Answer: trachea
Explanation:
During inhalation, air moves from the larynx into the trachea. Air enters the oral cavity, and then it moves into the pharynx.
Oxygen used in cellular respiration ends up in ATP Synthesis in Oxidative Phosphorylation.
Explanation:
Since oxygen is the last electron acceptor in Electron transfer chain, the H ions flow through ATP synthase for ATP synthesis. The electrons from the NADH and FADH are pumped from the matrix of mitochondria to inter-membrane space. The energy released due to the proton gradient formed is used for making ATP.

Rewrite the sentences:
1. all matter is made up of tiny particles calles atoms and molecules
2. right
3. right
4. compounds are chemically joined together
task 2:
1. i know this is element
2. i know this is compound
3. i know this is mixture
task 3:
In this lesson i have learned that Atoms are in everything and are what makes up most of the stuff on earth. They are tiny molecules that make up me and everything around me. I have also learned that atoms are made up of Elements. Elements are chemical molecules that make up things like the air we breathe. However, when more than one element joins together a compound is formed. Compounds make up more physical things around me such as drinking water and salt for cooking. When many different compounds are joined together a mixture is formed. An example of a mixture can be sand and water.
Explanation:
