3 0

Answer:

Explanation:

The key difference between protostomes and deuterostomes is the fate of the blastopore during their embryonic development. The blastopore in a protostome develops into a mouth, where as the blastopore in deuterostomes develops into an (a n a l) opening.

Protostome- Blastopore develops into a mouth. Spiral, determinate cleavage. Schizocoelous formation of the coelom. Annelids, mollusks, and arthropods

Deuterostome- Blastopore develops into an anus. Indeterminate cleavage. Radial cleavage pattern during early development. Echinoderms and the chordates.

Both- Distinct evolutionary lines of coelomates. Complex skeletons that allow them to be highly mobile. Bilateral symmetry. Triploblastic.

The surge in luteinizing hormone that occurs during the middle of the ovarian cycle triggers
avanturin [10]
<h2>Ovulation   </h2>

Explanation:

In women, luteinizing hormone carries out different roles in the two halves of the menstrual cycle

  • In week one to two of the cycle, luteinizing hormone is required to stimulate the ovarian follicles in the ovary to produce the female sex hormone, oestradiol
  • Around day 14 of the cycle, a surge in  luteinizing hormone levels causes the ovarian follicle to tear and release a mature oocyte (egg) from the ovary, a process called ovulation
  • For the remainder of the cycle (weeks three to four), the remnants of the ovarian follicle forms a corpus luteum
  • Luteinizing hormone stimulates the corpus luteum to produce progesterone, which is required to support the early stages of pregnancy, if fertilization occurs
