Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera
