Problem: Process: - Put water in an ice cube tray - Put the ice cube tray in the freezer - Wait 5 to 6 hours - Take the ice cube tray out of the freezer - Bend the tray slightly to get the ice cubes out and into a drink. Perturbation hypothesis: suppose there is no freezer to put the ice tray in happens, how will it affect tray will be put into a freezer. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Bread is exposed to the elements - Bread absorbs water from the air - Bread absorbs warmth from the air - Dust particles with mold spores fall on bread - Mold spores start to consume the bread for energy - Mold colonies grow until they are visible. Perturbation hypothesis: suppose bread has to be kept in the fridge happens, how will it affect bread is kept somewhere more moist than usual. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Contact is made with a virus - The virus enters the human or animal body - The virus goes to the part of the body that contains its food - The virus consumes part of the body or materials that the body uses - The virus replicates and spreads - The virus causes symptoms in the body as the immune system tries to expel the virus. Perturbation hypothesis: suppose a person will be ill more often happens, how will it affect LESS cells being damaged. Does the supposed perturbation have an effect (direct or indirect) on the process?

A: yes

Problem: Process: - Carbon dioxide from the air passes through small pores (holes) in the leaves - These pores are called stomata - Water is absorbed by the roots and passes through vessels in the stem on its way to the leaves - Chlorophyll absorbs the sun's energy - It is this energy that is used to split water molecules into hydrogen and oxygen - Oxygen is released from the leaves into the atmosphere - Hydrogen and carbon dioxide are used to form glucose or food for plants. Perturbation hypothesis: suppose less deep roots happens, how will it affect LESS sugar and oxygen being produced. Does the supposed perturbation have an effect (direct or indirect) on the process?

A:
yes
