- How do the organisms get energy from the deep-sea vents?
- How are the organisms able to live under the water pressure?
- Are the organisms mostly producers or consumers?
Answer:
microvilli, actin filaments
Explanation:
The apical ends of intestinal cells face the intestinal channel and have long processes that facilitate the absorption of nutrients. the name of these processes is microvilli and actin filaments from the cytoskeletal element forms their internal skeleton.
Answer:
Mutations Are Recessive or Dominant
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.

<span>Decomposition reaction is where an organism undergoes breakdown into simpler molecules and compounds. This is caused by other biotic and abiotic factors in the environment. Simply, decomposition is part of a cycle where a complex compound is breakdown and used again for complex reconstruction of other organic processes. </span>
