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 human eye belongs to a general group of eyes found in nature called camera-type eyes.. Just as a camera lens focuses light onto film, a structure in the eye called the cornea focuses light onto a light-sensitive membrane called the retina.
