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.
The force of gravity is the force exerted by the gravitational field of a massive object on any body within the vicinity of its surface.This force is dependent on three factors: the mass of the massive object, the mass of the smaller body, and the separation between the two, measured between their geometrical centers. 1 = mass of the first object (lets assume itâs of the massive one). m 2 = mass of the second object (lets assume itâs of the smaller one). r = the separation between the two masses. Notice that the gravitational force is directly proportional to m 1.
