Answer:

Nerve agent

Explanation:

A nerve agent is a chemical in which on exposure to humans affects the functioning of the nervous system. These chemicals are known to disrupt the process by which messages are transferred to the organs from the nerve. This disruption occurs by blocking the activity of acetylcholinesterase, which is responsible for the catabolism of a neurotransmitter, acetylcholine.  

On exposure to a nerve agent, the muscles of the body become paralyzed and early symptoms is production of excess mucous such as in runny nose, pupil constriction and also difficulty in breathing.

These agents are sometimes used in chemical warfare. Examples include sarin, tabun etc.

The blood circulation is increased which is involved in the enhancement of the acute immunity of the person.

A researcher incubates a cell with radiolabeled amino acids. These amino acids are incorporated into the proteins as they are sy
AURORKA [14]

Answer:

The incorporation of radiolabeled amino acids during protein synthesis occurs when the data shows the organelles involved with protein synthesis, packaging and transport, that is, radioactivity levels would increase first at the rough endoplasmic reticulum, followed by the Golgi, and then the secretory vesicles (option C).

Explanation:

Protein synthesis in the cell occurs when RNA -which contains the sequence of triplets or codons that make up the genetic code- is coupled to ribosomes.

Each codon or triplet, consisting of three nucleotides, will give instructions for specific amino acids to be incorporated into the polypeptide chain that is being synthesized in the rough endoplasmic reticulum.

The Golgi apparatus is responsible for packaging or packaging the newly synthesized proteins in secretory vesicles for transport.

<em>In consecuense, </em><u><em>radioactivity levels would increase in the organelles involved in protein synthesis, packaging and transport, the rough endoplasmic reticulum, Golgi apparatus and secretory vesicles</em></u><em>, respectively.</em>
