Which characteristic is not true of animals?

Answer 1

There are four key characteristics to chordates. They are the presence of a notochord, the presence of a hollow nerve cord that is dorsal to the notochord, pharyngeal pouches and an endostyle.

Answer 2

All chordates had at some stage of development a dorsal nerve cord, a notochord, and gill slits. That includes all vertebrates and certain marine animals, such as the lancelets; small, flattened marine organisms, structurally similar to the vertebrates but having a notochord rather than a true vertebral column.

Answer 3

• Animals could be either ectothermic or endothermic, but mammals are always endothermic.
• Only mammals have hairs on the skin out of all the animals.
• Only mammals have mammary glands and sweat glands out of all the animals.
• The most sophisticated heart and the circulatory system are present in mammals out of all the animals.
• Mammals have more complex living habits (e.g. human) than other animals.
• Number of mammals is only a fraction compared to the rest of the number of animals.
• Some mammals are capable of singing, but other animals are not.
