What is an atom made of?

They’re typically made up of three main parts: protons, neutrons and electrons. Think of the protons and neutrons as together forming a “sun”, or nucleus, at the centre of the system.

How much oxygen is in our water?

These are found in beetroot, garlic, leafy greens, pomegranate, cruciferous vegetables, sprouts, meat, nuts, and seeds.

Why is my oxygen saturation low?

Some of the most common causes of hypoxemia include: Heart conditions, including heart defects. Lung conditions such as asthma, emphysema, and bronchitis. Locations of high altitudes, where oxygen in the air is lower.

Does your oxygen level drop when flying?

The air on a plane contains less oxygen than the air we normally breathe in. This leads to lower levels of oxygen in the blood. If you do not have a lung condition, the drop in oxygen is not enough that you would feel the difference.
