Which of the following workers is a maintenance staff member?
Answers
1. Juan es un estudiante joven que hace poco se mudó a su propio departamento. Realiza actividad física desde siempre pero últimamente nota que se cansa más rápido, tiene poca fuerza y ha perdido algo de peso. No entiende la causa porque sigue comiendo en forma abundante. Visita a su médico, quien le informa que tiene pérdida de masa muscular y le pregunta si está alimentándose correctamente. ¿Por qué le hace esta pregunta? ¿Qué tiene que ver la comida con el músculo?
Answers
Answer:
Es posible que Juan sospeche que no está alimentándose correctamente (comer en grandes cantidades no significa estar bien alimentado)
Explanation:
Las proteínas representan un macronutriente esencial que debe ser consumido a través de la dieta para crecer en masa muscular y también para mantener la masa de los músculos. Las proteínas están compuestas por muchos tipos diferentes de aminoácidos (los bloques de construcción de las proteínas), pero solamente 20 aminoácidos conforman las proteínas que se encuentran en el cuerpo humano. Los aminoácidos esenciales son aquellos que el cuerpo no puede sintetizar por sí solo. Estos aminoácidos esenciales son: histidina, fenilalanina, treonina, lisina, metionina, triptófano, valina, isoleucina y leucina. El consumo diario recomendado por la Organización Mundial de la Salud (OMS) de proteínas en un hombre adulto es 0,8 a 1 gramo por kilogramo de peso corporal. Además, es posible que el cansancio que experimenta Juan se deba a alguna deficiencia en micronutrientes esenciales, es decir, debido a la falta de vitaminas y minerales, los cuales también deben ser consumidos a través de la dieta. Por ejemplo, la fatiga puede deberse a la falta de hierro, un mineral fundamental cuya deficiencia lleva a cuadros severos de anemia. Similarmente, la deficiencia en vitamina D puede también causar agotamiento o fatiga crónica, entre otros síntomas (por ej., abruptos cambios en el estado de ánimo, debilidad ósea en los huesos, daño en el estómago, etc). Por otra parte, es importante remarcar que no se debe descartar la posibilidad de que el cansancio experimentado por Juan se deba a un cuadro de estrés y/o algún otro tipo de problema de salud, siendo por lo tanto necesario una descripción más detallada del cuadro clínico para obtener una conclusión más precisa de su situación.

Justify your answer and provide at least two resources to back up your answer (your textbook should be a resource) (10 points; at least 300 words)
Answers
Aquaculture can be a useful practice for the environment and food systems. However, it must be implemented responsibly to minimize negative impacts. Proper waste management, disease control, and careful site selection are essential for sustainable aquaculture.
Aquaculture is the practice of farming aquatic organisms, such as fish and mollusks, in controlled environments. It has both benefits and problems associated with coastal and open-ocean settings. Let's consider the usefulness of aquaculture for the environment and the security of food systems, as well as the costs involved.
1. Benefits of Coastal and Open-Ocean Aquaculture:
- Environmental Sustainability: Aquaculture can reduce overfishing and pressure on wild fish populations, helping to maintain biodiversity in oceans and coastal areas.
- Food Production: It provides a consistent and reliable source of seafood, which helps meet the growing demand for protein-rich food globally.
- Economic Growth: Aquaculture supports job creation and economic development, especially in coastal communities that rely on fishing and related industries.
2. Problems of Coastal and Open-Ocean Aquaculture:
- Environmental Impact: Concentrated fish waste, excess feed, and chemicals used in aquaculture can pollute the water, affecting local ecosystems. This pollution can harm wild fish and other marine organisms.
- Disease and Escapes: High-density fish farming can lead to the spread of diseases among farmed fish, which can then affect wild populations if fish escape from aquaculture facilities.
- Habitat Destruction: Coastal aquaculture, in particular, may require the conversion of natural habitats, such as mangroves or wetlands, into fish farms, resulting in the loss of valuable ecosystems.
Is Aquaculture a Useful Practice?
Aquaculture can be a useful practice for the environment and food systems, but it is important to address the associated challenges. The benefits of aquaculture, such as reduced pressure on wild fish stocks and economic growth, are significant. However, the negative impacts, including pollution and habitat destruction, need to be managed carefully to ensure the sustainability of aquaculture operations.
Differentiating Fish Farming and Filter Feeder (Mollusk) Farming:
Fish farming involves raising fish in tanks, cages, or ponds, while mollusk farming focuses on cultivating filter-feeding shellfish such as oysters and mussels.
Fish farming:
- Requires controlled feeding and management of fish species.
- Can be prone to disease outbreaks due to high stocking densities.
- May use artificial feeds that can contribute to pollution.
- Can have a higher environmental impact due to waste and escaped fish.
Mollusk farming:
- Relies on the natural filtration capabilities of bivalve shellfish to improve water quality.
- Typically has a lower environmental impact as bivalves consume natural plankton and improve water clarity.
- Can enhance local ecosystems by providing habitat for other organisms.
- Generally requires less feed and produces less waste than fish farming.

The mechanism by which the end product of a metabolic pathway inhibits an enzyme that catalyzes an earlier step in the pathway is most precisely described as Group of answer choices feedback inhibition cooperativity inhibition irreversible inhibition competitive inhibition
Answers
The mechanism by which the end product of a metabolic pathway inhibits an enzyme that catalyzes an earlier step in the pathway is most precisely described as feedback inhibition. The correct answer is option a.
Feedback inhibition is a regulatory mechanism that allows a cell to control the rate of a metabolic pathway by using the end product of the pathway as a signal to inhibit an earlier enzyme in the pathway. This inhibition reduces the rate of the pathway and prevents the accumulation of excess products.
Feedback inhibition is a type of reversible inhibition, which means that the inhibition can be relieved if the concentration of the end product decreases or if a different signal overrides the inhibition.
This is in contrast to irreversible inhibition, which permanently inactivates the enzyme, or competitive inhibition, which occurs when a molecule similar to the substrate binds to the active site of the enzyme and prevents the substrate from binding.
So, the correct answer is option a.

A B С D You are studying fish fossils in the sediment of an isolated lake in Canada. The strata are arranged (from top to bottom) as shown in the image above. However, you do not need the image to solve the problem. The strata and their fossils are arranged like this: You find numerous fish fossils from the same species in layers D, C, and A. The fish in layer A have long spines, those in layer C have medium-sized spines, and those in layer D have no spines. This fish species has not been found in other lakes, so you can safely assume no migration to or from the lake in the time period you are studying. Based on these fossil data, would you predict that the common ancestor of these lake fish: Had large spines Lacked spines Had medium spines
Answers
It is simpler to assume that the common ancestor did not have spines and that the spines evolved in different fish lineages, this conclusion is more likely to be correct.
Based on the fossil data presented in the problem, it can be predicted that the common ancestor of these lake fish lacked spines.
The answer to the question of what the common ancestor of these lake fish had can be answered by analyzing the fish fossils found in the sediment layers D, C, and A. The fish fossils from all three layers belong to the same species. The fish in layer A have long spines, those in layer C have medium-sized spines, and those in layer D have no spines.
Since the fish found in layer A have long spines and those in layer C have medium-sized spines, it can be assumed that these fish evolved from the fish found in layer D, which did not have spines. It can be concluded that the common ancestor of these lake fish lacked spines.
Explanation: The fact that the fish in layer D did not have spines indicates that the common ancestor did not have spines either.
This conclusion is based on the principle of parsimony, which assumes that the simplest explanation is usually the correct one. Since it is simpler to assume that the common ancestor did not have spines and that the spines evolved in different fish lineages, this conclusion is more likely to be correct.

Answers
Sex is a biological trait that refers to the observable physical and genetic characteristics that distinguish males from females. It is frequently assumed that sex is based on biological or genetic characteristics rather than social and cultural aspects.
The physical variations between males and females, such as genitalia and breasts, are some examples of sex differences. Thus, it is a biological characteristic rather than a social one. Both social constructionism and biological determinism, on the other hand, have opposing perspectives on gender. Biological determinism emphasizes that gender differences are inborn, while social constructionism emphasizes that they are socially produced. According to the social constructionism perspective, gender identity and the roles associated with it are the product of socialization and cultural expectations, whereas biological determinism focuses on innate biological differences and the impact of biology on gender.
The claim that sex is a biological trait and not socially constructed can be supported by two course materials. The article "Sex as Biological and Gender as a Social Construct" by Anne Fausto-Sterling argues that sex is a biological characteristic because it is based on genitalia and chromosomes, while gender is socially constructed. This article suggests that sex is primarily concerned with physical characteristics, while gender is linked to social and cultural expectations, which is consistent with the idea that sex is biological and gender is social.

A Frisbee is rolling smoothly down a hill with a rotational kinetic energy of 30 Joules. What is the most reasonable approximation for its translational kinetic energy
Answers
The Frisbee's translational kinetic energy is approximately 15 Joules.
To calculate the translational kinetic energy of the rolling Frisbee, we can use the concept of the parallel axis theorem, which states that the total kinetic energy of a rotating object is the sum of its rotational and translational kinetic energies.
Given:
Rotational kinetic energy (\(K_{rot}\)) = 30 Joules
The translational kinetic energy (\(K_{trans}\)) can be approximated by dividing the rotational kinetic energy by a factor of 2:
\(K_{trans}\) = \(K_{rot}\) / 2
= 30 Joules / 2
= 15 Joules
Therefore, the most reasonable approximation for Frisbee's translational kinetic energy is 15 Joules. This approximation assumes that the rolling motion of the Frisbee is smooth and there are no other significant factors affecting its energy distribution.

in using the muscle control formula, if the effect of the external force is in the same direction as the actual movement, what is the next thing to determine?
Answers
The movement's speed must be established. A step-by-step process for identifying the participating muscles and their action for any joint movement is provided by the muscle control formula that follows.
At first sight, this muscle control formula could seem a little difficult and complicated. But with some practise, you ought to be able to do it quickly. Once the technique is automatic and instinctual (after enough practise), you will be able to analyse movements without thinking about each step in the method. However, until you acquire these movement analysis instincts, using the muscle control formula is helpful. We state the issue before introducing the muscle control formula: Describe the name of the movement (or position), the plane of movement, the impact of the external force acting on the system, the type of muscle action (e.g., shortening or concentric, lengthening or eccentric, or isometric), and the muscles involved in the movement (or position), given a specific joint movement (or position).
