Answer:
<u>Option-</u> "If a flock’s beak type made it easier to pick up the available food, the flock grew."
Explanation:
- We can simplify the whole answer by having argument about the structure or alignment of the birds in a given way which provides more food sources or options for the 1st generation and then the third generation can be found in a more scattered form inside the herd, as there are no more food requirement as much was before.

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.
