can reptiles control their body temperature by burning calories inside themselves- using their metabolism?
NO - reptiles cannot use fuel to adjust body temperature - they must bask in the sun or hide in the shade, etc.
reptiles: land vertebrates with dry skin, claws, and an amniotic egg that can be layed on land
small group of unusual lizards in New Zealand like the tuatara - they have a pineal 'eye'
the "little brain" attached to the rear of the brainstem; it helps coordinate voluntary movement and balance
mammals that feed and carry the young in a pouch on the mother (the marsupium); it contains the teats which supply milk to the young
an animal in the early stages of development - becomes the fetus in more complex vertebrates, becomes the larvae in lower vertebrates (human embryos become fetuses, frog fetuses become tadpoles)
organ in placental mammals through which nutrients, oxygen, carbon dioxide, and wastes are exchanged between embryo and mother - made of both fetal and maternal tissues
pointed teeth that grip, puncture, and tear meat (especially useful in capturing and killing prey)
used for crushing, mashing and grinding - side teeth in your mouth in front of the molars
Reptiles reproduce by internal fertilization -
- True - in order to fertilize the egg before the shell is formed, fertilization must be internal
Are reptiles mostly viviparous?
- NO- reptiles cannot keep the developing embryo fed inside the mother because the shell prevents that
a pouch in many birds and some lower animals before the stomach; used for storing and moistening food
What makes a bird's respiratory system so efficient?
Airflow one-way - so the air in the lungs isn't a mixture of inhaled breath and air about to be exhaled. The bird exhales air through a whole separate tube.
What is the benefit of a four-chamber heart compared to a three chamber heart?
Four chambers allows the heart to keep oxygen-rich blood completely separate from oxygen-poor blood.
warm-blooded vertebrates descended from reptiles, some (the carnivorous ones) were ancestors of birds; most of the later carnivorous dinosaurs had feathers while the majority of the herbivores had none
stomach chamber in cows and related animals in which newly swallowed plant food is stored and processed
order of mammals whose predominant teeth are canines for tearing; includes lions, tigers, bears, foxes, wolves, dogs, cats, raccoons, seals, and walruses
