The correct answer of the given question above would be Meiosis-Prophase I. When you are looking at a cell through a microscope and see that a tetrad has formed, the phase of meiosis that the cell is in is in the Prophase I. This is when homologous chromosomes pair with one another to form tetrads. Crossing over occurs. Hope this answer helps.
The answer to this question is <span>membrane potential
The gradient of electrolyte concentration from inside cell and outside cell will determine the membrane potential. Natrium or sodium is much higher outside the cell than inside cell. In contrast to the sodium, potassium is much more inside cells. This two electrolyte have major role in the membrane potential and action potential. </span>
<span>Each genus contains one or more species. There are 8 main taxonomic groups in biological classification. These are, from the most inclusive to the least inclusive: domain, kingdom, phylum, class, order, family, genus and species. Therefore, each genus contains one or more species.</span>
