Near the Earth's surface, the sunlight that does reach the ground warms the Earth, which in turn warms the air immediately above it. So the troposphere is warmest next to the warm ground, and cooler higher up away from the warm ground.

Baking a cake
Explanation:
The reason why is because everything mixes to become one thing. so while everything was mixing and getting baked, it was chemically changing
Answer: its wrapped around the proteins, and those proteins make a nucleosome
Explanation:
Answer:
B) Nitrogen-fixing bacteria and lightning
Explanation:
Nitrogen cycle is the natural process in which atmospheric nitrogen is converted into nitrite and nitrate with the help of bacteria.
Nitrogen cycle is directly dependent on nitrogen-fixing bacteria and lightning.
As bacteria are responsible for most of the chemical conversion in the nitrogen cycle such as nitrogen fixation (first step) is done by soil bacteria (Cyanobacteria) that form ammonia, which is toxic to plants; nitrification in which ammonia is converted into nitrites and nitrates with the help of Nitrobacter and denitrification bacteria involve Pseudomonas, and Achromobacter which convert nitrite and nitrate into nitrogen.
The lightning breaks nitrogen molecules and allow it to combine with oxygen in atmosphere which further dissolve in rain and form nitrates.
Hence, the nitrogen cycle is most directly dependent upon nitrogen-fixing bacteria and lightning and the correct option is B.
