When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.
Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.
Hope this helped, even if it helped a tiny bit. :)

The sky on Earth is blue because blue light is scattered through the atmosphere as the other colors of light pass through undisturbed. Which nebulae have something similar going on?
Answer:
Yes
Explanation:
Reflection nebulae mostly appear to have a blue colour. This is because particles in the nebula scatter (or reflect) blue light more efficiently than they scatter red light. The same effect is responsible for our sky being blue, not red, during the daytime.

what makes mining possible in continental crust? 2-3sentences science
Answer:
Due to softer materials.
Explanation:
Lighter materials of the crust made mining possible in continental crust because the materials present in the upper part of the crust are softer and lighter as compared to lower part. When the earth surface cools down, the lighter materials moves upward while denser materials remains in the center so that's why mining can be done in the continental crust due to its softer nature.

what do electrons in the same shell have in common
Answer:It predicts and lists all chemical elements in the universe. What do electrons in the same shell have in common? They all have the same amount of energy. ... They cannot be broken apart without losing their chemical properties.
Explanation:I took a quiz on it
Electrons in the same shell, also known as the same energy level or principal quantum number, have energy, shielding effect, chemical behavior, etc. in common.
Electrons in the same shell have approximately the same energy level. The energy of an electron is determined by its distance from the nucleus, and electrons in the same shell are at a similar average distance from the nucleus.
Electrons in the same shell shield each other from the positive charge of the nucleus. This shielding effect reduces the attraction between the positively charged nucleus and the negatively charged electrons in the outer shells.
Electrons in the same shell participate in similar chemical reactions and exhibit similar chemical behavior.
Electrons in the same shell occupy orbitals with similar shapes. Each shell contains one or more subshells, which consist of specific orbitals that can accommodate electrons.
Thus, these are the properties of electrons in same shell.
