Answer 1

Resposta:

Sobre a água: Water is the source of life. No matter who we are, what we do, where we live, we depend on it to live. However, great as it is the importance of water, people continue polluting the rivers and its sources, forgetting how much it is essential to our lives. The majority of each of the cells in our body has water. We use the water for drinking, preparing meals for the personal and home care, or for fishing, transportation, electric power production, irrigation etc.

In nature, there are several types of water, depending on the elements it contains. Some are ideal for consumption, while others are harmful to health. Are they:

1. Drinking water: the ideal type for consumption, is fresh and free of impurities;

2. Polluted water: it is dirty or contaminated water, i.e., it contains impurities, microbes, viruses, etc;

3. Fresh water: the water of rivers, lakes and sources;

4. Salt Water: is the one that contains many dissolved salts, for example seawater;

5. Distilled water :is composed of hydrogen and oxygen only, no impurities and any dissolved salt;

A água é a fonte de vida. Não importa quem somos, o que fazemos, onde vivemos, nós dependemos dela para viver. No entanto, por maior que seja a importância da água, as pessoas continuam poluindo os rios e suas nascentes, esquecendo o quanto ela é essencial para nossas vidas. A maioria de cada uma das células no nosso corpo tem água.

sobre a energia:

Renewable energy is one that comes from natural resources that are naturally replenished, such as sun, wind, rain, tide and geothermal energy. It is important to note that not all natural resources are renewable, for example, uranium, coal and petroleum are removed from nature, but they exist in limited quantities. In 2008, about 19% of world energy consumption came from renewable sources, with 13% coming from traditional biomass, which is used primarily for heating, and 3.2% from hydroelectricity. New renewable energies (small hydropower, biomass, wind, solar, geothermal and biofuels) accounted for another 2.7% and this percentage is growing very rapidly. The proportion of renewable energy in electricity generation is around 18%, with 15% Of global electricity from hydroelectric plants and 3% of new renewable energy.The sun's energy is converted in many ways into known formats, such as biomass (photosynthesis), hydroelectric power (evaporation), wind (wind) and photovoltaic energy, which contain an immense amount of energy and are able to regenerate By natural means.
