False, secondary succession can also occur from natural disasters, when the environment is destroyed but a bit remains and is able to prosper again
<h3>
Answer:</h3>
C). Cities give people places to live with smaller land use
<h3>
Explanation:</h3>
The reason why answer choice "C). Cities give people places to live with smaller land use" is the correct answer is because cities allow a higher population without using so much land.
Cities are more populated than rural areas, that's because cities can hold more people in it than in rural places.
In cities, you would typically see more buildings that are getting taller, which allows the building to accommodate more people in it. Buildings that are getting higher could have more people in it than homes that take up more land for a small home.
Rural areas would typically have more homes that take up more land, due to the fact that the homeowners would own most of the land around it. The homes in rural areas are mostly occupied by a family, not allowing more people to live in it.
This is the reason why the population density is higher in cities than in rural areas.

For this case what you should know is the statement of the first law of thermodynamics.
By definition, we have to:
- <em>This law establishes that energy is not created, nor destroyed, but is conserved.
</em>
- <em>Then we have that when a certain system is subjected to a thermodynamic cycle, the heat given by the system will be equal to the work received by it, and vice versa.
</em>
In equation mode we have to:
Where,
- <em>Q: heat
</em>
- <em>W: work done
</em>
Answer:
A) Energy can not be created or destroyed.
Answer:
For the sympathetic nervous system:
i. the preganglionic neurotransmitter is acetylcholine, while
ii. the postganglionic neurotransmitter is norepinephrine
For the parasympathetic nervous system both pre- and postganglionic neurones use acetylcholine as their neurotransmitter.
Explanation:
Sympathetic and parasympathetic nervous system are the two components of the autonomic nervous system.
The sympathetic system arises from the the thoracolumbar (T1-L2) region of the spinal cord.
The parasympathetic nervous system originate from
i. the cranial nuclei in the brainstem (brainstem nuclei cranial nerve III, VII, IX, and X), and
ii. sacral nerves (S2-S4).
Preganglionic and postganglionic neurones link both sympathetic and parasympathetic systems to their effector organs.
At synaptic junctions in the autonomic ganglia ththe preganglionic neuron of both sympathetic and parasympathetic nervous system use cholinergic neurotransmitter (acetylcholine). The postganglionic neurotransmitters are not the same for both sympathetic and parasympathetic systems. The sympathetic uses norepinephrine (adrenergic) while the parasympathetic maintains the acetylcholine.
