Answer:
Photosynthesis is the process by which plants make their own food.
Answer: Horizon O forms from organic material. And Horizon C is least affected by the soil formation process. Bedrock lies below the soil layers.
Your pupil expands in dim light and contracts in bright light.
it goes sedimentary rock to metamorphic is heat and pressure
then metamorphic to magma is melting and magma to igneous rock is crystallization

The subcellular structures of neuron that forms the basis for transmission of nerve impulses are the synaptic vesicles.
What are the steps in impulse transmission between neurons?
- The action potential or nerve impulse reaches the <u>axon</u> of neuron and depolarises the membrane.
- Voltage gated Calcium channels open .
- Arrival of action potential causes the synaptic vesicle to attach to presynaptic membrane.
- Calcium influx triggers release of neurotransmitter.
- This neurotransmitters bind to postsynaptic membrane and new impulses are created.
Synaptic vesicle under resting condition:
- The neurotransmitter molecules are stored in synaptic vesicles.
- If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
- During resting condition, they are placed randomly.
- When an impulse reaches the axon, vesicles are arranged in the presynaptic membrane.
Thus from the above we can conclude that, synaptic vesicles are the subcellular structures in transmission of nerve impulses and , under resting condition they are placed randomly.
