Why are "Homeostasis" and "Feedback" in the same category? (AKA how are these vocabulary words similar but different)
Homeostasis is defined as the body's ability to maintain a "normal" range of internal conditions. (Ex. outside temp changes, body temp stays around 98*)
Feedback, or feedback mechanisms, means "what your body does and how it does it, to be able to stay normal". (Ex. when we get too hot our skin sweats to cool us off)

Correctly name all 2 INPUTS and all 3 OUTPUTS of Cellular Respiration.
IN______ + ______
-> ______+_______+______ OUT
O2 oxygen + C6H12O6 glucose -> ATP energy + H2O water vapor + CO2 carbon dioxide

If "regulation" means "to control", then what does "Thermo" and "Osmo" mean?
____________, ______________
Temperature, Water

"Evolution involves change over time."
Rewrite this sentence to be more specific. Include the vocab words "populations," "environment," "survive," "reproduce," and "fit."
Populations evolve over time to be more fit. When the envi. changes, the most fit organisms have the best chances of survival and reproduction.

Feedback Mechanisms are the mechanisms(things that do things) that help us maintain homeostasis because they let us ___________ and ____________ to environmental stimuli. This feedback helps us adjust our body to combat changes that disrupt homeostasis.
Sense/recognise/notice/become aware of, Respond/react/take action

Describe how 3 body systems work together during cellular respiration.
Reminder: body systems include Digestive System, Circulatory System, Integumentary System, Reproductive System, Excretory System, Immune System, Musculoskeletal System, Respiratory System, Endocrine System, Cardiovascular System.
Systems involved: Respiratory (O2/CO2 gas exchange), Circulatory (transport in/outputs), Digestive (absorb glucose inputs).
*the Excretory System is responsible for getting rid of H2O but in a different way (pee/poo) = incorrect response

Thermoregulation helps your body to maintain a "normal" or set range of internal conditions. Draw a simple line graph (X/Y axis, set point, 1 data line, that's it) to show Thermoregulation taking place in your body throughout one day (24 hours).
Hint: draw the "Set Point" as a dashed or dotted line across your graph and label it "set point", then add a solid line to show hypothetical body temp. data. Homeostatic temperature range of humans = ~98.6* +/- 2ish degrees
X and Y axis are drawn (no labels ok), single solid line fluctuates a tiny bit up/down about the labeled set point (98.6*).
*extreme fluctuations, ie. going from 0* to 200* is not acceptable. You would die. I will accept logical temp changes only.

In Unit 2: Humans Vs Bacteria we learned about the evolution of populations of bacteria. Why did one of our labs have Rock Pocket Mice as the "main characters?"
Hint: explain what you learned from this model organism's population to help you better understand bacterial populations.
Mice are a familiar species to us, whose populations we can easily see and study. We learned that when the environment changes, populations must adapt. Certain traits allow for better chances of survival than others and get passed on to offspring during reproduction. This applies to all organisms. Bacteria are organisms.

The things in the body (usually found in the hypothalamus) that are responsible for getting all sorts of signals or messages from environmental stimuli are called ____________?
Receptors !!! are receptive to the signals they recieve

What happens to the Oxygen concentration (level/amount of O2) in Zoeyi's blood as it circulates throughout her body when she runs down the hall to Miss S's class? What does her body do to maintain homeostasis when this change in normal/resting O2 concentration happens?
As she runs she needs to make/use energy. To make energy we need to take and use the Oxygen out of the blood. If the O2 is being taken by the Mitochondria and turned into something else, then it isn't in the blood anymore. The concentration starts to go down. She needs to breathe faster while running to keep it up at "normal" levels.

During the Osmoregulation Lab we looked at plant cells under the microscopes. We saw what happened when the cell goes from normal (part of the plant) to submerged in(cut off and sunk under) a super salty salt water solution. The solution had wayyyyy more parts dissolved salt than parts water in it Assume the cell is filled up with 0% salt and 100% water in it to start. Use at least 1 verb and 1 adjective (1 action word/1 describing word) to explain what happened under the microscope after a few minutes.
Hint: high to low
Verb: moves/flows/balances/changes/disperses/exits, dilutes, leaves, etc.
Adj: deflated, shrunken, shriveled, small, smaller, empty, etc.

Humans aren't the only organisms capable of sensing and responding to the environment. This is something all living things do and is actually a requirement for something to being classified as "living."
As a group or "one-man-act", act out 1 way plants react to changes their environment. Someone MUST narrate. Actors ARE silent!!! no props obtained from farther away than reaching distance, sorry, sit down.
Hint a: Gas Exchange
Hint b: Circadian Rhythms
It has to make sense

Cellular Respiration involves inputs and outputs. Photosynthesis also involves inputs and outputs. How are these chemicals/molecules that are going in and out during Cellular Respiration and Photosynthesis similar? how are they different? Be SPECIFIC!!!
Similar: they both involve the same exact set of chemicals/types of molecules. H20,CO2,energy (ATP or sunlight),Glucose, and O2 are the 5 things involved in both processes.
Different: they are opposites. in for one =out for the other, out for one =in for the other. We rely on each other to make/get rid of different of the same things. Also, ATP and sunlight are 2 different types of energy and get labeled slightly different on a model or in chemical equation

When your brain senses that you are becoming dehydrated, hormones tell your __________s (lima bean shaped organs that you have 2 of) to reabsorb ________ back into the bloodstream instead of peeing it out. This means your pee looks more ___________(color). This helps us maintain osmotic(water) balance.
kidneys, water, dark/yellow

Explain: populations of organisms survive, reproduce, and over long periods of time/many generation, eVoLuTion CAN occur, BUT this can't happen unless...
Hint: The "multiple choice" style lists in your review packet is more like a checklist for perfect conditions. Meaning, any combination of those options allow for evolution to happen. Can you remember any?
Like all populations of organisms, bacteria can only evolve over time if…
(1) there is potential for the population to increase in number
(2) there is heritable (able to be passed on in DNA) genetic variation (variety of traits) between individuals (due to sexual reproduction and/or random mutations)
(3) There is competition for limited resources (ex. not enough food where the population lives)
(4) the proliferation(rapid increase) of those organisms that are better able to survive and reproduce in the environment.

What do 12AM and 12PM look like on an analog clock? (the little and big hands point where)
Hint: a broken clock is still right 2 times a day
both hands point to 12. AM/PM is not told to you. AM starts when you should be asleep. PM starts at lunch time/noon. Look out a window.

Imagine all of the terrible things that could happen to you if you are "non-receptive" to environmental stimuli. In the next 60 seconds create a short 3-4 sentence SCHOOL APPROPRIATE story about your favorite teacher (Miss S obvi) going to school on a day where this happens :0
Tell the story without saying "uuuhhmmm" or "like" or pausing for a long time to think
These better be good, friends
If I hear Ummmmm Like Like like .......uhhhh ..... .. NO POINTS!!! NEXT

Draw a model to show what happens to KayDen's rate of cellular respiration when he goes from standing around the football field to running all the way to the other side (120 yards). Include all inputs and outputs with arrows to show in/out happening. Indicate how the rate, or speed, of the in/outputs change by clearly labeling the model.
Model must include: human shaped outline/sketch, in/outputs labeled correctly, some indication of an increased rate of in/outputs is CLEARLY included.
*verbal additions to response not accepted. Done drawing/labeling=done answering. (It needs to make sense without explaining it)

Fully and accurately explain, going one image at a time, all of the pieces of information that this model is trying to communicate with us. Base your response on what you see below and what you know already. 
1. Solution outside is superrrrrrr hyperrrrr-salty/sugary/tonic-y so water moves out to try to balance this and the cell shrinks
2. Solution is looooow hypoooo-salty/sugary/tonic-y which means it must have water taking up room. The cell doesn't have as much water in it. Water flows in and the cell might burst from getting too full.
3. balanced= no net movement

Fill in the blanks: Kanna tried milk and got sick. This is because she didn't inherit the helpful hereditary trait called ___________ ______________. Unlike her friend Alissa, her body does not continue producing the enzyme she needs to breakdown (AKA _ _ _ _ _ _ ) the disaccharide sugar in her milk. Instead her gut bacteria get to "eat" it and make gas in her digestive tract :(
Kanna's hereditary material (fancy word for the _ _ _ she got from her parents) contains sections of unique combinations of the chemicals A,C,T,G. Sections that code for specific traits are called coding _ _ _ _ s. There are also sections called non-coding - - - -s (parts that don't direct the production factory in your cells AKA the ribosomes, instead they do mysterious things like keep - - - - s "switched" _ _ . )

Teach the class about Osmosis. If you mess up as the teacher you skip your turn. The class hasn't been taught unless you can provide sufficient evidence that they learned something. Without enough evidence to support your claims of amazing success, I will tell you you're just lucky (your teaching skills are correlated to but not causing good grades). To do this you will need to quiz everyone on what you taught them between when I say GO and when I say STOP. You have 1 minute to meet with me for help. Everyone else, please behave as you normally would on a Monday after a 2 week break. (:
Pass/Fail no arguing or you are disqualified from these points
