A Hydrostatic Skeleton vs. Body Skeleton: What Makes Them Different?
How are a hydrostatic skeleton and a body skeleton similar and different?
a) They both provide support, but a hydrostatic skeleton uses fluids while a body skeleton uses bones. b) They both rely on muscles for movement, but a hydrostatic skeleton is found in invertebrates while a body skeleton is found in vertebrates. c) They both protect internal organs, but a hydrostatic skeleton is found in mammals while a body skeleton is found in fish. d) They both store minerals, but a hydrostatic skeleton is found in plants while a body skeleton is found in animals. Final answer:
A hydrostatic skeleton and a body skeleton are similar in providing support, but differ in structure and location. Hydrostatic skeletons are found in invertebrates, while body skeletons are found in vertebrates. option b is correct.
Answer:
Option b is correct. A hydrostatic skeleton and a body skeleton are similar in that they both provide support to organisms, but they differ in their structure and function. A hydrostatic skeleton is formed by a fluid-filled compartment within the body, while a body skeleton is made up of bones. The hydrostatic skeleton is found in invertebrates, such as sea anemones and earthworms, while the body skeleton is found in vertebrates, including humans and horses.
Detail Explanation:
A hydrostatic skeleton is a fluid-filled structure found in many invertebrates that provides support for the organism's body. This type of skeleton relies on the pressure of the fluid to maintain its shape and allow for movement. In contrast, a body skeleton, also known as an endoskeleton, is made up of bones and cartilage in vertebrates, serving as a rigid framework for muscles to attach to and enabling movement.
The main difference between a hydrostatic skeleton and a body skeleton lies in their composition and location within the animal's body. Invertebrates like jellyfish and worms have hydrostatic skeletons that allow them to move through water and burrow underground efficiently. On the other hand, vertebrates like mammals and reptiles have body skeletons that provide structural support and protect internal organs.
It's fascinating to see how different organisms have evolved unique skeletal systems to suit their lifestyles and survival needs. Understanding the differences between a hydrostatic skeleton and a body skeleton helps us appreciate the diversity of life on Earth and the incredible adaptations that have occurred over millions of years.
