The brain and spinal cord make up the central nervous system.
The food chain is very important to ecosystems.
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.
Excretory system and urinary system are both working to remove waste in the human body. but technically, urinary system is part of the excretory system. The excretory system includes the kidney organ which is the main and the most important organ of the urinary system, another part of the excretory systems are the large intestine and the lungs. on the other hand, urinary system aside from kidney includes ureters, urinary bladder and the urethra. when the human body produces waste products, both the excretory and the urinary work together to remove these waste products from the human body.
Hello There!
It contains dissolved substances, cells and cell fragments.
The other parts of blood are:
Red blood cells - Carry blood around the body
White blood bells - Fight against bacteria and diseases
Platelets - Small fragments of bells. They are involved in forming blood clots.
Hope This Helps You!
Good Luck :)
