Answer:
The events in chronological order are:
- Abrin is absorbed into the blood and enters the body's cells
- Abrin binds to ribosomes in the cytoplasm
- Abrin inactivates the 28S rRNA in the large subunit of the ribosome.
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- Victim dies
Explanation:
Abrin is a toxic protein obtained from the seeds of Abrus precatorius, it is highly toxic, with an estimated human fatal dose of 0.1-1 microgram/kg, and causes death after accidental and intentional poisoning.
When ingested the abrin would enter the victim's body and travel through the blood and eventually enter a cell's cytoplasm (abrin is absorbed into the blood and enters the body's cells). Once there it would interact with the ribosomes and reacts with them on a molecular level (peptide bond catalytic enzyme) (abrin binds to ribosomes in the cytoplasm), which results in the ribosome exhibiting its toxic response to abrin (abrin inactivates the 28S rRNA in the large subunit of the ribosome). As a result of the ribosome reacting to abrin (ribosomes are unable to add new amino acids to polypeptides), protein synthesis within that cell is affected (protein synthesis halts in many tissues). Once multiple cells are affected by abrin the organ will exhibit its toxic response (multiple organ systems fail), and the victim would die.
Answer:
The most obvious one is that asexual reproduction is where an organism gives birth by itself. Normal reproduction includes two organisms mating.
I know nothing else.
Protein kinases are located on the plasma membrane as integral or peripheral membrane protein so that they can more readily encounter and phosphorylate other membranes proteins.
These protein are embedded in the phospholipid layer to perform the function of plasma membrane that mainly include the selective transport of molecules and cell - cell recognition.
The plasma membrane perform the function to provide protection for cell. It differentiate between the outside and inside of the cell.
Phospholipid is the lipid membrane that usually consist of lipid bilayers. It act as barrier to protect the cell against environmental issues.

Explanation:
Non-renewable energy sources are not just altering our Earth's atmosphere by increasing the amount of greenhouse gas emissions. They also emit a variety of pollutants that affect people's health and the environment. ... When mercury is emitted into the air, it deposits on the ground or in water.
