Flocculation â Towards the end of the fermentation process, individual yeast cells will clump together and sink to the bottom of the fermentation vessel. This process is called flocculation. Different strains of yeast contain different levels of âstickyâ carbohydrates on the surface of their cell walls. Because some have stickier cell walls than others, strains vary in the degree to which they flocculate and the manner in which they do so.
About 6 in 10 people with Marfan syndrome have dislocated lenses in one or both eyes. This means the lens, located at the front of the eye, has slipped out of place because the connective tissue that holds the lens in place (called zonules) is weak.
The cornea also plays a key role in vision by helping focus the light that comes into the eye. The cornea is responsible for 65Â­-75 percent of the eyeâs total focusing power. The cornea and lens of the eye are built to focus light on the retina, which is the light-sensitive tissue at the back of the eye. When light strikes the cornea, it bendsâor refractsâthe incoming light onto the lens. The lens refocuses that light onto the retina, which starts the translation of light into vision.
