Mass is constant and does not depend on gravity, Where As <span>Weight is the force something exerts from its acceleration due to gravity.
Example: </span>A 100 g sample is 100 g on the earth, on the moon, wherever. <span>Since the force of gravity varies, this amount can vary greatly depending on where the thing was weighed. Even on earth the difference in the force of gravity between different elevations is sufficient for an object's weight to be different.</span>
Answer:
Arteries carry blood away from the heart; veins carry blood back to the heart.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
Diastole: in this stage, the ventricles is relaxed and would be filled with blood.
Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The best description for arteries and veins is that arteries carry oxygenated blood away from the heart to other parts of the body such as brain, lungs, tissues, etc; veins carry blood that is low in oxygen content back to the heart.

The answer to your question is true
Kübler-Ross was a psychiatrist who studied how we people deal with sorrow (after losing beloved ones, by knowing that we are ill or that we are going to die, etc.). There are five stages which people in this situation normally experience (but not obligatory):
(1) DENIAL
This is the first phase. It is filled with strong emotions and the dominant one is the shock and, after that, denying. Acknowledging tragic events and facts is very disturbing for our mind and it tries to protect itself.
(2) ANGER
Although we can be denying certain things for a long time, in the end, we realize that it won't help and things won't change. In this stage, our minds and our body respond with fury. Individuals tend to think that it is unfair that it happens to them.
(3) BARGAINING
In this phase, a person will desperately try to "negotiate" with the aim to change the outcome. We start to regret the things we did or didn't do earlier, we are ready to do anything and bear anything, just to make the things right.
(4) DEPRESSION
For the first time, we actually see the present moment and we feel all the grief we have been trying to deny or fight. A person is tired of the battle from the three previous stages and we assume our sorrow. It results in a depression, but this is a normal reaction in this kind of situation.
(5) ACCEPTANCE
Finally, after all the stages one has been through, he/she acknowledges reality. We accept the things as they are and we learn to live with them. It doesn't mean that we stop being sad, we have just passed through all the process and our life continues.
