</u>
- The Great Acceleration refers to the humanity’s impact upon the Earth’s geology and its ecosystems caused by continual and surge in growth of human activity.
- It was first recorded in mid-20th century and is continuing to this day. The 'invention of agriculture', advancement in medical technology which reduced the death rate, rapid increase in use of 'fossil fuels', 'fertilizers' and other resources contributed to global changes.
- Agriculture allowed us to produce more food and population increased rapidly.
- Fossil fuels created a surge in production of Green House Gases and global temperature began to rise.
