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.
Credit: koya979 Shutterstock. Gravity is the force that attracts two bodies toward each other, the force that causes apples to fall toward the ground and the planets to orbit the sun. The more massive an object is, the stronger its gravitational pull. Fundamental force. Gravity is one of the four fundamental forces, along with the electromagnetic, strong and weak forces. It is what causes objects to have weight. When you weigh yourself, the scale tells you how much gravity is acting on your body. The formula for determining weight is: weight equals mass times gravity. On Earth, gravity is a constant 9.8 meters per second squared, or 9.8 m/s 2.
