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.
Gravity is the force of attraction between all masses. Although gravity is said to be exerted by everything that has a mass, only those objects with very large masses actually affect anything near them. A gravitational field is the area around the body that is exerting the gravitational pull.It can be defined as the gravitational force felt by a unit's mass placed at a point in space. Gravity has three very important effects. First, it makes all things accelerate towards it.ravity is the force of attraction between all masses. Although gravity is said to be exerted by everything that has a mass, only those objects with very large masses actually affect anything near them.
