What else can I help you with?
Are all dinosaurs reptiles?
All reptiles are diapsids. Mammals (like you and I) are, in contrast, synapsids. So in that respect all reptiles are alike. However, I would not say they were all alike. Snakes are reptiles but lack limbs. Alligators are also reptiles, as are lizards. Tuatara, gavials, amphisbaenids, and tortoises each represent one of the four main modern orders of reptiles. They share some characteristics--just as you and I do, but I would not say they were all alike.
The animal kingdom consists of organisms that?
Arthropods- bugs and crustaceans Amphibians- frogs, salamanders, and ceacilians Mollusks- sometimes have shells such as snails, others are slimy like octopuses echinoderms- pointy, includes starfish and sea urchins mammals- warmblooded and furry fish- trout, eels, sharks, etc. reptiles- turtles, snakes, lizards, alligators, etc. ringed worms- such as earthworms, parasites, and leeches birds- well, just birds
Do reptiles have lymph nodes?
No. Reptiles do not have lymph nodes as mammals do. Reptiles have lymph tissue in certain organs, particularly the spleen, but no peripheral nodes. They do have valves along the lymph perivascular areas though, sometimes called lymph "hearts", but these are not directly comparable to lymph nodes for trapping of toxins.Source: Infectious Diseases and Pathology of Reptiles By Elliott R. Jacobson"Although reptiles lack discreet lymph nodes, they do have less structured lymphoid cell aggregates within intestinal and pharyngeal mucosa."Source: Investigative Immunotoxicology By Helen Tryphonas
Do all animals have umbilical cords?
Not only humans have umbilical cord, all the mammals of the Eutheria infraclass have it, this are the placental mammals and are all the animals that give birth to a live animal but not including the marsupials such as the kangaroo, for example the human, the dog, the cow all have umbilical cord
What eats a cameleon?
Chameleons may be preyed upon by birds of prey, snakes, and certain mammals such as civets and mongooses. These predators rely on the chameleon's visible movements or lack of camouflage to detect and catch them.

Which animal lacks an amnion?
Amnions surround embryos by encasing them in amniotic fluid. Frogs are animals that lack amnions. Only reptiles and mammals have amnions.
Are bugs vertaber?
No, bugs are not vertebrates; they are invertebrates. Invertebrates lack a backbone or spinal column, and bugs, which are typically classified as insects, belong to this category. Insects have an exoskeleton and a segmented body, distinguishing them from vertebrates like mammals, birds, and reptiles.
Why are some mammals that lay eggs classified as mammals?
Monotremes lay eggs, as do reptiles. Monotremes' limbs go outward (rather than downward) from their main body, which is also true for reptiles. Monotremes lack a corpus callosum (which placental mammals have), as do reptiles. Monotremes and reptiles both have cloacas, while placental mammals have separate openings for urination and defecation. This evidence all shows monotremes to be a link between reptiles and mammals, but we now think that monotremes just evolved from an earlier branching from the mammalian tree of lineage than the marsupials and placental mammals evolved from. Monotremes are not a link between reptiles and mammals.
How do the eggs of birds and reptiles differ?
A reptile egg is much much much softer than birds egg.
Is a beetle is vertebrate?
No, since beetles lack a back bone they are not considered vertebrates. The small portion of species that are considered vertebrates are the ones under the Chordata phylum, they include birds, mammals, reptiles, fish and others. Beetles fall under the Arthropoda phylum with other insects, crabs, and Spiders.
How many species on earth have backbone?
Approximately 70,000 species on Earth have a backbone, known as vertebrates. This group includes mammals, birds, reptiles, amphibians, and fish. Vertebrates make up a small fraction of the total number of species on the planet, as invertebrates, which lack a backbone, are far more numerous.
Do protists have backbones?
Single celled organisms (unicellular organisms) include all archaebacteria and bacteria and some fungi (like yeasts) and some protists (like single-celled algae and protozoa). None of these organisms have a backbone, where 'backbone' is synonymous with 'spine' or 'vertebral column'. The concept of a backbone or spine or vertebral column is delimited to the realm of vertebrates (mammals, birds, reptiles, amphibians and fish). No unicellular organism can possibly have a backbone.
Is it verteate or inverterrate?
The correct term is "invertebrate," which refers to animals that lack a backbone, such as insects, mollusks, and crustaceans. "Vertebrate," on the other hand, denotes animals with a backbone, including mammals, birds, reptiles, amphibians, and fish. Both terms are used in biology to classify different groups of animals based on their anatomical features.
Do fish have a diaphragm?
Muscles in the frog's throat push air to the lungs by a process called buccal pumping. This is compared to the diaphragm of humans.I hope this helped.
Is an peruvian fire stick an vertabrate?
No, a Peruvian fire stick, also known as the Peruvian firestick or the Peruvian walking stick (scientific name: Deilephila elpenor), is not a vertebrate. It is an insect belonging to the family Sphingidae, which includes hawk moths. Insects are invertebrates, meaning they lack a backbone, unlike vertebrates such as mammals, birds, reptiles, amphibians, and fish.
