The Modern World, where everything is artificial and ephemeral; where you have to pay for a "need" created or for clean air.
The greed of man to generate wealth and status regardless of the impact it generates on his environment, to be accepted by his family and society.
Unsustainable production systems, which destroy ecosystems and alter the life of the animals that live there.
Children living in the Modern World, who know little about the nature and the effect of our actions on the environment.
Caring for the environment is in the hands of the new generations, especially those who really care.

<span>A woman's ovary is sixteen times the size of a single sperm. This allows said sperm, or any of its friends, to penetrate the ovary with ease and precision. The ovary will also serve as the home for this sperm during its growth, proving that its larger size has multiple purposes in assisting in sperm growth.</span>
Answer:
Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).
Explanation:
Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.
During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.
With respect to the law of conservation of energy, it is necessary to consider:
- In the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.
- Energy in an isolated system does not vary, unless it comes into contact with another system.
- The amount of energy that is absorbed and obtained is equivalent.
In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.
Regarding other options:
<em> 1. In photosynthesis, it is not </em><u><em>mechanical energy</em></u><em> that is transformed into chemical energy.</em>
<em> 3. </em><u><em>Oxygen is a product of photosynthesis</em></u><em>, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.</em>
<em> 4. It is true that the </em><u><em>sun gives off light energy that is absorbed by plants</em></u><em>, but it does not explain how this energy is transformed into chemical energy.</em>
The answer is B cell wall
