What system uses oxygen for energy? Aerobic Glycolysis How does oxygen create energy? Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. When the cell uses oxygen to break down sugar, […]
What law is the reason why we balance chemical equations?
What law is the reason why we balance chemical equations? Re: Why do we balance chemical equations? We balance chemical equations due to the law of conservation of mass, which states that mass can neither be created or destroyed. Therefore, in a chemical reaction, the total mass of the reactants must be equal to the […]
Does equilibrium constant depend on pressure?
Does equilibrium constant depend on pressure? Equilibrium constants are not changed if you change the pressure of the system. The only thing that changes an equilibrium constant is a change of temperature. If there are the same number of molecules on each side of the equation, then a change of pressure makes no difference to […]
Which system of Signalling is used on a single line?

What are the processes of physical and chemical weathering?
What are the processes of physical and chemical weathering? Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, rapid heating/cooling, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it […]
How dangerous is the luge?
How dangerous is the luge? With speeds up to 90 mph, luge is one of the most dangerous sports in the Olympic Games. Luge is similar to skeleton but with athletes sliding down with their face up and feet first. This high-speed sport requires good upper-body strength and efficient navigation of the course. What is […]
Which of the following is an example of oxidation?
Which of the following is an example of oxidation? Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. What are three […]
Is aluminum hard to machine?
Is aluminum hard to machine? Fortunately, compared with other construction materials, aluminum is relatively easy to machine. It responds well to most fabrication methods, including milling, drilling, cutting, punching and bending. What is the lowest grade of aluminum? Grade 1050 aluminium Is aluminum toxic to the human body? Oral exposure to aluminum is usually not […]
What are the sensory receptors?
What are the sensory receptors? Sensory receptors are dendrites of sensory neurons specialized for receiving specific kinds of stimuli. Sense organs (such as the eyes and ears) consist of sensory neurons with receptors for the special senses (vision, hearing, smell, taste, and equilibrium) together with connective, epithelial, or other tissues. What are the 6 sensory […]
