Answer:
When the solar winds approach the Earth, the magnetosphere (part of the Earth's natural magnetic defenses) deflects/repels most of the charged particles and shields our planet's surface from the winds. Sometimes, however, the magnetosphere isn't strong enough to block the Earth from these winds, so they do hit Earth and may cause catastrophic consequences, such as ruin power grids, cut off telecommunications (cell service/calls), etc.
Hope this helps you out! Have a nice day! :)
Answer:Sea Otter and hark
Explanation:
Answer:
27 min
Explanation:
By the Michaelis-Menten Kinetics Model, the initial velocity of the enzymatic reaction is given by:
where vmax is the maximum velocity, [S] is the substrate concentration and Km is the equilibrium constant. The maximum velocity is directly proportional to the enzyme concentration.
So, for 12μmol of the product formed in 9 min, the velocity is also:
v0 = 12/9 = 1.33 μmol/min
For [S] 1,000 times higher then Km, Km can be unconsidered in the equation, so:
v0 = vmax
vmax = 1.33 μmol/min
If the enzyme concentration decreases by three, the maximum velocity will also decrease by three, so it will be: 0.443μmol/min. Km continues the same, and [S] will be multiplied by 2, so Km can still be unconsidered. So:
v0 = vmax
v0 = 0.443 μmol/min
Then,
0.443 = 12/t
t = 12/0.443
t = 27 min
1. Because of the Ozone Layer.
2. Put on Sunscreen.
The moles of oxygen produced is calculated as follows
write a balanced reacting equation, that is
Mg(ClO3)2 ---->MgCl2 + 3O2
from the equation above the reacting ratio of Mg(ClO3)2 to O2 is 1: 3 therefore the moles of O2 produced = 5.12 moles x3 =15.36 moles
