Answer:
The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption. Volcanoes have also caused global warming over millions of years during times in Earth’s history when extreme amounts of volcanism occurred, releasing greenhouse gases into the atmosphere.

THE ANSWER IS A I DIDNT SEE THE TOP
Answer:
No.
Explanation:
No, Surtsey island and Iceland newest volcanic island will not become an atoll because these islands have no underground volcanoes. The atolls are only occur when the volcanoes are present underwater and we know that these volcanoes are present on the lands not in the water so there is no possibility of having atolls in these Surtsey and Iceland volcanic islands
hormones can stimulate cell regulators to increase cell reproduction. Thus option C is correct.
<h3>what are the role of hormones in reproduction ?</h3>
Hormones are the chemical messengers produced by the endocrine cells and it move through the blood, act on target cells.
The two most important reproductive hormones are estrogen in female and testosterone in male.
Estrogen induce the eggs development and maturation process in adult female and released during regular intervals of menstrual cycle.
Testosterone in male responsible for male gamete production.
Other hormones involved, such as Follicle stimulating hormone (FSH), Luteinising hormone (LH).
Thus option C is correct.

Number of moles Aluminium sulfide
1 mole of sulfide contains 150 g
Therefore; 16.2/150
= 0.108 moles
The mole ratio of Al2S3 : Al(OH)3 is 1:2
Therefore; moles of Aluminium hydroxide will be;
= (0.108 × 2)
= 0.216 moles
But, 1 mole of Al(OH)3 contains 77 g
Therefore, the mass of aluminium hydroxide is
0.216 moles × 77
= 16.632 g
