Answer:
C
Explanation:
The Brain is located in the head and is the hub of the entire nervous system
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:
Before leaving : loss of property, loss of means of livelihood/job, extreme fear, Malnutrition due to Famine
In their new home : Torture , robbery and betrayal, and Harsh environmental conditions, loss of family member in transit
Explanation:
The stressors experienced by refugees before leaving their country of Origin can be categorized into ( 2 )( i.e. physiological and psychological ). examples of such stressors are ; loss of property, loss of means of livelihood/job, extreme fear, Malnutrition due to Famine. while some of the stressors that might be experienced by refugees in their new home includes; Torture , robbery and betrayal, and Harsh environmental conditions.
The General adaptation syndrome is a series of reactions ( physiologic ) which causes a change in the equilibrium of a body system ( human ) in response to stressors ( i.e. stressors experienced by the refugees ) as regards the question above. once the stressors is dealt with by the body the equilibrium of the body system is been restored
Answer: d. Progestrone
Explanation:
A progestrone is a hormone which inhibits the contraction of the uterine muscles and also develops and maintains the lining of the uterus so as to support the development of the fetus till the period of delivery or child birth.
