List the 4 abiotic forms of nitrogen cycle and the chemical formula
weeeeeb [17]

Answer:

Four abiotic forms of nitrogen cycle and its chemical formula

Ammonium – NH^{4+}

Ammonia – NH^3

Nitrite – NO^2

Nitrate – NO^3

Explanation:

Ammonium: In the nitrogen cycle ammonium is starting point that is present in soil and are converted to various forms by different process.

Ammonia: In the process of nitrogen fixation, the bacteria having nitrogenase enzymes reacts with the nitrogen as well as hydrogen and produces the ammonia, which is further converted to organic compounds.

Nitrite: The nitrosomonas bacteria present helps in conversion of nitrogen gas into nitrite.

Nitrate: Again the Nitrite is converted into Nitrate by the nitrobacter. During the process of assimilation ammonium and nitrate are absorbed by the plants.

quizlet chromosomes are composed of: please choose the correct answer from the following choices, and then select the submit ans
Anna11 [10]

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;

\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or}    & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \  membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}

Explanation:

Prokaryotic cells

The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells

Eukaryotic cells

Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
