Which of the following is an example of homeostasis? Choose all answers that are correct as there may be more than one correct answer.
Show answer choices
The body shivering when outside in the cold.
The release of insulin after a meal to encourage your body to absorb the sugar from your blood, thus lowering your blood sugar.
Producing sweat when outside on a hot day that can evaporate into the air.
Breathing faster while exercising to add more oxygen to the blood and remove excess carbon dioxide from the blood.
Stretch receptors in your blood vessels detect when blood pressure is high and send signals to increase the diameter of your blood vessels and reduce the output from the heart to lower your blood pressure.
Which is/are example(s) of negative feedback?
Select ALL that apply
A. when your body gets too hot, the body starts to sweat, which helps cool you down
B. when a pathogen is detected, an immune cell releases cytokines, which signal other cells to release cytokines, increasing the total number released over time
C. when too much glucose builds up in the blood, insulin is released so that cells will absorb the glucose
D. when you have a cut, platelets activate and work to form a clot, which signals more and more platelets to activate and help form the clot
Which of the following best describes an example of negative feedback?
The body starts shivering to generate heat when you detect you are too warm.
The feeling of hunger after you've just had a big meal.
The increase in breathing rate when the body detects you are low on oxygen and high on CO2.
A decreased heart rate in response aerobic exercise.
The body sweating when the temperature gets too cold.

- Positive feedback loops are the opposite of negative feedback loops. In a positive feedback loop, any change in the original variable triggers mechanisms that actually push the variable further in the direction of the change. Imagine that body temperature was regulated in this way. Briefly explain what would happen.arrow_forwardA scientist wants to study how the body uses foods and fluids during a marathon run. This scientist is most likelyarrow_forwardcreate your own diagram by illustrating how the positive and negative feedback mechanism works. You should use specific condition in the body like (temperature regulation, osmotic balance and glucose levels). Make your diagram creative and presentable by making use of colors and other art materials and don’t forget to put labels on your work.arrow_forward
- If the oxygen level in the blood decreases, the brain sends a message to the lungs/diaphragm to breathe faster, which increases the levels of oxygen in the blood. This describes a negative or positive feedback loop.arrow_forwardIn the 2015 census, Albertans spent 30% of their budget on food purchased from restaurants. A lot of the food purchased is in the form of fast food. Fast food is often high in fat and sodium and low in nutrients and minerals such as calcium. Hypocalcemia, or low levels of calcium, may result in brittle nails, broken bones, muscle cramps, mental confusion, and seizures. Select the actions below that would help the body to maintain homeostasis if blood calcium levels are low. 1. Low levels of blood calcium are detected by thyroid gland. 2. Low levels of blood calcium are detected by parathyroid gland. 3. Parathyroid hormone is released. 4. Calcitonin is released. 5. Bone is broken down to release calcium. 6. Muscle is broken down to release calcium. 7. Calcium uptake by the kidneys and intestines increases. 8. Calcium uptake by the kidneys and intestines decreases.
