What is an experimental control example?

What is an experimental control example? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. Why is it important to have […]

Where is the lithosphere?

Where is the lithosphere? The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. What are the two main […]

What happens when electrons get excited?

What happens when electrons get excited? When an atom is in an excited state, the electron can drop all the way to the ground state in one go, or stop on the way in an intermediate level. Electrons do not stay in excited states for very long – they soon return to their ground states, […]

How do you overcome lack of physical activity?

How do you overcome lack of physical activity? Social support Explain your interest in physical activity to friends and family. Ask them to support your efforts. Invite friends and family members to exercise with you. Plan social activities involving exercise. Develop new friendships with physically active people. What physical activity is the least expensive? Walking […]

What should oxygen and acetylene be set at?

What should oxygen and acetylene be set at? In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size. Simply adjust them until you get a neutral flame, but pay close attention to the acetylene pressure to prevent it […]

What happens if you block potassium channels?

What happens if you block potassium channels? Activation leads to an increase in conductance and the termination of action potentials, hyperpolarization, and a reduction in excitability. Conversely, a block of the channels leads to depolarization, prolongation of action potentials, repetitive firing, and increases in transmitter release and endocrine activity. What happens if potassium leak channels […]
