True or false the consumption of irradiated food during pregnancy can cause birth defects
guajiro [1.7K]

Consumption of irradiated food during pregnancy can cause birth defects is false.

<h3>What are birth defects?</h3>

Birth defect in pregnancy are the structural or functional abnormalities occur during intrauterine stage. It can be detected either prenatally or in infancy state.

The primary causes are genetic, Socioeconomic, Environmental and other factors.

Chromosomal abnormalities and single gene defects are the major genetic abnormality based birth defects, such as Down syndrome and cystic fibrosis etc.

When parents are related by their blood group can also leads to high risk of rare  genetic birth defects.

Hence, the statement is false

An action potential involves potassium ions moving ________ the cell and sodium ions moving ________ the cell.
Alecsey [184]

An action potential involves potassium ions moving <u>outside </u>the cell and sodium ions moving <u>inside </u>the cell.

<h3>how does it action potential work?</h3>

Neurons have a negative concentration gradient most of the time, meaning there are more positively charged ions outside than inside the cell. This regular state of a negative concentration gradient is called resting membrane potential. During the resting membrane potential there are:

  • more sodium ions (Na^+ ) outside than inside the neuron
  • more potassium ions (K^+ ) inside than outside the neuron

The concentration of ions isn’t static though! Ions are flowing in and out of the neuron constantly as the ions try to equalize their concentrations. The cell however maintains a fairly consistent negative concentration gradient (between -40 to -90 millivolts). How?

  • The neuron cell membrane is super permeable to potassium ions, and so lots of potassium leaks out of the neuron through potassium leakage channels (holes in the cell wall).
  • The neuron cell membrane is partially permeable to sodium ions, so sodium atoms slowly leak into the neuron through sodium leakage channels.
  • The cell wants to maintain a negative resting membrane potential, so it has a pump that pumps potassium back into the cell and pumps sodium out of the cell at the same time.
