What is the correct way to breathe?
What is the correct way to breathe? The most efficient way to breathe is by bringing the air down toward the belly. As the diaphragm contracts, the belly expands to fill the lungs with air. “Belly breathing” is efficient because it pulls the lungs downward, creating negative pressure inside the chest. Is mouth breathing bad? […]

Why do trains have 2 locomotives?
Why do trains have 2 locomotives? The simple reason is that by having two locomotives, the train can move in both directions – which is ideal if the train needs to reverse at any point (for example, and usually, at a terminus station, where there is a buffer/stop at the end of the platform). Why […]
What happens when light hits a rod cell?
What happens when light hits a rod cell? When light hits photoreceptive pigments within the photoreceptor cell, the pigment changes shape. The retinal exists in the 11-cis-retinal form when in the dark, and stimulation by light causes its structure to change to all-trans-retinal. How does a rod cell work? Rod cells are stimulated by light […]
