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:
The profession has grown and there are degrees that prepare budding techs to enter the field. There are also national certifying exams, which require preparation and study. As a result of all these demands, formal pharmacy technician's training is increasingly important.
Explanation:
Answer:
Parietal lobe is a part of a cortex and is located in the upper-back part of the brain.It has important job of processing sensory information. It comprehends touch, taste and temperature and integrates them. If parietal lobe is damaged, we would not be able ti taste anything.
Because there could be unseen blood mixed with the fluids. Hope this helps!!
