Answer:
Pioneer 10 also took measurements of the gas giant's magnetosphere, radiation belts, magnetic field, atmosphere, and interior. In 1983, Pioneer 10 became the first human-made object to pass the orbit of Pluto, at that time considered the most distant planet from the sun.

Answer:
For aquatic ecosystems, these factors include light levels, water flow rate, temperature, dissolved oxygen, acidity (pH), salinity and depth. Light level is an important factor in aquatic ecosystems.
Answer:
ATP and NADPH
There are two end products of the light reaction of photosynthesis, ATP and NADPH. These molecules are produced during the cyclic and the non-cyclic photophosphorylation reactions. These are the products which are used in the dark reactions.

Answer:
Nitrogen-fixing bacteria will significantly outnumber those incapable of fixing nitrogen
Explanation:
Nitrogen-fixing bacteria are capable of growing in a medium lacking organic Nitrogen. They convert (fix) atmospheric Nitrogen (Nitrogen is abundant in air) into organic substrates. Hence, they will grow in the enrichment medium described. This is the kind of medium used to isolate nitrogen-fixing bacteria.
Non-nitrogen fixing bacteria require an organic form of Nitrogen for growth. Hence, in a medium with no nitrogen, they will rely on the Nitrogen fixers. This means delayed growth for them.
A culture medium also has limited nutrients, so the slow growers will have little or no nutrients left.
Therefore, the Nitrogen fixers will have competitive advantage and significantly outnumber those incapable fixing nitrogen.
