Which organ in the fish is most similar to the human respiratory system? The Alternative Lung In a way, the Fish Respiratory system is similar to the human respiratory system. However, at the same time it is not. Fishes breathe through their gills, taking in dissolved oxygen and carbon dioxide. Their lungs(gills) are placed toward […]

Why do solids do not diffuse in each other? This is because of diffusion , the movement of particles from an area of high concentration to an area of low concentration. This means that diffusion does not happen in solids – the particles in a solid can only vibrate and cannot move from place to […]

What will happen if a spaceship that is motionless in deep space is given a quick push? What will happen if a spacecraft that seems to be motionless in deep space is given some type of quick push? The spacecraft will move and will not stop until it is stopped by an equal and opposite […]

How do humans do photosynthesis? Human photosynthesis doesn’t exist; we must farm, slaughter, cook, chew and digest — efforts that require time and calories to accomplish. As the human population grows, so does the demand for agricultural goods. Not only are our bodies expending energy, but so are the farm machines we use to make […]

What is the main cause of food waste? What causes food loss and waste? Food loss occurs for many reasons, with some types of loss—such as spoilage—occurring at every stage of the production and supply chain. At the retail level, equipment malfunction (such as faulty cold storage), over-ordering, and culling of blemished produce can result […]

What are the two characteristics of an atom? Atoms are the smallest fraction of an element that can exist, and still show the characteristics of the element. Atoms themselves are composed essentially of electrons (1 negative charge), protons (1 positive charge), and neutrons (no charge). Why does each atom have specific properties? The difference in […]

What are the examples of positive feedback mechanism? The release of oxytocin from the posterior pituitary gland during labor is an example of positive feedback mechanism. Oxytocin stimulates the muscle contractions that push the baby through the birth canal. The release of oxytocin result in stronger or augmented contractions during labor. What are examples of […]

What do you do if more light is needed to view the specimen? Describe what to do if more light is needed to view the specimen. The objective lens can be used to increase light, and the focus knob can be adjusted as well. What determines how much light shines on the specimen? The diaphragm […]

What is the main role of operating system? An operating system is the most important software that runs on a computer. It manages the computer’s memory and processes, as well as all of its software and hardware. It also allows you to communicate with the computer without knowing how to speak the computer’s language. What […]

At what speed do airbags deploy KMS? In reality, they’re rock hard, the airbag deployment speed can reach 300 km/h or more, and it all happens in a fraction of a second. They’re meant to prevent your head from striking the steering wheel, dash, windshield or side window. How long does it take an airbag […]
