Answer:
Magma hot spot.
Explanation:
Hot spots stay always the same location because they are in the mantle, not in the crust. So, that's why hotspots stay while plates are moving over them.
<span>Waste products in the cell accumulate and are eventually moved out of the cell and eliminated.
Given that these products are waste, and can be harmful to the organism, they need to be eradicated, and thrown out of the system.

Answer:
The rate of the catalyzed reaction will increase by a 1.8 × 10⁵ factor.
Explanation:
The rate of a reaction (r) is proportional to the rate constant (k). We can find the rate constant using the Arrhenius equation.
where,
A: collision factor
Ea: activation energy
R: ideal gas constant
T: absolute temperature (125°C + 273 = 398 K)
For the uncatalized reaction,
For the catalized reaction,
The ratio kC to kU is 6.0 × 10⁻⁸A/3.4 × 10⁻¹³A = 1.8 × 10⁵

Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
