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.
Which group does an ant belong?
i think the ant belongs to the insect group because it has 6 legs and also did you know that an ant can carry 10 times its on wait!
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
What animals does not have vocal cords?
There are many, but giraffes are the best known
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

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.
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.
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 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.
What is the special breathing system that birds have?
The respiratory system of birds differs significantly from that found in mammals, containing unique anatomical features such as air sacs. The lungs of birds also do not have the capacity to inflate as birds lack a diaphragm and a pleural cavity. Gas exchange in birds occurs between air capillaries and blood capillaries, rather than in alveoli.
What do you do if a if a lizard hates you?
Nothing. They're reptiles. Reptiles lack the brain bits (cerebrum) that mammals have which makes them capable of complex emotions like love and hate. For reptiles it's eat/don't eat, attack/flee, and so forth. They will learn where the food comes from, and eventually learn not to bite the hand that feeds them, but they simply have no way of expressing love, hate, or anything in-between.
Why mammals suffer from lack of oxygen?
Respiration of mammals is aerobic.So O2 is essential for living.

What sound does a butterfly make?
Butterflies do not make any sounds as they lack the ability to produce vocalizations like birds or mammals. They mainly communicate using visual signals, such as their brightly colored wings and fluttering movements.
