Homeostasis
What are the four stages of the stimulus response model?
Stimulus
Receptor
Control/coordination centre
Effector
The body has 3 lines of defence. Give three examples for the first line of defence.
Skin
Mucous
Hair
Tears
What is the outermost layer of the Earth?
Crust
What is most likely to occur at oceanic-oceanic diverging plate boundaries?
Sea floor spreading
What is the role of photosynthesis in the carbon cycle?
To take in carbon dioxide and expel oxygen which assists all living things with survival
Which part of the brain is responsible for the regulation of homeostasis?
Hypothalamus
Give two examples for the second line of defence
1. Phagocytosis
2. Fever
3. Inflammation
List four greenhouse gases
What two things are common at transforming plate boundaries?
Earthquakes
Fault lines
What spheres does the carbon cycle interact with?
Which receptor is responsible for detecting changes in temperature?
Which receptor is responsible for detecting changes in chemicals?
Thermoreceptors
Chemoreceptors
What are two main differences between type 1 and type 2 diabetes?
1. Diagnosis age
2. What causes it - lifestyle vs. genetics/autoimmune
What gas makes up most of the Earth's atmosphere?
Nitrogen
What are fault lines?
Fractures in the Earth where tectonic plates have slipped and an earthquake has occurred
How do humans affect the carbon cycle?
Burning fossil fuels and using too much non-renewable energy releases excess carbon into the atmosphere which disrupts the cycle and affects the Earth
What are effectors?
Muscles and glands
What are pathogens?
An infectious agent which causes illness or disease to its host
Are too many greenhouse gases a bad thing? And why?
Yes, contributes to climate change which affects the Earth, animals on the Earth and the climate
In oceanic-oceanic and oceanic-continental converging plate boundaries, which plate is most likely to subduct?
And Why?
oceanic - oceanic - older oceanic
oceanic - continental - oceanic
They are more dense
Define decomposition
Decaying of organic waste
List the three different types of neurons and where they communicate within the stimulus response model
1. Sensory - receptor -> CNS
2. Relay - CNS -> CNS
3. Motor - CNS -> Effector
When is someone more likely to get a disease?
If they are immunocompromised, stressed, already sick, run down, unhealthy, living in unhygienic conditions
What is the lithosphere made up of? What two part of the Earth?
Crust and upper mantle
What is the most famous example of a transforming plate boundary? Hint: it is in California
San Andreas Fault
True or false:
When plants/animals decay, all of the carbon is released back into the atmosphere
False - some goes into the ground and becomes fossils and fossil fuels
