Atoms accumulate on crystal faces during mineral growth. This is significant in the organization of crystals where atoms, ions, or molecules are arranged in a certain pattern. This principle can be seen in different types of crystalline structures including metal crystals and silicate minerals.

During any type of mineral growth, atoms accumulate on D. crystal faces. In the process of crystallization, atoms, ions, or molecules are arranged in a repeating pattern on the crystal faces. When we consider a substance formed of crystals with equal numbers of cations and anions held together by ionic bonds, we can visualize this arrangement.

Many metals crystallize in an arrangement known as face-centered cubic (FCC) solid. The FCC unit cell contains atoms positioned at all corners and at the centers of each face, resulting in atoms collecting on the crystal faces.

When defects occur in the crystalline solid, atoms or ions might occupy different positions, causing distortions. This concept can be broadened to the formation of mineral crystals such as silicates, where silicon and oxygen atoms collect on crystal faces.

Final answer:

In the human respiratory system, the nasal cavity functions similarly to a humidifier by warming and humidifying air as it passes through, thus helping to protect the respiratory tract.

Explanation:

A humidifier adds moisture to dry air, which can be particularly soothing for someone with a respiratory system infection, like bronchitis. In the human respiratory system, the nasal cavity performs a similar function. As air passes through the nasal cavity, it is warmed and humidified by the moisture from mucous membranes. This air modification protects the respiratory tract by sealing the tissues from direct contact with air and prevents potential damage from cold, dry air. Furthermore, the mucus in the respiratory tract, which is high in water content, helps to humidify and pick up water as air crosses these mucous surfaces, ensuring the air equilibrates to body conditions.

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.The third law states that for every action (force) in nature there is an equal and opposite reaction.

Final answer:

Newton's three laws of motion describe how objects behave when forces act upon them. The first law states that objects at rest stay at rest and objects in motion continue in motion unless acted upon by an outside force. The second law relates force, mass, and acceleration. The third law states that for every action, there is an equal and opposite reaction.

Explanation:

Newtons's First Law:
Newton's first law states that every object will continue to be in a state of rest or move at a constant speed in a straight line unless it is compelled to change by an outside force. For example, if a book is sitting on a table, it will remain at rest until a force, such as someone pushing it, is applied to make it move.

Newton's Second Law:
Newton's second law states that the change of motion of a body is proportional to and in the direction of the force acting on it. This means that when a force is applied to an object, its acceleration is directly proportional to the force and inversely proportional to its mass. For example, if you push a small toy car with a large force, it will accelerate quickly because the mass of the car is small.

Newton's Third Law:
Newton's third law states that for every action, there is an equal and opposite reaction. This means that when one object exerts a force on another object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. For example, when you push against a wall, the wall pushes back with an equal force, keeping you from falling through it.

Answer:The Central Nervous System sends signals to the rest of the body and activates external and internal stimuli.

Explanation:The CNS is made up of the brain and spinal chord which send signals to the body. In addition, it controls simple musculoskeletal reflexes.

The main function of the central nervous system is to process information and coordinate the activity of all parts of the body.

The central nervous system (CNS) is composed of the brain and spinal cord, and it serves as the control center for the entire nervous system. Its primary roles include:

1. Information Processing: The CNS receives sensory input from all over the body, processes this information, and then decides on the appropriate response. This involves interpreting signals from sensory receptors, integrating these signals, and determining the necessary actions.

2. Coordination: The CNS coordinates voluntary movements, such as walking and talking, as well as involuntary actions, like breathing and maintaining heart rate. It does this by sending out motor commands to the muscles and glands.

3. Regulation: The CNS helps regulate many of the body's functions, including homeostasis, which is the maintenance of a stable internal environment despite changes in external conditions.

4. Learning and Memory: The brain, a part of the CNS, is responsible for cognitive functions such as learning, memory, problem-solving, and decision-making.

5. Emotional Processing: The CNS also processes emotions and is involved in the perception and expression of feelings.

In summary, the central nervous system's main function is to integrate all incoming and outgoing information, analyze the information, and coordinate the activity of the body's various systems to maintain health and homeostasis. It is the center of consciousness and the primary organizer of all behavior, both voluntary and involuntary.

People who exercise need more calories because physical activity increases their energy expenditure. Exercise burns calories during the activity and raises the basal metabolic rate (BMR), resulting in a higher overall calorie requirement. Athletes, in particular, have increased energy needs due to the intensity and frequency of their exercise.

When you exercise, your body requires more energy to support the physical activity. This increased energy requirement is met by burning calories. When you burn calories, you are using stored energy from your body, particularly from fat reserves. Therefore, people who exercise need more calories to replenish the energy they have expended during physical activity.

Exercise not only burns calories during the activity itself but also increases your basal metabolic rate (BMR). BMR is the number of calories your body needs to perform its basic functions, such as breathing and circulating blood, while at rest. When you exercise regularly, your BMR increases, leading to a higher overall calorie requirement.

For example, a competitive athlete may need 3,000 to over 5,000 calories daily, compared to a sedentary individual who needs about 2,000 calories per day. The energy needs of athletes are influenced by factors such as the intensity, duration, and frequency of their exercise, as well as their gender, age, and weight.
