This document discusses homeostasis and feedback mechanisms in the human body. It contains 5 multiple choice questions and answers:
1. It identifies the 4 main parts of a homeostatic system as sensors, control centers, communication systems, and targets. Each part has a specific function to maintain homeostasis.
2. Negative feedback loops work to return the body to its set point by counteracting changes, while positive feedback loops accelerate changes away from the set point.
3. Nursing creates a positive feedback loop that causes the mother's body to produce milk. If she bottle feeds instead, this stimulus is eliminated and her milk supply will decrease.
4. On a hot hike, negative feedback loops like sweating and increased blood

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

1. A system to maintain
homeostasis must have at least 4
parts that function together. Name
these and parts and briefly explain
what each one does.
Senors – gather information
Control centers – analyze & compares the information to the
desired values
Communication systems – send messages from the control
center to regulate the change
Targets – receive & respond to the messages
3. +
2. What is the main difference
between the way negative feedback
and positive feedback mechanisms
regulate changes in the body?
Negative feedback loops counteract change to return to a set
point.
Positive feedback loops accelerate change away from a set
point
4. +
3. When a newborn baby nurses,
the mother’s body is stimulated to
produce milk. What would happen
to the mil supply if the mother chose
to bottle feed rather than breast
feed? Why?
Nursing a baby creates a positive feedback loop causing the
mother’s body to lactate. Bottle feeding eliminates the stimulus.
5. +
4. Suppose you go on a long hike in
hot weather. Describe a possible
negative feedback loop that would
keep your body from overheating.
Sensors detect rise in body temperature
Increase in blood flow to skin (vasodilation)
Sweat glands activated to cause sweating
Increase in heart & breathing rates
6. +
5. Reptiles regulate their body
temperature by changing their
environment. A snake, for instance, must
lie in sunlight to warm its body.
Mammals, on the other hand, can
regulate their internal environment to
gain or lose heat. How might this ability
give mammals an advantage over
reptiles?
Mammals can live in a wider range of habitats & tolerate rapid
changes in external conditions
