Answer:
The correct answer is explained below:
Explanation:
- Flooding and intrusion of salt water in the low lying areas can adversely affect human life. This can happen in the following ways:
- Flooding can cause many people to die due to drowning in the flood water.
- Many people lose their habitat and all their belongings due to the entry of water into the settlements having only the ground floors. These people need to rehabilitated to safer regions.
- The saline water percolates through the ground and mixes with the fresh water present in the water table, thereby making them saline and non-consumable.
- People have to face the dearth of food, drinking water, clothes and electricity until rescue operations are sent.
- Increased chance of transmission of water-communicable or water-borne diseases like diarrhoea.
The phospholipid bilayer functions mainly as a structural framework for the membrane where the polar heads of the phospholipids tend to orient towards their polar surroundings, preserving the hydrophobic part from any contact with water.
<h3>What are phospholipids?</h3>
They are lipid molecules that have a strongly polar group in addition to the hydrophobic hydrocarbon chain.
<h3>Characteristics of phospholipids</h3>
- The polar heads are oriented towards the aqueous medium (intra and extracellular).
- The hydrophobic tails tend to be oriented towards the lipid medium, that is, inside the bilayer, constituting the membrane matrix.
Therefore, we can conclude that phospholipids, due to their amphipathic nature, tend to orient or organize themselves spontaneously, forming the so-called lipid bilayer.
