Oxygen is necessary for human survival as we need it to breathe and for our cells to function. However, exposure to extremely high levels of oxygen can be harmful and cause oxygen toxicity. This is rare and usually only occurs in situations like medical treatment with high levels of supplemental oxygen.
Mountain climbers need oxygen masks at high altitudes because the air becomes thinner and contains less oxygen, leading to hypoxia which can result in dizziness, shortness of breath, confusion, and even death. Oxygen masks help climbers supplement the oxygen they need to maintain proper breathing and prevent altitude sickness.
No. Earth's oxygen is provided by plants. Humans need oxygen to live, so we could not have been there before there was oxygen, so we could not have made the oxygen.
Hemoglobin, a protein found in red blood cells, carries oxygen in the blood. It has a high affinity for oxygen, allowing it to bind to oxygen molecules in the lungs and release them to the body tissues that need oxygen for cellular respiration.
The distance you can go before running out of oxygen depends on factors like your level of physical activity and the volume of oxygen in your tank. On average, a scuba diver with a standard tank can go from 30 minutes to an hour at recreational depths before running out of oxygen. It is essential to monitor your oxygen levels and plan your dive accordingly.
How to get there and how high you can go before needing oxygen.
As the balloon ascends into the atmosphere, the air pressure surrounding it decreases, causing the gas inside the balloon to expand. Eventually, the gas inside the balloon will expand so much that the balloon will burst or pop. Pieces of the balloon will then fall back down to the ground.
Oxygen absorbers typically last about 1-2 years before they need to be replaced.
High altitude animals need a high affinity for oxygen to effectively extract the limited oxygen available in their environment, where atmospheric pressure is lower, resulting in reduced oxygen levels. This adaptation allows them to efficiently bind and transport oxygen from the lungs to their tissues, ensuring that vital metabolic processes continue despite the challenging conditions. Additionally, a high affinity for oxygen helps maintain energy production and overall physiological function in the harsh, hypoxic conditions of high altitudes.
Hot air balloons typically do not require supplemental oxygen until altitudes of around 10,000 feet (3,048 meters). At this elevation, the air density decreases significantly, which can lead to reduced oxygen levels. Pilots may choose to fly higher, but they should be aware of the potential for hypoxia and the need for oxygen systems if exceeding this altitude. Safety regulations and personal comfort levels will also dictate altitude limits for balloon flights.
Usually fish need high oxygen levels. Sure they live in water, however they often hide near rocks and corals, places were they are able to get alternating levels of oxygen. Some creatures live near underwater volcanoes where the temperature and oxygen levels are altered. Other fish need to surface to the water in order to capture a breath of air before they dive down into the water again. Some fish species who are unable to collect water can drown from suffocation when unable to get enough oxygen.
Because of high altitude sickness which is affected by climbing up high were there is high altitude. High altitude is were there is to much oxygen up high, if you breech in to much oxygen you could faint.
You need a balloon, flour and a funnel. All you need to do is put the funnel inside the balloon and pour the flour in. When it is big enough you can tie the balloon up and put googly eyes on it.
Typically, the minimum amount of PSI recommended in an oxygen tank before needing to be exchanged is around 500 PSI. This ensures that there is enough oxygen for safe use and prevents running out unexpectedly.
No you need a special type of balloon.
A banana will slowly inflate a sealed balloon or plastic bag because it gives off gases (notably ethylene) as it ripens. However, if a banana is too ripe, it may oxidize and remove oxygen from the air.
No, air pressure increases as the balloon goes up, so the balloon will pop and fall to the ground. You can get high up in the atmosphere (but you need a LOT of helium and a balloon that can get VERY big) you will not reach "outer" space beyond the Earth's atmosphere.
