erastovalidia [21]
<h2>Answer is option "E"</h2>

Explanation:

  • Enzymes belong to the proteins category because enzymes are long chains of amino acids bound together by peptide bonds
  • Enzymes have a special marker on them called an active site that, like a puzzle piece, fits with only one other type of molecule, generally referred to as a substrate. The substrate is a molecule that will undergo a reaction that results in it splitting into two separate molecules, called products
  • The substrate-specific to a particular enzyme will bind at the active site, forming what is known as an enzyme/substrate complex. In other words, a complex formed by the union of the enzyme and substrate
  • Hence, the right answer is option E "both A and B"

Put the steps of the nitrogen cycle in order, starting with the step that
Pepsi [2]

Nitrogen Cycle steps:

N molecules breaking apart via nitrogen-fixing bacteria.

Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.

The organic matter decays via decomposers

N2 is formed via denitrifying bacteria.

Explanation:

The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.

Animals (herbivores) consume the plants that have absorbed nitrogen/

When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia

The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.  

The nitrogen thus formed is released to the atmosphere

Lapatulllka [165]
I think you wrote this wrong? Is it not round rr vs wrinkled RR?? I'll answer it with that assumption:

You are crossing a rr with an RR:
You only get Rr back so they will phenotypically be all wrinkled

If you are crossing rr with an Rr (so a heterozygote wrinkled):
50% will be Rr (wrinkled)
50% will be rr (round)
