- A.
Cerrado
- B.
Abierto
- C.
Combinados
- D.
Avanzado
Correct Answer
B. AbiertoExplanation
An open system is a system in which the structure of the living being is dependent on the existence of an energy flow. This means that the living being is able to exchange matter and energy with its surroundings. In an open system, there is a constant input and output of energy, allowing for growth, development, and adaptation to the environment. This is in contrast to a closed system, where there is no exchange of energy with the surroundings, and a combined system, which is a combination of open and closed systems. The term "advanced" does not provide any relevant information in relation to the given explanation.Rate this question:

- A.
Nitrógeno
- B.
Fósforo
- C.
Carbono
- D.
Agua
Correct Answer
B. FósforoExplanation
The correct answer is "Fósforo." This is because phosphorus is an essential nutrient that cycles primarily in sediments. It is often found in the form of phosphate minerals in rocks and sediments, and it is released into the water through weathering and erosion processes. Once in the water, phosphorus can be taken up by plants and algae, and it eventually returns to the sediments through the decomposition of organic matter. Therefore, the majority of the phosphorus cycle occurs in sediments.Rate this question:

Se considera una lluvia acida aquella que presenta un pH menor de:
- A.
10.65
- B.
9.65
- C.
7.65
- D.
5.65
Correct Answer
D. 5.65Explanation
An acid rain is defined as rainwater with a pH level lower than 5.65. This means that the rainwater is more acidic than normal, which can be harmful to the environment. Acid rain is caused by the emissions of sulfur dioxide and nitrogen oxide from burning fossil fuels, which react with water in the atmosphere to form sulfuric acid and nitric acid. These acids can have detrimental effects on plants, animals, and infrastructure, making it important to monitor and reduce the emissions that contribute to acid rain.Rate this question:
