Between 1957 and 1961, thousands of expectant women in 30 different nations ingested a common antinausea drug of the time known

as thalidomide. A study of _______________ found that if the thalidomide was ingested only after day 54, then no harm occurred to the fetus, but if ingested prior to day 54 the fetus could be born with malformed or absent limbs.

Answer:

A study of <u>those newborn babies</u>

Explanation:  

Studying the infants from these pregnant women lead the researchers to find out that this drug interfered with the process of limb formation if the pregnant woman had taken this drug anytime during the 26 days critical for limb formation and development. In this way, it makes for an instance where nurture had disrupted nature.

Why is the resting membrane potential negatively charged?
Iteru [2.4K]

Explanation:

The resting membrane potential is negative due to the buildup of more sodium ions outside the cell than potassium inside.

Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential.

Further Explanation:

Neurons have unique structures which aid in facilitating communication by sending and receiving electrical signals very efficient. Parts of a neuron are separated into the

dendrites which receive messages from other neurons allowing them to pass and some of the cell body which contains typical cell components like the nucleus, endoplasmic reticulum and mitochondria.

The axon is an insulated (by the myelin sheath) tubular structure which acts as a bridge to price impulses to other neurons these also contain axon hillocks which are junctions between the axon and cell body

Synapses are junctions where axons connect to dendrites of other neurons at these junctions chemical reactions occur in order to facilitate the passage of information as chemical signals.

There are several neuron types which include sensory motor and into neurons which bridge the two.

  • The refractory period describes a period between the initiation of an action potential where Na+ channels are closed, and immediately after the action potential’s peak. Action potentials would require an influx of more positively charged ions; these must be more than a specific threshold in order to have the cells send along more action potentials which helps with figuring out stimulus intensity.
  • Potassium ions readily diffuse out of the cell more quickly than sodium due to the presence of more channels which allow for potassium leakage. The sodium pumps in neuronal membranes bring more Na+ than K+ ions into the cell; with every three sodium ions pumped out two potassium ions are brought in- this is in order to maintain the negatively charged membranes within the cell along with the resting potential
