The chronological order of events starting from poisoning should be as follows:
- Ricin enters the victim's body
- Ricin is absorbed into the blood and enters the cells
- Ricin binds to ribosomes in the cytoplasm
- Ricin inactivates 28s rRNA in the large subunits of the ribosomes
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- The victim dies
Ricin is a plant toxin. It is poisonous to mammalian cells as it interferes with the catalytic activity of ribosomes in protein synthesis. It irreversibly binds to the ribosomal subunits and halts the polypeptide synthesis process, leading to cell death.
Note: Your question is incomplete, but probably it includes the following options:
a. Ricin is absorbed into the blood and enters the cells
b. Ricin inactivates 28s rRNA in the large subunits of the ribosomes
c. Ricin binds to ribosomes in the cytoplasm
d. Ricin enters the victim's body
e. Multiple organ systems fail
f. Protein synthesis halts in many tissues
g. The victim dies
h. Ribosomes are unable to add new amino acids to polypeptides

Answer:Who were the Familia Publica? The first recognized firefighting force organized in ancient Rome.
Explanation:
The process of how a neuron sends electrical signals to other neurons is that the sending neuron which is also referred to as a presynaptic neuron releases a chemical called a neurotransmitter which binds to a receptor on the surface of the receiving or postsynaptic neuron.
<h3>What is Neuron?</h3>
This is referred to as the structural and functional unit of the nervous system and they are responsible for the sending and receiving of signals from the brain.
A neuron sends electrical signals to other neurons by the sending neuron releasing a chemical called a neurotransmitter which then binds to a receptor on the surface of the receiving neuron.
Neurons send information very fast and is the reason why we are able to act very fast especially during emergency or dangerous situations.
