Answer is D. The phosphate group of membrane lipids are negatively charged.
The cell or plasma membrane is a bilayer of phospholipids. The two phospholipids layers are opposite to each other. Each phospholipid molecule consists of a phosphate group and a lipid. The phosphate form inner and outer layers of hydorphilic and are negatively charged 'heads' and lipid forms the tail, hydrophobic and non-polar. Since phosphate is negatively charged it repels negatively charged molecules and do allow them to pass through it.
Answer:
Earthquake and tsunami warning systems both monitor the same thing: seismic waves. Seismic data takes the Earth's pulse directly, so when the earth shakes, we get immediate feedback. If all goes well, we have enough time to run.
Explanation:
An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
A tsunami or tidal wave is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.
The nurse should ask the mother why she thinks so. Doing so can let the mother explain her situation which will be a good way for her to let out her feelings.
