In the context of the human body, the circulatory system plays a fundamental role in transporting nutrients, oxygen, and essential substances, as well as removing metabolic waste. This system is composed of the heart, blood vessels, and blood, which together act in an intricate circuit of high and low pressure. Considering the following excerpt from a poem that makes a poetic analogy with the blood flow, 'The heart, in a pulsating orchestra, conducts the blood through the body like a maestro conducting the symphony of life, while the veins and arteries are the paths through which the red and white messengers glide, carrying mysteries and secrets', and knowing that arterial blood and venous blood have distinct characteristics and functions, explain the role of arteries and veins in the circulatory system and the main difference between the blood circulating in each of these types of vessels.a.
Arteries carry oxygen-rich blood and nutrients from the heart to the body, while veins return oxygen-poor and waste-rich blood to the heart. The main difference between arterial blood and venous blood is the content of oxygen and carbon dioxide, as well as the color and brightness of the blood.
b.
The main difference between arteries and veins is the direction of blood flow: arteries carry blood from the heart to the body and veins carry it from the body back to the heart, without other distinctions.
c.
As arteries collect oxygen-poor blood from the cells and carry it to the heart, while veins distribute oxygen-rich blood and nutrients to the body tissues.
d.
Both arteries and veins transport oxygen-rich blood and nutrients from the heart to the body and vice versa, with no differences between the type of circulating blood.
e.
Veins are responsible for pumping blood from the heart to the tissues, while arteries collect blood from the tissues and transport it back to the heart.

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.

Imagine that you and your family went camping near a lake for the weekend. Looking at the lake, you remembered that the water there could have passed through many places and been in different forms. Think about the sun heating the lake water, it turning into vapor and rising to the sky, the clouds loaded with vapor, and then the rain falling back into the lake. Describe what happens to the water during this journey, from the lake evaporated by the sun to the rain falling back into the lake, and explain the role of the sun in the water cycle.

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.
