In the period when the lush ancient forests exited on Earth, the ones that provided the material for the formation of the coal that we use nowadays, Australia did not provide the right conditions for the existence of these forests.
The problem was that Australia was located very close to the South Pole in that period. Because of its location, Australia was colder and drier than most of the landmass on the Earth. By having less precipitation, and colder climate, Australia was not suitable for the tropical rainforests of that period, thus it did not had the material from which the coal formed latter on in the geological time scale.
I'd say precipitation, it won't be alive though so biodiversity is wrong
Answer:
Hormone levels are changing during menstruation and ovulation. The general trend of hormones after ovulation -when an individual approaches menstruation- is that hormone levels generally decrease.
Explanation:
In a woman's menstrual cycle, hormone levels tend to increase or decrease according to reproductive requirements. On the days close to ovulation, the hormones must prepare for the release of an egg and the preparation of the female reproductive organs for the possibility of an embryo.
If fertilization of the egg does not occur, hormone levels generally tend to decrease until menstruation occurs.
In the attached graph (picture) the behaviour of hormones in an adult woman can be clearly seen, where estradiol, follicle-stimulating hormone, progesterone and luteinizing<u> hormone tend to decrease their levels at the end of the luteal phase, in the proximity of menstruation</u>.
