Traits are determined by DNA. Small segments of DNA are called genes. These genes instruct for a certain protein to be made. Those proteins give us our traits. Hope that helps!
Okay, so this is physics. What is the meaning of KE? It's Kinetic Energy. What is the meaning of GPE? It's Gravitational Potential Energy. So how do you calculate either, and what are their significances? Kinetic -> motion, Gravitational potential energy -> energy that can be used to do work due to gravity. So is the bowling ball moving, or is it someplace it can fall from, or both?
Kinetic energy is calculated as 1/2 * mv^2, where m is the mass of the object, and v is the velocity. Potential energy for conservative forces is the product of the force and the distance over which it can do work. Thus in the case of GPE, it is the weight multiplied by the height, as gravity is a conservative force. What is the weight? It's not equal to the mass.
Hopefully these hints will get you thinking.
Answer:
Explanation:
In the process of differentiation the stem cells develop different sub-cellular structures to turn into the different types of cells - specialisation. The specialised cells can now carry out their important specific functions - essential for the efficient and healthy viability of any organism.
