The evolution of wings and the ability to move by flying is a unique adaptation of insects among all protostomes. During the pre-adaptation, their wings might held the respiratory structures for greater exchange of gases or it function as a protective shields over their leg joints.

Moreover, like dragonflies that are unable to tuck their wings when at rest, the next evolutionary burst is the foldable wings they have. These insects includes locusts and stoneflies.

I think it is the ability to move by flying. Protostomes are one of the two groups of animals having a true body cavity (coelom) and are believed to share a common ancestor. They include the mollusks, annelids, and arthropods. In this animals the blastopore becomes the mouth. Other characteristics include, they have true tissues, they have bilateral symmetry, and that the mouth develop before the anus in during embryonic development.

Water has special characteristics because of the nature of hydrogen bonds what are they?

Amanda [17]

Water has special characteristics because liquid water is denser than ice and ice floats on top of liquid water.

Answer: Option A & D

<u>Explanation:</u>

A water molecule is formed by the covalent bonding between two atoms of Hydrogen atom with one atom of Oxygen. In water, the Hydrogen bonds are the one that keeps the water molecule intact.

When the water molecule freezes the bonding becomes weak as they are separated and set apart which makes the liquid water denser than ice. Normally a substance floats if it is less dense. Ice floats because it is less dense than water.

What you have to bear in mind is to make the compound charged, in order that it will be soluble in water than in ether. You should make the pH basic for acid as in the salt compound in order to cause the acid to dissolve in the water layer.<span> </span>
