<span>This hyperpolarization is due to the exiting of potassium ions or the influx of chloride ions through the channels in the neuron. During this time, the neuron enters a refractory period (approximately 2ms), during which an action potential is unable to be transmitted. After this timeframe, the neuron resets to around -70mV and the cell becomes able to re-transmit an action potential.</span>
Answer:
True
Explanation:
Blood pressure refers to the pressure applied by the blood on the arteries when the flow through it. In reality, the pressure of the blood is the pressure applied by on the blood during the pumping of the blood.
When the ventricles of the heart contracts, the pressure of the heart are very high which can be measured around 120 mm of Hg and is known as systole pressure.
When the pressure on the blood level applied during the ventricular relaxation during which the ventricles get filled with the blood is represented as 80 mm of Hg. This relaxation phase pressure is represented as diastole blood pressure.
Thus, true is the correct answer.
It is d
Explanation: 40/30=0.75 because there are 40 flowers in total and only 30 are red so the % of there being red flowers is 75% or 0.75 (same thing)

Respiration is done aerobically, using oxygen. a similar process is fermentation, yet it is done anaerobically, without oxygen. Fermentation, as a bi product, produces ethyl alcohol.
