The advantage for the reduced gametophytes in seed plant is that they gain nutrients from the sporophytes
Gametophytes are microscopic and have capacity to develop from spores retained in the sporangia of parental sporophyte. This kind of arrangement protect developing gametophyte from environment stress which enable it to gain nutrient from sporophyte.
Answer:
The beetles gland stores enough hydroquinone and hydrogen peroxide to allow the beetle to release its chemical spray roughly 20 times. Thus pulsed mechanism is beneficial for the beetle survival because the system uses pressure instead of muscles to eject the spray at a constant velocity, saving the beetle energy.
