Nikki's Story
Nikki visited this country in her story
What is Haiti?
All living things are made of this basic unit of all life
What is a cell (cells)?
A bunch of cells come together to form this
What is a tissue?
Feedback loops help maintain this process in which the body maintains a stable internal environment
What is homeostasis?
Cholera is caused by vibrio, which is a type of this microorganism
What is a bacteria?
What is a solution?
Doing this action was the reason Nikki got sick on her trip
What is she ate and drank dirty food and water? (Accept equivalent phrases)
All living things get this from the sun and/or from eating other living things
What is energy?
This body system contains the mouth, pharynx, and lungs, and involves the breathing in of oxygen and the breathing out of carbon dioxide
What is the respiratory system?
Feedback loops usually help reduce these changes, either externally or internally, to the body
What are stimuli?
Name the way in which you can get cholera into your system
What is from eating dirty food and water?
A concentration ________________ is made when there is a difference of concentration in a small area
What is a gradient?
Nikki had nausea and this condition in which your stool is watery
What is diarrhea?
All living things maintain a stable internal environment, and it is called this
What is homeostasis?
A bunch of organs come together to form these
What are organ systems/body systems?
This type of feedback loop reduces a stimulus and returns the body to a set point
What is negative feedback?
Cholera primarily affects this body system, responsible for nutrient absorption and elimination of wastes
What is the digestive system?
Diffusion is the movement of molecules from an area of __________ to __________ concentration
What is high to low?
Nikki was diagnosed with this disease
What is cholera?
All living things have this molecule of genetics in their cell nuclei
What is DNA?
This body system involves absorption of nutrients, elimination of solid wastes, and transference of nutrients to the blood
What is the digestive system?
This type of feedback loop enhances/increases a stimulus and keeps increasing it until the body completes the action
What is positive feedback?
Cholera's effects can be reversed using this - ions dissolved in a water solution (like PediaLyte)
What are electrolytes?
Osmosis is the movement of _____________ across a semipermeable membrane
What is water or water molecules?
True or false - Nikki's cholera can be easily reversed by electrolytes
What is true?
All living things experience change over millions of years and it is also called this
What is evolution?
A bunch of organ systems come together to form this
What is an organism?
Name any step in the feedback loop (hint, there are four steps!)
set point/normal range, stimulus, receptor and control center, effector and response? (accept word forms)
What is water?
Both diffusion and osmosis are this kind of process in which energy is not used at all when these processes happen
What is passive?
