Why are sunspots dark? A) They are cooler than the surrounding gases.
B) They are areas of solid material on the sun.
C) They are warmer than the surrounding gases.
D) They are old spots on the sun.

A) They are cooler than the surrounding gases.

Explanation:

Sunspots are dark, planet-sized regions that appear on the "surface" of the Sun. Sunspots are "dark" because they are cooler than their surroundings.

A

Explanation: the gas inside the spot where the magnetic field is strongest is only emitting about 1/4 as much light as from the rest of the solar surface

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
