Answer:
The introduction of Coqui frog took place accidentally from Puerto Rico into Hawaii in the year 1988. The introduction of the frog species has posed a danger to the island ecosystem of Hawaii and is also a source of major noise nuisance. The species of the frog has an enormous urge to eating, which is putting the native species of spiders and insects of the island at a greater risk.
The Coqui frog species can even thrive in distinct ecological zones and heights in the region and are also witnessed at the height of 4000 feet above the level of the sea. These frogs can also compete with the local fauna and the endemic birds, which are solely dependent on insects as the source of their food.
Answer:I'm almost positive the answer is A
Explanation:
Answer:
Negative; Estrogens and progesterone
Contraceptive pills mimic the negative feedback effect of estrogens and progesterone.
Explanation:
- <em><u>Estrogens and progesterone are regulated by negative feedback mechanisms, and therefore, birth control pills make use of this fact.</u></em>
- <em><u>Birth controls pills adds extra amount of estrogen and progesterone which inhibits the release of these hormones by the body.</u></em>
- Consequently the release of an egg from the ovary is inhibited and the lining of the uterus is made to become thin and unsuitable for pregnancy by the absence of progesterone hence decrease the secretion of the luteinizing hormone and the follicle stimulating hormone by negative feedback.This process ends up inhibiting ovulation.
