Is the ability of the heart lungs and blood vessels to deliver oxygen to your body tissues? Cardiovascular endurance is the ability of the heart, lungs and blood vessels to deliver oxygen to working muscles and tissues, as well as the ability of those muscles and tissues to utilize that oxygen over an extended period […]
What are 4 ways the periodic table is organized?
What are 4 ways the periodic table is organized? The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. What are the rows on the […]
What is critical period in development?
What is critical period in development? What is the critical period? Also known as the sensitive period, the critical period is a time during early postnatal life when the development and maturation of functional properties of the brain, its ‘plasticity’, is strongly dependent on experience or environmental influences. What are the five main areas of […]
What is the relationship between S and P waves?
What is the relationship between S and P waves? P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives […]

What happens to the molecules of water when it freezes?
What happens to the molecules of water when it freezes? Point out that when water freezes, the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were in liquid water. Note: The molecules in ice […]
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 […]
What do you notice about the iron filings?
What do you notice about the iron filings? All magnets show properties of magnetic attraction and repulsion. With the use of iron filings, we can see these magnetic fields. When iron filings are sprinkled on a bar magnet, you see that these magnetic field lines start at the magnet’s north end and will end at […]
