1 Fragile X syndrome is a single gene disorder located on the X chromosome and is the leading inherited cause of intellectual disability. 2  Problems during pregnancy-Use of alcohol or drugs by the pregnant mother can cause intellectual disability. There are many genetic diseases associated with intellectual disability. 2  Some examples include PKU (phenylketonuria), a single gene disorder. 3  Due to a missing or defective enzyme, children with PKU cannot process a part of a protein called phenylalanine.
Potentially Hazardous Foods (PHFs): Potentially hazardous Foods (PHFs) are foods that require time and temperature control in order to prevent bacteria growth. The following are considered PHFs: Cooked or Raw Animal Products: Meat, fish, and poultry. Dairy products, including custard pies. Eggs (except for air-dried, hard boiled eggs with an intact shell)
This gradient is composed of both the pH gradient and the electrical gradient. The pH gradient is a result of the H+ ion concentration difference. Together the electrochemical gradient of protons is both a concentration and charge difference and is often called the proton motive force (PMF). In mitochondria the PMF is almost entirely made up of the electrical component but in chloroplasts the PMF is made up mostly of the pH gradient.
