Answer:

d. chromatin

Explanation:

Chromatin is a complex of DNA, RNA, and proteins that is present in the eukaryotic cell nucleus in the form of a long, spaghetti-like filament. Histones are the main proteins that make up the chromatins.

Chromatin is usually divided into two categories according to their condition: eucromatin and heterochromatin.

  • Eucromatin: When the chromatin filaments are less condensed it means that it has active DNA, ie the cell is able to "read" the content of this genetic material.
  • Heterochromatin: The filaments are condensed, coiled together in a tangle. In this case, the DNA is inactive because cells at that time are unable to encode the condensed genetic material.

The lining of a tubular structure is referred to as the ____ .
sp2606 [1]
In biology, the inner lining of tubular structures is called a lumen.
This can refer to numerous tubular structures in the body, such as the lumen of the veins and arteries, the lumen of the intestines or the tubes in the kidneys.
This term can also be used to describe a space defined by membranes of cell organelles such as the lumen of the mitochondria, the Golgi apparatus, and others.

Since ammonia is neurotoxic to urotelic organisms, which includes humans, nitrogen atoms can be transported from tissues to the
devlian [24]

Answer:

All the above participate in the ammonia excretion

Explanation:

The amino groups present in the amino acids are required to form the urea. The ammonia disposal takes place un the liver by the urea formation and is excreted in the kidneys by urine. When free ammonia is produced in peripheral tissues, it is transported to the liver by glucose -alanine cycle, alanine in transported in the blood to the liver, where is converted into pyruvate.  

Another pathway is by glutamine synthase/glutaminase system. The storage and transport of ammonia to the liver is glutamine from glutamate by glutamine synthetase: NH3 + glutamate → glutamine once in the liver glutamine is transformed into glutamate again by glutaminase enzyme: glutamine → NH3 + glutamate.

In the liver takes place the urea cycle, the amino acids transported into the liver can be converted to aspartate. This aspartate enters the urea cycle forming an intermediate of the cycle, and the final product is urea that is excreted by urine.
