Natural phenomena can be considered as extremely important events for our planet, as they influence the climate and the life of the species that exist on it. For example, rains are necessary to keep the rivers and lakes full and thus ensure drinking water for all living beings that depend on it to survive. Which of the following is an example of a natural phenomenon that contributes to the balance of the Earth?

Plants are very important living beings for our world, and each part of them has a special function. The root helps the plant stay in place and take water from the soil, the stem holds the plant up and carries water to the leaves, the leaves use sunlight to make food, the flower attracts insects and animals to aid in reproduction, the fruit protects the seeds and helps the plant spread. With that in mind, choose a plant you know, like a flower you have at home or a tree from school, and describe a function for each part of that plant: root, stem, leaf, flower, and fruit. Explain why each of these parts is important for the plant to live and grow healthily.

The evolution of the Solar System is a complex process that involves the formation of stars, planets, and other celestial bodies from a large cloud of gas and dust. Studying this evolution not only expands our knowledge of the cosmos but also allows us to understand fundamental aspects of physics and chemistry. On the other hand, ancient cultures developed mythologies and interpretations about the origin and evolution of celestial bodies, often based on astronomical observations and their own traditions. Considering the historical and scientific context, describe the evolution of the Solar System from its beginning in a molecular cloud to the formation and stabilization of planets. Explain how the observations and interpretations of ancient cultures can be related to this evolutionary process, even though they did not have the scientific knowledge we have today.
