Ok idk if there was a picture that was supposed to go with that cause I don't see one but here are some vestigial structures in humans: Appendix, Pinky toe (debatable possible used for balance) , ear muscles, tail bone, wisdom teeth, nictitating membrane, male nipples (sorry to be gross), and goosebumps. Those are the ones I can remember. Hope this helps!
Answer:
6 carbon dioxide molecules
Answer:
the proton and the neutron
Explanation:
An atom is made up of subatomic particles; neutrons, protons and electrons. The protons are positively charged subatomic particles found in the nucleus with a mass equal to 1.6 \times 10^{-27} kg. The electrons are negatively charged particles of an atom found in the orbital shells in constant motion. They have a mass equal to 9.1 \times 10^{-31} kg. The neutrons are particles found in the nucleus that have no charge and have a mass equal to 1.6 \times 10^{-27} kg. therefore protons and neutrons are similar in mass.
Breathing in
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
