Creation of a social utopia
Answer:
The 6 Main Elements are Hydrogen, oxygen, carbon, Nitrogen, calcium & phosphorus
Explanation:
99% of the atoms in the human body come from 6 elements: Hydrogen at about 63%, oxygen (around 25%), carbon (nearly 11%), nitrogen (nearly 0.7%), calcium (0.25%), phosphorus (0.15%) and Calcium which is essential for our bones, & contains 99% of the calcium in the human body
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>
Answer: Amazon are the largest rainforests in the world.
Explanation:
The Amazon Rainforests are located in the northern South America. The following are the ways in which the Amazon rainforests are important to the world.
1. The Amazon Rainforests can regulate the major cycles like water cycle, carbon cycle and oxygen cycle necessary for maintaining the aesthetic qualities of the environment. These are also necessary for maintaining the weather patterns. These phenomena makes the earth habitable.
2. These forests provides accommodation to 30 million native people. These forests are also the source of 10% if the total world's biodiversity.
