In the ovarian cycle, the surge of LH triggers ovulation.
During evolution when the level of estrogen is sufficiently high, it produces a sudden release of LH, usually around day thirteen of the cycle. This LH peak triggers a complex set of events within the follicles that result in the final maturation of the egg and follicular collapse with egg extrusion.
A surge in LH causes your ovary to release a mature egg around the second week of each menstrual cycle. A high LH level around this time means that you're at that moment in your cycle when you're most likely to get pregnant. Levels of LH are low for most of the monthly menstrual cycle. However, around the middle of the cycle, when the developing egg reaches a certain size, LH levels surge to become very high.

Answer:
D. Sistema reproductor.
Explanation:
La excreción es el proceso de eliminar los desechos y el exceso de agua del cuerpo. Estos desechos pueden ser dañinos y pueden causar daños.
Los órganos responsables de la excreción son el riñón, los pulmones, la piel, el hígado y el intestino grueso.
La piel elimina el sudor, el exceso de agua y las sales a través de las glándulas sudoríparas.
El sistema urinario está formado por riñón, uréteres, vejiga y uretra. El riñón elimina el exceso de agua y sal al producir orina que luego se transporta con la ayuda de los uréteres, la vejiga y la uretra.
En el sistema respiratorio, los pulmones excretan sustancias gaseosas, como dióxido de carbono y agua.
After the G2 phase, the cell goes thru another growth period. The cell will gather energy in order to prep for whats coming: Mitosis. The first phase of mitosis is Prophase. During Prophase, the chromatin fibers condense and shorten to chromosomes that can now be seen with aid from a light microscope. Microtubules also appear and prepare to hold sister chromatic im correct alignment for separation. Metaphase is the second phase. Microtubules align sister chromatids at the exact center of the mitotic spindle aka metaphase plate. The following step is Anaphase. The centromeres split, separating the 2 identical sister chromatids. Once the chromatids are separated, they are called chromosomes. Telophase comes after anaphase. It is the final stage of mitosis. The identical sets of chromosomes are now at opposite sides of the cell. The nuclear envelope now re-forms around each mass of chromosomes, nuclei reappear within each nucleus. After these phases, Cytokenisis occurs. This is the division of the cell's cytoplasm and organelles into 2 cells. A cleavage furrow is formed during Anaphase.
