nebular hypothesis
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
Answer:land pollution (i think)
Explanation:
Melanomas are rare to occur but must be removed quickly to prevent them from spreading.
Melanoma is also called "the most serious skin cancer disease" because it can spread very quickly. Melanoma can develop within a mole that is already present on our skin and appear suddenly as a dark spot on the skin that looks different from the remaining types of mole.
Early diagnosis and treatment of Melanoma type of cancer are of great importance so we can conclude that early treatment of Melanomas can prevent it from spreading.

For Hypothalamo-Pituitary-Adrenal Axis of endocrine gland secretion, follow the root "CORTI" (C). This will be a great memory tool. Also, nearly all hypothalamic hormones that stimulate anterior pituitary secretion have the word RELEASING (hence "R" in their acronyms). So if asked what secretes CRH, GnRH, TRH, or GHRH... the answer will be the Hypothalamus because of the R.
Now... back to CRH... we're following the "C" for CORTI. What other endocrine hormone has C for CORTI??
ACTH = Adreno[Corti]coTropic Hormone
Which will then stimulate secretion of [Corti]sol (a glucocorticoid), amongst others from the cortex of the adrenal gland. Notice the [Corti] follows the whole pathway from Hypothalamus to adrenal Cortex: Hypothal. (CRH) --> Ant. Pituit. (ACTH) --> Adrenal Cortex (Cortisol)
Sorry this was so long-winded, but I was hoping to help you grasp a portion of how the Endocrine System works!
Good luck and hmu should you have any further Anatomy/Physiology questions.
