During a classroom experiment, 6th-grade students decided to investigate the time it takes for different types of food to pass through a simulated human digestive system. The tested foods were a whole wheat bread and cheese sandwich (carbohydrates and proteins) and an apple slice (mainly carbohydrates and fibers). To simulate chewing, the foods were mashed into similar-sized pieces and mixed with a solution of water and digestive enzymes that mimics the action of saliva. From the observations made in the experiment, the students noticed that, despite being broken into smaller pieces, the sandwich and the apple did not completely mix at the beginning of the digestion process. Considering their knowledge about the human digestive system and the experiment conducted, discuss the relevance of the students' observation for understanding the digestion process and explain how the structure and action of digestive enzymes can act differently on the different components of these foods. Additionally, analyze how the interdisciplinary approach between Science and Mathematics could be applied to estimate the digestion time of each type of food based on known enzyme reaction rates.a.
The students' observation that the sandwich and the apple, despite being in smaller pieces, did not completely mix, reflects the beginning of the digestion process, which occurs in a segmented manner, and the interdisciplinary approach between Science and Mathematics can be used to estimate the digestion time of different foods.
b.
The students' observation that the sandwich and the apple did not completely mix indicates that the mixture of enzymes and foods was not done correctly, compromising the experiment results.
c.
The fact that the sandwich and the apple did not completely mix at the beginning of the digestion process is an indication that the chewing in the experiment was not effective, affecting the action of digestive enzymes.
d.
The lack of complete mixing between the components of the sandwich and the apple at the beginning of the digestion simulation is a sign that the digestive enzymes present in the solution were not active, making the analysis of digestion time unfeasible.
e.
The segmentation of the sandwich and apple components at the beginning of the digestion process, without complete mixing, indicates that the digestion of each food occurs in different compartments of the digestive system, without interaction between them.

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.

Technological development has allowed the exploitation of natural resources in an increasingly intense way. However, this unrestrained exploitation has generated serious environmental problems. Deforestation is an example of these problems. Deforestation is the destruction of forest cover for agricultural use, urbanization, or timber extraction. Which of the following environmental impacts can be caused by deforestation?

You must have noticed that the materials we use in our daily lives can change when placed in different situations. For example, water can change its form when heated to make tea, or what happens to fruit when left out of the refrigerator for too long. Think of a material you know and explain how it could change if placed in four different situations: (1) exposed to strong sunlight, (2) placed in the freezer, (3) mixed with another material that reacts with it, and (4) cut into very small pieces. Write about the changes this material could undergo and what causes this change, explaining what happens at the particle level of the materials.
