<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.
Answer:
Hydrogen
Explanation:
Elements that have low ionization energies tend to have low electronegativities. The nuclei of these atoms don't exert a strong pull on electrons. Similarly, elements that have high ionization energies tend to have high electronegativity values. The atomic nucleus exerts a strong pull on electrons.
Volcanos cant form there. now i need 20 characters
Saturn is the least dense planet in our Solar System. It is made up of mostly hydrogen and helium, which are the two lightest elements in the universe and thus make Saturn the lightest planet that we know of. This could Possibly be the answer!!
In process
of meiosis. The hypothalamus or the master gland in most animals, including
humans send signals to the ovaries and testes of the reproductive system. In
response to these signals, these ovaries and testes undergoes the sex cells
division which is called meiosis. Spermatogenesis in male gametes, is the
process of sex cell division among sperm cells. On the other hand, oogenesis is
for the female gametes. These cell divisions among respective gametes produces
haploid cell which only contain one pair of chromosomes, in number -23.
In response to this inquiry's question. Simply reproduction.
