Answer:

D) its moon Charon is over half the diameter of Pluto

Explanation:

Charon is the largest of Pluto's five moons and has more than half the diameter of Pluto. For many years scientists believed that this moon was a large, monotonous ball of craters. Until July 2015, when the New Horizons spacecraft went “only” 29,000 kilometers from the satellite and revealed a landscape covered with giant mountains, huge canyons, a strange polar cap, surface color variations and landslides.

High-resolution images of Charon's hemisphere facing Pluto showed a belt of fractures and canyons that span more than 1,600 kilometers across Charon's face. Four times longer than the Grand Canyon, and twice as deep, these faults and cannons indicate a titanic geological twist in the satellite's past.

The nitrogen cycle _________.
Alecsey [184]

Answer:

D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.

Explanation:

The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).

The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.

Hence, the correct option is D.
