The amount of GPE an object has depends on its mass and its height above the Earth's surface. It is important because the weight of an object is the size of the force of gravity pulling the object down.

2. Which statement is correct about the Krebs cycle?
IRINA_888 [86]

The correct option is


a. Acetyl-CoA combines with a pyruvic acid to make glucose in the Krebs cycle.


Explanation:

The Krebs citric acid cycle happens within the mitochondrial matrix and generates a pool of energy (ATP, NADH, and FADH2) from the oxidization of pyruvate, the tip product of metabolism. Pyruvate is transported into the mitochondria and loses dioxide to make acetyl-CoA, a 2-carbon molecule.

What statement is true about earth tectonic plates
DaniilM [7]
Continent jig-saw shapes when puzzled and combined together, formed one big continent - Pangea, and was separated by drifts.

Fossil comparisons of different species were discovered into two different, separated continents in which when you combine them, they were one in the past.

Seismic, volcanic, and geothermal activity are found along imagined plate boundaries. 

Plates were actually rubbing against each other as evidence is seen on the formed mountain ranges.

A baseball fan is 150.0 m from the home plate. how much time elapses between the instant the fan sees the batter hit the ball an
Artyom0805 [142]

Approximately 0.4373 seconds

Speed of sound at 20 degree C is roughly 343 meters/second

Speed of light = 3x10^8 or 300,000,000 meters/second

at 150.0 feet away you set it up as:

150.0/343 - 150/3x10^8

150.0/343 = 0.43731778

150/3x10^8 = 5x10^-7 or 0.0000005

Subtract 0.43731778 - 0.0000005

Answer is 0.43731728

Rounding would be approx. 0.4373
