Answer:
All systems work together to stabilize the body.
Explanation:
Certain systems work with each other in order to maintain homeostasis, which is essential for the body. For example, when blood circulates through the digestive system, it picks up nutrients absorbed by the body during its last meal. Additionally, blood carries oxygen taken in by the lungs. The circulatory system works with the respiratory system here to distribute oxygen to other parts of the body.
This can be answered by asking why do we all have different skin colours: Melanin pigmentation. Years of evolution made different people around the worrld different skin colours as an protective mechanism against high levels of UVR exposure, the closer people were to the eqautor, the hotter it would be, so many people living in tropical and desert like climates had darker skin. To answer about folate though, people are darker skin tones living near the equator had dark skin to prevent folate deficiency. So yes everyone has folate, but some people are darker skin to better protect it and their skin.
Hope this helps, HAVE A BLESSED AND WONDERFUL DAY! As well as a great Superbowl Weekend! :-)

Different parts of the sun lit moon become visible as the moon revolves around earth
This happens because as the moon orbits earth the sun will project light towards it and the reason it seems to glow is because of the reflected light since the moon is white it reflects more light. Think of it as a day and night cycle except it’s on the moon when it becomes night on earth the part of earth facing towards the sun will be lit aka day/morning/afternoon etc
The part of the earth facing away will be dark aka night/midnight/etc.
