The key adaption of angiosperms that allowed these plants to dominate the landscaper is flowers
<h3>What is the most important adaptation of angiosperms?</h3>
Angiosperms initially appeared in the late Cretaceous Period, between 125 and 100 million years ago.
Flowers and fruit were developed by angiosperms to draw pollinators and protect their seeds, respectively.
Flowers come in a variety of shapes, sizes, and scents that are all designed to entice pollinators.
An egg that has been fertilised grows into a seed that is protected by a fleshy fruit.
Throughout the Mesozoic period, numerous contemporary insect groups developed alongside angiosperms, including insect pollinators that supported angiosperm growth; in many cases, flowers and their pollinators coevolved.

A scientific theory changes when there is more information available about what the theory covers.
1. The given blank can be filled with vestibular nerve.
The vestibular nerve in humans conducts sensory information conducted by the vestibular hair cells situated in the utricle and the saccule, that is, the two otolith organs, and the three semicircular canals through the vestibular ganglion. It relays information to the brain about balance.
2. The correct answer is option b, that is, the vestibular sense may be capable of sensory adaptation.
The awareness of the movement and the balance of the body are controlled by the vestibular system. The vestibular senses, that is, the feelings of gravitation and movement and rotation of the body originate in the inner ear. The sense organs are the cells of the hair, which transmit signals over the auditory nerve.
