Problem: Process: - Air enters the lungs through bronchial tubes - Air enters bronchioles - Bronchioles have tiny air sacs called alveoli - Alveoli surrounded by small blood vessels - Oxygen absorbed by small blood vessels - Vessels deliver oxygen to every cell in the body - Blood brings carbon dioxide back to lungs - Carbon dioxide released when you exhale.  Question: suppose pure oxygen is breathed for medical purposes happens, how will it affect a SMALLER amount of oxygen being delivered to the blood stream.  - A: more - B: less - C: no effect

A: B


Problem: Process: - The diaphragm contracts - The lungs expand - Air is pulled from outside the body, into the lungs - The membranes in the lungs collect oxygen molecules - Oxygen is transferred to red blood cells - Red blood cells distribute oxygen throughout the body -   Question: suppose a person attends more parties happens, how will it affect the lungs expand less.  - A: more - B: less - C: no effect

A: C


Problem: Process: - A photovoltaic cell is created with two layers of semiconductor material - The top layer are &#x27;doped&#x27; with impurities to allow a negative charge - The bottom layer are &#x27;doped&#x27; to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue - Give the cells owner a flow of electricity.  Question: suppose less virus exposure happens, how will it affect LESS solar power being generated.  - A: more - B: less - C: no effect

A: C


Problem: Process: - The body&#x27;s temperature increases over 98.6 degrees F - The hypothalamus in the brain sends a message to the body - Sweat glands in the skin receive the message - The sweat glands start combining water and chemicals to make sweat - The sweat leaves the skin through pores.  Question: suppose heart race begins to increase happens, how will it affect LESS body cooling occurring.  - A: more - B: less - C: no effect

A:
