<span>Hazards from huge explosive eruptions comprise extensive ash-falls with small glass particles in it, pyroclastic flows (combinations of hot gases and pumice chunks), and immense lahars which are volcanic mud flows which can even include debris. These put people within the area in danger. Nearby properties get damaged as well within a circumference of tens to hundreds of miles away from the volcano. These eruptions can extensively cause a change to the global climate too. Hazards from quiet eruptions include lava flows which contain exploding fires and creating gas clouds which are rich in chlorine where lava pours into the sea. This can cause damage to wildlife and sea creatures.</span>
Answer:
3rd option - humans chose the potential parents for crosses based on desired characteristics.
Explanation:
Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Answer:
B. The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell.
Explanation:
Given;
electronic configuration of 6d⁵
where;
6 in the configuration shows that, the principal quantum number (n) is 6
d is the subshell
d orbital has angular momentum quantum number (l) of 2
s orbital, l = 0
p orbital, l = 1
d orbital, l = 2
f orbital, l = 3
5 in the configuration means that there are 5 electrons in the subshell
Therefore, 6d⁵ symbol means that "The principal quantum number (n) is 6, the angular momentum quantum number (ell) is 2, and there are 5 electrons in the subshell".
