a. Tetrapods were no longer tied to the water for reproduction

Explanation:

The amniotic egg is hard-shelled and is called an amniotic egg because the embro develops within a sac called amnion.

Amphibians were first tetrapods to invade the land. The need to return to water for reproduction limited their distribution. Amniotes evolved an egg that broke the tie to freshwater.

Amniotic egg contains a series of extraembryonic membranes (Amnion, allantois, chorion, yolk sac) that, among their features , takes the aquatic environment with the egg.

Hence  a. Tetrapods were no longer tied to the water for reproductionis believed to be the most significant result of the evolution of the amniotic egg.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
