Q: Process: - Air enters the nose or mouth and travels through the windpipe into the lungs - The lungs have a series of smaller and finer tubes and sacs - Air reaches the smallest and finest air sacs called alveoli - Oxygen travels from the alveoli into the blood - Oxygen-rich blood is carried to the heart - Oxygen-rich blood is pumped throughout the body by the heart - Cells take in the oxygen rich blood and release carbon dioxide rich blood - The carbon dioxide rich blood travels to the lungs - Carbon dioxide travels through the throat and is exhaled. Perturbation hypothesis: suppose coal is broken down happens, how will it affect a SMALLER amount of oxygen being delivered to the blood stream. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process: - Grass and small plants grow in an area - These plants die - The soil gains organic material - The soil becomes more fertile - Larger plants are able to be supported - Trees eventually grow. Perturbation hypothesis: suppose soil gets the proper nutrients happens, how will it affect if less soil becomes fertile. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: yes

Q: Process: - You start with a glacier - Through warming or other methods a chunk is taken off the glacier - The chunk drifts into the sea - And it settles where it can remain in its state - It is considered an iceberg. Perturbation hypothesis: suppose a tracheotomy is performed happens, how will it affect water temperature increases. Does the supposed perturbation have an effect (direct or indirect) on the process?
A: no

Q: Process: - The air is cold - Water is in the air - The water forms tiny ice crystals - The ice crystals collide with each other - The ice crystals stick to each other - The ice crystals get bigger as more of them stick together - The ice crystals get too heavy to be in the air - The ice crystals become snowflakes - The snow flakes fall to the ground as snow. Perturbation hypothesis: suppose the air is colder happens, how will it affect Less ice crystals will form from the water. Does the supposed perturbation have an effect (direct or indirect) on the process?
A:
yes
