100
What comes first: the stimulus or the response?
The stimulus
100
What is the name of the messengers used in the endocrine system?
Hormones
100
Is the nervous system chemical or electric?
Electric
100
What is the difference between a food chain and food web?
Food chain is one path of energy, whereas a food web is many.
100
What is photosynthesis?
How plants get their food/ How plants create sugar and oxygen
200
In the following scenario, identify the STIMULUS. It was a cold day. The dog shivered.
The cold day.
200
How do hormones travel through the body?
Through the blood
200
Is the nervous response short or long lasting?
Short
200
Where would you place the producer level on a food web?
At the bottom
200
What are the three things a plant needs for photosynthesis?
- water - carbon dioxide - sunlight/light energy
300
In the followin scenario, identify the RESPONSE. Amy was at soccer training. A kick gone wrong almost hit her in the head but she ducked just in time.
She ducked.
300
What is the name of the endocrine gland in the neck?
The thyroid
300
What is the part of the brain responsible for muscle memory and physical skill?
Cerebellum
300
Whar the four levels of ecosystems? (HINT: producers are at the bottom)
1. Producers 2. Primary consumers 3. Secondary consumers 4. Tertiary consumers
300
What is one way you could improve the photosynthetic rate of a plant?
Give it more carbon dioxide/water/sunlight. BUT not too much.
400
What is homeostasis?
Where the body is stable at all levels.
400
Is a hormonal reaction voluntary, involuntary or both?
Involuntary
400
Is the nervous system voluntary, involuntary or both?
Both
400
Are primary consumers herbivores, carnivores or ominovres?
Herbivores (they consume producers)
400
What would be the effect of keeping a plant in a vacuum?
No carbon dioxide to access so it would stop photosynthesisig and eventually die.
500
If you were sitting out in the sun (STIMULUS = HEAT), what would your body's RESPONSE to cool down?
Sweating/thirst
500
What are four ways the body could respond using the sympathetic response?
- dilation of airways - release of adrenalin - increased heart rate - increased blood pressure - inhibition of digestion - dilation of pupils
500
What are the five steps in the reflex response?
1. Receptor 2. Sensation 3. Brain/Spinal cord integration 4. Effector 5. Response
500
Draw a food chain and label levels:
Drawing should show: - a food chain - arrows showing energy flow - correctly labelled producers, primary consumers, secondary consumers and tertiary consumers
500
Why might an ashtmatic struggle to live somewhere with no trees?
Very little oxygen.
