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: just use the explanation to help ya answer
Explanation: Well, the difference between living and non living is that Living things are tranquil cells, that chemicals to take action to stay vigorous and living means they can choose on what to do and what not to do but nonliving things are not tranquil cells and they cant effect what to choose and what not to choose such as breathing, voiding and/or reproduction
Answer:
Option B: Molecule 2
Explanation:
'Equilibrium of a molecule inside and outside a cell' means that there are similar numbers of that molecule on the inside and the outside. (hence 'equilibrium')
The number of each molecule is as follows:
Molecule 1 - Inside: 3, Outside: 5
Molecule 2 - Inside: 2, Outside: 3
Molecule 3 - Inside: 1, Outside: 5
Molecule 4 - Inside: 7, Outside: 4
Therefore the correct option is option b. 2
This is because the number of molecules inside the cell and outside the cell are the closest together, most similar out of all the molecules.
Hope this helped!
Kinetics is the study of the speed of a chemical reaction some chemical reactions are fast others are slow sometimes chemists want to speed the slow ones up and slow the fast ones down
All of these are body regions.
Antecubital, brachial, crural, and femoral regions are ventral/anterior appendicular body regions.
Axillary region is ventral/anterior axial body region.
Popliteal and sural body regions are dorsal/posterior appendicular body regions.
