FSH and LH are the main sex hormones in humans called gonadotrophins. They are secreted by the anterior pituitary gland. They act on the gonads; testes in males and ovaries in females. LH stimulated the production of testosterone by the testes while the hormone stimulates ovulation in females. FHS promotes sperm production in males while it stimulates maturation of ova in female ovaries.
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.
Carrying Capacity. For a given region, carrying capacity is the maximum number of individuals of a given species that an area's resources can sustain indefinitely without significantly depleting or degrading those resources. Reproductive lag time may cause the population to overshoot the carrying capacity temporarily.
