Explanation:
Prehistoric hominids evolved opposable thumbs earlier than bipedal walking. The opposable thumbs have been critical during evolution because this position enables the digits to grasp and handle objects.
The element needed for cellular respiration is oxygen. Oxygen is essential in the final stage of cellular respiration, the Electron Transport Chain, where it acts as the final electron acceptor. The absence of oxygen would lead cells to resort to anaerobic respiration that yields less energy.
The element needed for cellular respiration is oxygen. Cellular respiration is a process by which cells break down glucose and other molecules in the presence of oxygen to produce energy. The process can be broken down into three stages: Glycolysis, Krebs Cycle (Citric Acid Cycle), and the Electron Transport Chain. Oxygen plays a crucial role in the final stage, the Electron Transport Chain, where it acts as the final electron acceptor and combines with the hydrogen ions to form water.
Without oxygen, the Electron Transport Chain cannot occur. If oxygen is not available, cells may resort to an alternative method known as anaerobic respiration, or fermentation, but this produces significantly less energy. Hence, oxygen is a vital element required for efficient cellular respiration.

How are environmental issues becoming more complex?
What about the history of environmental studies can inform us about our current environmental issues? Why is it important to understand the past to help solve current and future environmental problems?
Answer:
Most environmental issues are problems on a global scale, these include but are not limited to, global warming, ozone pollution, greenhouse gases and many more issues.
This affects the way we try to solve these issues because if we dont all play a part to help change the way things are going, then they will only get worse. We have to come together as a whole.
Unlike individual efforts, different countries can cooperate and implement legislation which limitates all the countries in the globe,solving environmental issue more efficiently.
