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.
On Earth, any object that has mass has gravitational pull; this is called force. Gravitational forces are forces of attraction. The strength of the gravitational force depends on the mass of the object and its proximity to the Earth. The larger and closer the object, the greater the gravitational pull. Gravitational force on the Earth cause objects to accelerate when they fall. The Earthâs gravity produces the same amount of acceleration on all objects, and they gain velocity at the same rate. Gravity pulls the objects toward the Earth, and they speed up as they get closer to the Earth.
