Inhaled oxygen moves from the alveoli to the blood in the capillaries, and carbon dioxide moves from the blood in the capillaries to the air in the alveoli. This is what happens in the alveoli during gas exchange
Given what we know, we can confirm that the "balance of nature" refers to a scientific theory about ecological homeostasis.
<h3>What does ecological homeostasis mean?</h3>
- This refers to the idea of a perfect balance in an ecosystem.
- It is the theory that all aspects of an ecosystem are and will remain balanced even if there are small changes.
- This implies that any minor change in an ecosystem will be corrected.
- This will happen through natural regulation mechanisms such as positive or negative feedback.
Therefore, we can confirm that the "balance of nature" is the scientific theory that all things in an ecosystem will remain balanced, meaning that if there is a small change, it will be corrected through some form of natural regulatory mechanism.

Answer:
C
Explanation:
Bauxite is the most common aluminum ore. Approximately 98% of primary aluminum production is based on bauxite. In the former Soviet Union, aluinite and kaolinite are also used in small proportions for aluminum production. Bauxite is a naturally occurring, heterogeneous material composed primarily of one or more aluminum hydroxide minerals plus various mixtures of silica, iron oxide, titania, and other impurities in trace amounts. The principal aluminum hydroxide minerals found in varying proportions within bauxite are gibbsite (trihydrated) and boehmite and diaspore (both monohydrated). The content of aluminum oxide is 30–60%. Bauxite is generally extracted by open cast mining from strata, typically 4–6 m thick under a shallow covering of topsoil and vegetation (Table I).
