Overview â The distinctive tiger shark lives in both coastal and open seawaters, usually from the surface to around 459 feet. Young members of this species sport black stripes arranged over their otherwise gray backs and sides. These stripes can fade as the shark ages, making it look more like a great white than a tiger shark. Somehow it seems appropriate that this nocturnal, aggressive shark prefers dark, murky waters.
Obesity is one of the most important causes of bowel cancer [6, 9, 10]. Some groups have estimated that being overweight or obese causes about 11-14% of bowel cancer cases [10, 15, 17, 18]. Many large studies have found that bowel cancer is more common in overweight or obese people [7, 22-25].
SUMMARY: Science shows that genetics plays a role in obesity. Genes can directly cause obesity in disorders such as Bardet-Biedl syndrome and Prader-Willi syndrome. However genes do not always predict future health.Genes and behavior may both be needed for a person to be overweight.In some cases multiple genes may increase one s susceptibility for obesity and require outside factors; such as abundant food supply or little physical activity.owever genes do not always predict future health.
