Scientists establish the age of a rock or fossil based on natural radioactive decay and certain elements such as potassium and carbon, this is used to make reliable “clocks” to date ancient events.
(Sorry if not all is accurate hope it helps)
Answer:
Bronchioles
Explanation:
You inhale through your nose and the air is filtered. It goes down the pharynx. It goes through the larynx. A "door" called the epiglottis opens during breathing. Then it enters the trachea. (windpipe) It goes through the bronchus. The tertiary bronchi branch into fine tubules called bronchioles, the last passageways for air. Air ends its pathway in the ________. (I bet you can guess because you're so smart!) They're surrounded by capillaries that connect the pulmonary arteries and veins. This enables the transfer of oxygen and carbon dioxide.
I hope this helped!!! Good luck on the test/quiz/project/homework/etc. you're working on! If you want I can give you a l!nk to the article I used. If not, it's fine too. Have a great day!
The equation for photosynthesis is given as:
6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂
<h3>Photosynthesis</h3>
Photosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.
Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.
During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.
The equation for photosynthesis is given as:
6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂

Would the answer be estrogen? I'm not completely sure.
Answer:
The correct answer will be- primary motor cortex
Explanation:
The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain. The motor cortex is thought to be involved in the planning actions and control voluntary actions.
The motor cortex is divided into three regions: premotor cortex, primary motor cortex and supplementary motor area.
The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.
Thus, the primary motor cortex is the correct answer.
