Helium is not important for living beings.
It can be, but usually not. Helium is a bit expensive, and it'd cost too much for most balloonists to use it. It's cheaper to use a hot air balloon. helium is lighter than air. hence balloons filled will helium will float in air.
Speed is not determined by the composition of a gas. Too may other variables. As phrased, there is no answer possible to your question. Will helium seep out of a balloon faster than air? Yes. Go faster? Explain your question.
Helium is a gas used to inflate lighter than air balloons.
A little helium isn't harmful, but inhaling an entire balloon-full can block oxygen to your brain, which might cause you to pass out. There has been at least one death from breathing helium from a pressurized tank instead of a balloon, too.
Helium is safer than hydrogen in hot air balloons because it is non-flammable. Hydrogen can ignite easily, posing a greater risk of fire. Additionally, helium is more stable and its lifting capacity is sufficient for use in hot air balloons.

Hot air balloons use hot air. They have a burner to heat the air. Hydrogen balloons were too dangerous because hydrogen is highly flammable, even static electricity could cause an explosion. Helium is safer because helium is not flammable.
if there too little water animal die crops are not growing and if their is too much water flood came
When you inhale helium, your voice may sound higher-pitched because helium is less dense than the air in your lungs, causing the speed of sound to increase. However, inhaling too much helium can be dangerous as it can displace oxygen in your lungs, leading to difficulty breathing and potentially harmful side effects. It is not recommended to inhale helium for fun or as a prank.
You die

it can have effects on your memory
Too little cholesterol level IS dangerous in its effect on hormone secretions.
No, it wouldn't work the matteral is too heavy
Original answer: "voice go up high..... i think that is it..."People should not answer questions if they are too ignorant or bigoted to do so properly.Inhaling Helium is always a risk. When helium is inhaled, it takes up space in the lungs that air (nitrogen, oxygen, et cetera) should occupy. This will lead to suffocation if the helium is not quickly pumped from the lungs by breathing air for several minutes. Too much helium is bad for you, because not all air is removed from the lungs in one breath. Therefore, repeatedly breathing helium will make you short of breath, effectly suffocating you over time. This does not always result in death.
