Colonized countries are forced to rely on manufactured goods from their mother countries and prevents development of industry.
Answer:
The circulatory system
Explanation:
The heart, veins and arteries works together to service the cells of the body
Answer:
sigma subunit
Explanation:
Sigma subunit of RNA polymerase holoenzyme directs the enzyme towards the consensus sequences present upstream of the transcription start site. Completion of the initiation phase of transcription is followed by dissociation of sigma subunit from the transcription complex.
The protein NusA replaces the sigma subunit. The RNA polymerase leaves the promoter and starts the elongation
.
Answer:
The inhibitory transmitter activates ligand-gated potassium channels
Explanation:
When a cell is in hyperpolarized state,the potassium gated channels are taken longer time to close up, Therefore, more K+ leaks out of the axoplasm to the exterior.Therefore the cell appears to continue in the resting state, with more negative value of the cell potential of (-120 mV) and this called hyperpolarization.
However, with the addition of inhibitory transmitter,the ligand-gated potassium channels are activated,Theses channels closes up.Then sodium gated channels, which were initially in refractive state reopens, sodium ions diffuses inwards for depolarization, and the neuron returns to depolarized state.
Sound waves enter the outer ear and pass into the ear canal where the waves cause the eardrum to vibrate.
Hope this helps you.<3
