Answer:

A

Explanation:

A: Venus rotates far more slowly than Earth

Look at the column that says Period of Rotation.

Venus has a rotation period of 243 days.

Earth has a rotation period of about 24 hours.

243 days is much longer than 24 hours, so this is true.

B: Venus's year is longer than Earth's.

The year is also another way to say Period of Revolution.

Venus's is about 224 days.

Earth's is about 365 days.

Venus's is actually shorter, so this is false.

C: Mercury is approximately twice the size of Earth.

Let's look at the Equatorial Diameter column.

Mercury's is 4,880 km.

Earth's is 12,756 km.

Mercury's is much smaller than Earth's, so this is false.

D: All of the above.

Since B and C are both not true, this is incorrect.

Therefore, the correct answer is A: Venus rotates far more slowly than Earth.

The noncyclic pathway is a FLOW of electrons from water, to photosystem II, to PHOTOSYSTEM I to NADPH. Energy is released  as  ELECTRONS  move through the first electron transfer chain. This energy pumps HYDROGEN IONS  into the thylakoid compartment, and then they power the formation of ATP as they flow back out. Sunlight provides the energy needed to keep this cycle going.

----------------------------------------------------------------------------------------------------

  1. Luminous energy is trapped by chlorophyll in Photosystem II.
  2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.
  3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.
  4. <em>When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules. </em>
  5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.
  6. <em>When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II. </em>
  7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.
  8. The released energy is used to produce ATP molecules.
  9. Hydrogen ions go back from the stroma to the thylakoid compartment.

The final products are oxygen, ATP, and NADPH.
