Which of the following statements about action potentials is correct?A) Action potentials for a given neuron vary in magnitude.B
MAXImum [283]

Answer:

Option-C

Explanation:

Action potential refers to the generation of electrical activity due to the influx and efflux of ions in the cell.

The cell which transmits the action potential is known as the neuron and the neuron maintains the membrane potential at -70 mv. The influx of sodium ions causes depolarization when it crosses the threshold value.  

The generated action potential now travels in the neuron through its long tubular structure called an axon.  The axon transmits the signal from the cell body towards the axon terminal and thus is known as the down the axon.

Thus, Option-C is the correct answer.

Why do you get hungry?
suter [353]

Answer:You may feel hungry frequently if your diet lacks protein, fiber, or fat, all of which promote fullness and reduce appetite. Extreme hunger is also a sign of inadequate sleep and chronic stress. Additionally, certain medications and illnesses are known to cause frequent hunger.

Explanation:

"Hunger hormones" (ghrelin) in your blood and an empty stomach signal the brain when you're hungry. Nerves in the stomach send signals to the brain that you're full, but these signals can take up to 20 minutes to communicate -- and by that time, you may have already eaten too much.

Suppose an assassin uses abrin, a translation inhibitor, to poison her victim. Place the events in chronological order, starting
mihalych1998 [28]

Answer:

The events in chronological order are:

  1. Abrin is absorbed into the blood and enters the body's cells
  2. Abrin binds to ribosomes in the cytoplasm
  3. Abrin inactivates the 28S rRNA in the large subunit of the ribosome.
  4. Ribosomes are unable to add new amino acids to polypeptides
  5. Protein synthesis halts in many tissues
  6. Multiple organ systems fail
  7. 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.
