<h3><u>Answer;</u></h3>
d. a neuron recharges before it can fire again.
<h3><u>Explanation;</u></h3>
- <em><u>Refractory periods are a short phase in time following an action potential where another action potential cannot be generated. </u></em>
- <em><u>It is the period immediately following the transmission of an impulse in nerve or muscle, in which a neuron or muscle cell regains its ability to transmit another impulse. </u></em>
- There are two types of refractory period, that is the absolute refractory period and the relative refractory period. Absolute refractory period is the first part of a refractory period during which, the neuron will not fire again no matter how great the stimulation and this only lasts for a short time.
- Relative refractory period occurs when a stronger than usual stimulus is required to trigger the action potential before the neuron returns to resting state.
1 one is correct.....he never think about linkage......later after chromosome mapping it was found that Mendel was lucky that they don't show much linkage !
The balanced equation for photosynthesis is <span>6CO2 + 6H2O + light energy = C6H12O6 + 6O2 which is the formula. ;) Hoped I helped!</span>
•observation
•smell
•touch
•they also look at the plant and see the features or the characteristics
Hope this helped you tell me if it does and say thanks plz xoxo
