The observable characteristics that can be used to classify plants in a grassy field are leaf shape, flower color, plant height, and growth habit. These features can help identify and group different plant species based on their physical attributes.
A whale's heart typically has four chambers, similar to most mammals, including two atria and two ventricles. This heart structure allows for efficient oxygenation and circulation of blood throughout the body.
Whereas previously classification was based on homologies, that is the shared characteristics from common ancestors, modern classification is based on the following four methods:symmetrymorphologygerm layersembryonic development
Animals that have the four basic characteristics of chordates (dorsal hollow nerve cord, notochord, post-anal tail, pharyngeal slits) plus a vertebral column are known as vertebrates. Examples include mammals, birds, reptiles, amphibians, and fish.
Bovidae are a family of mammals characterized by their four-chambered stomachs and hollow horns. They typically have cloven hooves and are herbivorous. Bovids include animals like cattle, sheep, goats, and antelope.
Fish, rocks , Mammals such as whales ,and crabs.
Not all mammals have four legs. Bats are mammals, but have only two "legs." Whales and dolphins are mammals, but have no legs at all. What distinguishes mammals from other animals is not the number of legs, but the presence of sweat and milk glands.
No fish are mammals. Mammals are vertebrate animals that nurse their young. Mammals have many characteristics in common such as being warm-blooded, having some hair or fur, and being tetrapods (having four limbs, although in marine mammals these are fins).
Whales do not lay eggs, they give birth to live young.

Whales looks like fishes. They can swim in water like them but they are not fish as they respire with lugs, have four chambered heart, diaphragm, mammary gland, hairs, etc. Whales are viviparous like any other mammal.
No. Whales must to breathe air - they do not have gills and can not breathe underwater. Also, they are mammals, giving birth to live off-spring and suckling them.An easy way to distinguish most marine mammals from fish is the angle of the tail - mammals have it horizontal and fish (including sharks) have a vertical tail fin.No, whales are mammals, like dolphins. An easy way to tell is if something swims with it's tail moving side to side, it is a fish. If the tail moves up and down, it is a mammal. A whale is a mammal, it gives birth to live young and has to rise to the surface to breathe. its whale and no whales are mammals
All mammals have four legs, or at least four limbs if they're bipedal such as us, or in the case of bats. Whales have vestigial hind legs, in the form of a pelvis hidden halfway down their tail, and the flippers are their front legs. In fact, all land vertebrates (amphibians, reptiles, mammals, birds) have four limbs. ^^
Triangles have only three sides; all quadrilaterals, including parallelograms, have four.
what are four main soils used to classify soils
Oh, dude, not all mammals have four legs. Like, have you seen a kangaroo? They hop around on two legs and use their jacked-up tail for balance. And let's not forget about those sneaky dolphins, they're mammals too, but they're all about that aquatic life and don't bother with legs at all. So yeah, not all mammals are rocking the four-leg look.
There are many such features, including: 1. Mammals nourish their young with milk. 2. Mammals are warm-blooded. 3. Mammals have fur. 4. Mammals have a four-chambered heart. 5. Mammals are amniotes. 6. Mammals breathe oxygen. 7. Mammals have three middle ear bones and a neocortex. 8. Mammals have internal reproduction. Some of these characteristics are unique to mammals; others are found in some other vertebrates but not in all other vertebrates.
