Answer:
GnRH
Explanation:
GnRH stimulates pituitary secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH and FSH then stimulate the ovaries, resulting in the growth of secondary preantral follicles and ovulation.
Although some release hormones are also secreted in pulses, GnRH is unique because pulsed gonadotroph stimulation is necessary for normal LH and FSH synthesis and secretion, while continuous infusion of GnRH - or the use of such an agonist hormone that stimulates continuous infusion - results in negative modulation of gonadotropic responsiveness to GnRH. This property is clinically used to treat hormone-responsive conditions such as endometriosis and precocious puberty.
Answer:
The need for resources will make the organisms competitive in their ecosystems.
Im pretty sure your answer is b.
They both use a reproductive strategy called alternation of generations, where there are two different reproducing morphologies: a diploid sporophyte, and a haplod gametophyte. The sporophyte produces spores by meiosis (2N -> N), which disperse and form the gametophyte, which produces gametes by mitosis (N ->N). Two of those gametes fuse to create a diplod zygote (N + N -> 2N), which becomes the new sporophyte
There are differences between the two types of plants, especially the relative size of the sporophytes and gametophytes, but they both use this kind of reproductive strategy.
