Answer:
The correct answer is - urea.
Explanation:
In our body, to produce energy or produce glucose our body breaks the amino acids, it gets from proteins mainly. These amino acids are mainly breakdown into amine groups.
The human body has a unique ability to pack ammonia(amine group) by converting it to urea and incorporated and produced by the liver using 2 molecules of ammonia (NH3) and 1 molecule of carbon dioxide (CO2). This incorporated urea is then secreted from the liver and incorporated into the urine in the kidney for further process.
thymine
adenine
cytosine
guanine
Explanation:
uracil is not because uracil is only RNA.

stay safe
brainliest is appreciated only 1more to level up please help :)))
Acylhomoserine lactones used in quorum sensing regulate their own synthesis by an autoinduction system.
- Numerous bacteria use acyl homoserine lactones (acyl-HSLs), significant intercellular signaling molecules, to track the density of their population for quorum-sensing control of gene expression. The LuxI family of proteins produces the signals in question.
- A lot of proteobacteria use quorum-sensing signals from acyl-homoserine lactones.
- Cells create a baseline amount of signal at low population densities, and when enough signal has accumulated in the environment, it binds to its receptor and activates quorum-sensing-dependent genes.
