Explanation:
Answer:
The answer is the heat resistance of DNA and the "transformation" process.
Explanation:
The experiment showed that after inactivating the cell with heat, the DNA was intact, and through a transformation process, or what we know now as Horizontal transference of genes, the R bacteria could adapt the genetic features that allowed the S bacteria to kill the mouse.
<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
True
These factors are all causes of low birth weight in infants:
-Preterm labor
-Chronic health conditions
-Taking certain medicines to treat health conditions, like high blood pressure, epilepsy and blood clots
-Infections
-Problems with the placenta
