identify the subcellular structure of the neuron that forms the basis for the transmission of nerve impulses. (2 points) describ
melisa1 [442]

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:

  1. The neurotransmitter molecules are stored in synaptic vesicles.
  2. If the neurotransmitter leak from the vesicles, they are destroyed by enzymes.
  3. During resting condition, they are placed randomly.
  4. 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.

How would the biodiversity and biomass of an ecosystem, change over time as ecological succession occurs? Give an example as par
DedPeter [7]
The biodiversity would change over time through ecological succession.  This can be done many ways.  One way would be through a damaging event, such as a forest fire or flood.  Then, a pioneer species would start growing.  A pioneer species would then lead to increased biodiversity in both antibiotic and biotic factors, therefore strengthening the ecosystem even more. 

I hope this helps!! Can I have Brainliest, please? :)

After allowing his F1 crosses to self-pollinate, Mendel observed that
frutty [35]

Answer:

Explanation:

First-generation (F1) progeny only showed the dominant traits, but recessive traits reappeared in the self-pollinated second-generation (F2) plants in a 3:1 ratio of dominant to recessive traits. Mendel then crossed these pure-breeding lines of plants and recorded the traits of the hybrid progeny
