It is a disorder that is caused by a microdeletion in chromosome band 22q11.2. The key gene that is lost is Tbx-1, a control gene that regulates other genes required for the connection of the heart with the blood circulation. Tbx-1 also controls genes involved in the development of the parathyroid and thymus glands and the shape of the face. Babies with DiGeorge syndrome are born with hypocalcemia, congenital heart disease, cleft lip and/or palate, and are highly susceptible to infections.
In this section, we examine how different scenarios affect your weight. 1  Mass & Distance affect the gravitational forces / attraction (aka-weight) between two objects. ï»¿ 2 Because you are made of matter, you exert gravitational fields. 3  Gravity is relatively a very weak force.
mass is the amount of matter in an object weight is a measure of the gravitational force exerted on an object gravity is a force of attraction between objects that is due to their masses, which decreases as the distance between the objects increases.ravity is the attraction between two or more masses. so any object always has mass. if the object is near something like a planet gravity effects it. which gives a fore on it, called weight.
