Explanation:
b. Bromo cyclopentane + HBr
Answer:
2.The cooling effects of more indirect sunlight cause autumn and winter. Because of the Earth's approximately 23.5º tilt, the seasons in the Northern and Southern Hemispheres are reversed, about six months apart from each other.
3.In North America, around June 21, Earth tilts on its axis toward the Sun.

Explanation:
Answer: Holmium-165 = Er-165 + electron
Explanation:
Beta decay is the decay of a neutron into a proton and electron. This will increase the number of protons in the Holmium nucleus by one, making it Er, Erbium, with the same atomic mass.
Holmium-165 = Er-165 + electron
The mass is essentially the same, as the proton is assigned the same mass as the neutron it came from.
Answer:
A hot spot is an area on Earth over a mantle plume or an area under the rocky outer layer of Earth, called the crust, where magma is hotter than surrounding magma. The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.
Hope this is what you mean be hot spot!
I hope this helps you!
Have a great day
