Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species <em>could </em>lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
I hope this helps. Have a great week!

Answer:
Calcitonin- reduce blood calcium level
Parathyroid hormone- Raise blood calcium level
Explanation:
The thyroid gland is an endocrine gland which secrete its hormone in the blood directly. Both calcitonin and parathyroid hormone are released by the thyroid gland. Parathyroid hormone is released when the blood calcium level is low.
Parathyroid hormone increases the blood calcium level by osteoclast stimulation which releases calcium from bones and increases blood calcium level. Calcitonin is antagonistic to parathyroid hormone and it reduce the blood calcium level in the blood by stimulating the activity of osteoblast.
