Pangaea is scientifically known as the original whole mass of land that eventually was divided into separate mass entities called continents as a result to natural phenomena like earthquakes. This is more explained inthe continental drift theory. After rigorous collection of evidences, scientists noticed that fossilized plants and animals of the same species, also with the coastlines match on different continents. The answers are the first and second choices (A and B).
Answer:
Eght: 0
Explanation:
The work formula is W = F*d where d is displacement (which means the direction matters)
Same amount of work.
Eight
Time does not matter in Work. Force and Distance do.
F = 50 N
s = 0 The only work you have done is move the ball above your head. Thereafter you just held it.
t = 15 but no work is done. Tell your tired muscles that as they try and deal with holding a 5 kg mass above you head.
W = 0
Nine
Again from the last question you should be able to tell that time does not matter. The force is the same for both of you (that's why he's your identical twin).
So the work is the same. You both weigh the same. You both went the same distance.

Answer:
Electron transport produces 3 ATP molecule(s) per NADH molecule and 2 ATP molecules(s) perFADH 2 molecule.
Explanation:
The mechanism by which ATP is produced is explained by the theory of chemosmotic coupling.
This theory establishes that the synthesis of ATP in cellular respiration comes from an electrochemical gradient existing between the internal membrane and the space of the intermembrane of the mitochondria, through the use of the energy of NADH and FADH2 that have been formed by the rupture of molecules rich in energy, such as glucose.
A factory at a low elevation ships bags of popcorn to cities at high
elevations. The factory manager need to monitor the amount of air in each bag
because when the bags of popcorn are delivered into high elevation cities, it
will shrink due to the high pressure exerted by the surroundings towards the
bag. As the elevation increases, the pressure surrounding it also increases.
