They ALL have DNA made of the same basic components, but the way that it's organized is different (circular in prokaryotes, linear in eukaryotes, typically). Prokaryotes and eukaryotes have different ribosomes and eukaryotes have membrane bound organelles.
<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.
The first triploblastic phylum is Platehelmenthis
For the answer to the question above, the answer is plasmas.
Plasma<span> is a form of matter in which many of the electrons wander around freely among the nuclei of the atoms. </span>Plasma<span> has been called the fourth state of matter, the other three being solid, liquid, and gas. The electrons in a solid, liquid, or gaseous sample of matter stay with the same atomic nucleus.
