Answer:
can u maybe show a picture of the problem bc this makes it confusing if so ill edit my answer
Explanation:
The layer which protects the earth is referred to as magnetosphere.
Magnetosphere is termed as the region of space which surrounds astronomical object by way of magnetic fields.
They create planets which generates planets in magnetic field which include fields where they can occur in stars through interaction of plasma.
Magnetosphere blows away particles from the earth and also from the sun.
Coal results from the compressed remains of plant matter, while natural gas is the compressed remains of marine organisms. Natural gas was made due to pressure and heat under buried layers of rock over millions of years, while coal was made by heating the compressed remains from magma underneath.

When she plays football, she uses more energy than usual.
Some of her body systems work faster than normal.
Task:
Describe what happens to her circulation system and her breathing
system when she plays football. Explain why these changes happen.
Draw diagrams to help explain your ideas.
Keywords to include: respiration, heart, lungs, oxygen, carbon dioxide,
alveoli, inhalation, exhalation, diffusion, red blood cells (13 marks)
Answer:
Firstly, when we exercise, or do some activity (in this case football), we use more energy than usual...
The reason some of her body systems work faster than normal, is to keep the body working and in the equilibrium, so that she won’t get tired too fast.
Related to circulation, her blood flow increases, since she needs more oxygen to reach the muscles faster, due to the exercise/activity (Lactic acid builds up, so more oxygen is required.)
Her breathing increases to take in more oxygen(O2), and give out more carbon dioxide(CO2).
Her body respires more(respiration), both aerobically(with oxygen), and anaerobically(without oxygen), lactic acid builds up due to anaerobic respiration.
(Here, energy is released from glucose to generate a substance called lactic acid. ... Therefore anaerobic respiration cannot be used for a prolonged period of time without having damaging effects on a cell.)
When she inhales (Oxygen), it goes to the lungs, to the alveoli ( Alveoli are tiny air sacs in your lungs that take up the oxygen you breathe in and keep your body going)
In the Alveoli, diffusion takes place, this is where oxygen is diffused into the blood, and carbon dioxide is diffused (taken into) into the lungs.
Then we exhale, which gives out the carbon dioxide(CO2), this happens really fast, we also breathe so fast, this process happens within seconds.
Red blood cells contain something called haemoglobin, this combines with oxygen To form oxyhaemoglobin, then when the red blood cell reaches the muscle, it gives the oxygen, converting oxyhaemoglobin back to haemoglobin.
Heart: pumps blood faster (as I said before), to ensure oxygen gets distributed faster to where it’s needed
