|
|
Name the 3 domains. |
Archaea, Bacteria, Eukarya |
|
|
What is the characteristic of Archaea? |
Microscopic Unicellular Prokaryotic Lack a nucleus Live all over the world Shaped like sticks, balls, triangles, and squares |
|
|
What is the characteristic of bacteria? |
Microscopic Unicellular Prokaryotic Lack a nuclues Live all over the world Shaped like sticks, balls, and spirals |
|
|
What is the characteristic of Eukarya? |
Cells that have a nucleus Some are microscopic Some are unicellular Most are multicellular Large enough to see with your eyes |
|
|
How does Archaea get its energy? |
They obtain energy from chemical sources and other chemicals. |
|
|
How do bacteria get energy? |
Through photosynthesis and respiration. |
|
|
How do eukarya get energy? |
From the sun or themselves |
|
|
What are the 3 groups of mammals? |
Monotreme, marsupial, and placental mammal |
|
|
What are the characteristics of monotremes? |
They lay and incubate eggs Mammary glands lack nipples No teeth Limbs attached at the sides of the body |
|
|
What are the characteristics of Marsupials? |
Blind at birth. Young completes development inside the mother's pouch. Young remains in pouch until it is able to feed and care for self. Mostly live in Austraila. |
|
|
What are the characteristics of placental mammal? |
Divided into 20 different orders. Before birth developing baby gets nourishment from the mother through the placenta. Placental mammals differ in size, shape, diet, and method of movement. |
|
|
Explain the life cycle of the frog. |
1. Eggs are laid in the water or moist area. 2. Tadpoles emerge. They attach to a plant and feed on the remaining yolk from the egg for several days. Soon they swim freely. 3. The hind legs of the frog grow first. 4. Then the forelimbs will grow. The tail is almost completely absorbed at this point. 5. Finally, metamorphosis is complete. |
|
|
How does the frog life cycle differ before and after metamorphosis? |
They begin as an egg and a tadpole and then through metamorphosis they become frogs. |
|
|
Compare crocodiles and salamanders |
Crocodiles are ectothermic, have clawed toes, hairless, carnivorous, lay eggs on land, live primarily on land, have short legs and long tails, and shed their skin as they grow. Salamanders are ectotherms, lay eggs in the water, live in water as young, breathe through gills as young, develop lungs as adults, are carnivorous, bright coloration associated with poison production to ward off predators. |
|
|
Because they are ectothermic, how do reptiles behave? |
They can often be found sitting on a rock in the sunlight. They also use shade to stay cool. |
