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.
Without enzymes, the temperature inside cells would increase rapidly.
Without enzymes, biochemical reactions would cease completely.
Without enzymes, chemical reactions would not occur quickly enough to sustain life.
Without enzymes, ribosomes would break down proteins, rather than build them.
They have different genes.
This is a question that you would have to answer
for example: i found a small and colorless bear looking animal(sight). When i touched it was fuzzy and soft(touch). It smelled like dirt and lavender(smell). The creature was sleeping and it was breathing slowly(hearing). I took one of its hair’s and it was like human hair(taste)
BUT REMEMBER since it’s a species it could be an animal or human or a plant.
hopefully I could help!!
Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
