Слайд 4Chordates
What is a chordate?
1. Has either a backbone or a
notochord (vertebrate)
2. Can either be an ectotherm or an
endotherm3. Only 4-5% of animals are chordates

Endotherm (warmblooded)
Has a stable body temperature
Ectotherm (coldblooded)
Can change body temperature
due to the environment

Слайд 7Keyterms
Backbone is the bone on back side of the body
Arthropods
have segmented body, jointed limbs and exoskeleton
Chordates is any animal
that has a spinal cord
Слайд 8Molting
The same way as we change the size of
clothes when we grow, arthropods change their exoskeletons too. Their
exoskeletons is hard and do not grow, a new soft axoskeleton is formed under their old one. Then they crack and leave old exoskeleton. This is known as molting.
