I know that It has an amniotic egg so It is either B or C
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.
Answer:
it is a catecholamine that stimulates alpha1 adrenergic receptors and, slightly, beta1 adrenergic receptors, without beta2 effect. It is the vasoconstrictor drug par excellence.
The answer is B because continental climate is the combination of both hot and cold climates. The Earth isn't only dry nor is it only polar. It is a combination of both that make up the Earth as it is today.
Answer:
B. All good choices are cancelled out by functional fixedness.
Explanation:
