The ovarian cycle describes the monthly events of a post-pubescent ovary that causes a small number of primary follicles to grow
garik1379 [2080]

Answer:

The ovarian cycle manages the preparation of endocrine tissue, and the release of eggs within the female body.  

The ovarian cycle consists of a follicular phase. Gradual increases of FSH and LH stimulatethe growth of follicles on the surface of the ovary. This progression ensures that the egg is ready for ovulation. As the follicles mature, they beginto emit estrogens and maintain low levels of progesterone. Progesterone secures the endometriumto help facilitate pregnancy. The ovum takes about seven days to journey through the Fallopian tube and implant in the uterus. At this stage, the cells number around 30-60 and are identified as the morula. If pregnancy does not occur, the lining will be shed. Estrogen levels rise after roughly five days, leading the menstrual cycle into the proliferative phase. The endometrium initiates regrowth to replace the weakened blood vessels and glands from the previous cycle.

garik1379 [2080]

Response:

Pequeñas cantidades de un mutágeno no suelen afectar la salud

Clarificación:

Los rayos X son una forma de radiación electromagnética utilizada como herramienta de imagen para observar las estructuras internas. La radiación de rayos X se produce cuando una partícula cargada impacta un material a una alta longitud de onda.

La exposición a la radiación de rayos X se ha demostrado que causa serios problemas de salud, ya que se conocen por inducir mutaciones, es decir, son mutagénicos, especialmente si se presentan en grandes cantidades o dosis. Por lo tanto, en el caso de María, quien estuvo expuesta a una pequeña cantidad de radiación por rayos X, es probable que el médico le informe que pequeñas cantidades de un mutágeno (rayos X) generalmente no tienen un impacto en la salud.
