Answer:
Proteins contain the elements carbon, hydrogen, and oxygen just as carbohydrates and lipids do, but proteins are the only macronutrient that contains nitrogen. In each amino acid the elements are arranged into a specific conformation around a carbon center.
Gravity is a force of attraction and friction is a force of opposing motion.
<u>Explanation:</u>
When an object is subjected to a push or a pull then it is called as force. The Newton is the unit of force and when all the forces that are acting on an object is integrated it gives to the Net force. When two objects contacts each other there exits friction. It is the force that is responsible in opposing the motion of the objects as they contact each other.
The force that is attractive and results in pulling of the objects is Gravity. The attraction that exists between two objects is because of the mass. The acceleration that is being induced in an object that is in movement with the gravitational force is called as acceleration due to gravity.
Answer:
Homeostasis is the maintenance of a stable internal environment. Homeostasis is a term coined to describe the physical and chemical parameters that an organism must maintain to allow proper functioning of its component cells, tissues, organs, and organ systems.
