Answer:
Option-D
Explanation:
A reflex arc is the neuron pathway which is involved in producing the response to reflex action or the immediate response.
The reflex arc pathway involves the sensory neurons, interneurons and the motor neurons.
Although the reflex arc pathway involves the brain later but in producing response the brain is not involved.
The stimuli are perceived by the spinal cord but not the brain therefore the selected option is correct.
Thus, option-D is correct.
An advantage of using models to represent the carbon cycle is: B. show a complete and detailed account of every event in the cycle.
A carbon cycle refers to the series of biogeochemical processes through which carbon atoms or carbon compounds are interconverted and used by living organisms within an environment, especially by transporting carbon from the atmosphere to planet Earth and then back to the atmosphere.
Basically, there are four (4) main processes that are associated with carbon cycle and these include:
- Combustion such as burning of fossil fuels.
A model can be used to graphically illustrate or simulate the all of the activities (events) that are taking place within the carbon cycle.
Hence, an advantage of using models to represent the carbon cycle is that it would illustrate (show) a complete and detailed account of every event in the cycle.
