Homeostatic receptors are the structures that provide information about conditions in the internal environment in living organisms. They help regulate physiological processes to maintain a stable internal environment.
well, Amoebas do not have a backbone. which makes them a invertabrate.
Complex organisms evolved from simple organisms, so simple organisms evolved first.
Some examples of organisms that reproduce internally include mammals, birds, insects, and some reptiles. These organisms typically have specialized reproductive structures, such as reproductive organs or egg sacs, that allow for internal fertilization and development of offspring before birth or hatching.
Integumentary system covers both internal and external body structures.

Homeostatic receptors are the structures that provide information about conditions in the internal environment in living organisms. They help regulate physiological processes to maintain a stable internal environment.
Examples of internal structures that enable organisms to survive in their environment include specialized organs such as gills for underwater respiration in fish, air sacs in birds for efficient oxygen exchange, and specialized digestive systems like rumens in ruminant animals to digest cellulose. These structures are adapted to meet the specific challenges of the organism's environment and help ensure their survival.
Electron microscopes should not be used on living organisms to study their internal structures because the high-energy electron beams can damage or kill the cells. This can lead to inaccurate results and harm the organism being studied. Instead, other non-invasive imaging techniques should be used to study living organisms.
The integumentary system protects and covers internal structures.

Organisms that lack a cell wall, such as animals, usually have an internal skeleton made of bones or cartilage to provide support and protection. This skeletal system allows for movement and helps maintain the overall structure of the organism. Additionally, some cells in these organisms may have cytoskeleton structures like microtubules and actin filaments that provide internal support.

They are very different organisms. Their internal structures are not at all alike. Hummingbirds are vertebrates like us, with internal skeletons, muscles and organs. Butterflies are insects, with their hard parts on the outside.
