All nutrients are vital... so you can't say that Iron is more important than Proteins or Proteins are more important than Potassium. so that's why we have made a balanced diet so that we can remain healthy. And it has been said "Excess in quantity is bad and so is it bad when there is scarcity of something!"
you will get dihydrated or you wont live scientific studys show you cant live without water only food
You can't. They can only be downloaded from Xbox LIVE.
You can. You won't be able to very physically active, but people have survived with only one lung.
No they cannot live without blood; they will die within 1-2 days without it.
By only spending on what you cant do without
because they cant live longer...duhhh
No, a person cannot live without their lungs.
they can't live on land because they need to grow in water
beetles cant live months they only can live for 2 or 1 weeks
No , you cant live without a heart. The heart is reasonable for circulating the blood around the body. Blood carries the oxygen, which the body needs to survive. The only exception to this is someone had a artificial heart, it would be doing the same work as a human heart.
Food is not only a nutrient, but rather several nutrients. Food is a required thing that humans need in order to survive. Without nutrients, the body would not function.
Different body processes require different nutrients. But the catch-all would have to be water.Water is the one thing we can't do without. We can live for about a month without food, (no calories, no vitamins, nothing) but only a week, maximum, without water.
