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 most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation. What this means is that for any two objects in the universe, the gravity between these two objects depends only on their mass and distance.
