Answer: The correct answer is -

B) NADH and FADH2.

NADH and FADH2 are electron carriers that provide electrons, which move across four protein complex (Complex I to complex IV) in the inner mitochondrial membrane.

These are high energy electrons and ultimately help in the generation of large amount of energy in the form of ATP.

The flow of electrons across protein complex leads to change in shape their shapes, due to which protons are pumped across the inner membrane ( that is from mitochondrial matrix to the intermembrane space).

As a result, a concentration gradient of Hydrogen ions is formed across the membrane.

By diffusion, the hydrogen ions travel back through a special channel called ATP sythase. This channel utilizes the energy of the flow of the Hydrogen ions to form ATP.

Bond [772]

Answer:

Flowers

Explanation:

Angiosperms are plants that have flowers as their specialized reproductive organs. The flowers will give rise to seeds enclosed within an ovary.

The main reproductive parts are the stamen and pistil.

The stamen is the male part and it is made up of the anthers which produces pollen and the filament that holds the anthers in position.

The pistil on the other hand is the female reproductive part composed of ovary stigma and style.

The in the ovary is where the ovules are produced.

How do natural geologic processes such as, weathering, erosion, plate tectonics, sub-surface heat and material flow, contribute
irina [24]

Explanation:

The earth is a dynamic planet. Different geologic processes are at work constant shaping and configuring the earth.

Natural geologic processes are divided broadly into surface and internal processes.

The surface processes are the weathering and erosion driven by the sun.

Internal processes are the plate tectonics, sub-surface heat and material flow.

  • These processes are continuously interacting and changing the earth surface.
  • The earth has evolved through many phases as a result of these processes.
  • Plate tectonics at one end through constructive processes brings in new materials to the earth. At another end, the materials are destroyed.
  • Weathering and erosion causes the lowering of the earth surface formation of sedimentary rocks.
  • The exchange of heat and matter driven by this process has been in play for a long time and this has sculpted the surface of the earth.
