vetebrates have backbones; while invertebrates do not
3

radial
bilateral
skeletal
asymmetrical
4
Most vertebrates reproduce sexually. Fertilization occurs in sexual reproduction when
male animal releases sperm & female animal releases eggs
part of organism breaks off & begins to grow independently
nucleus of a sperm cell fuses with the nucleus of egg cell
cells of the embryo begin to differentiate & specialize
5

it means all the DNA is located in the nuclei of the cells
all animals live on land
It eans tht all animal nodies have coeloms

producer
consumer
decomposer
scavenger
8
How do the eyes of a dragonfly help the dragonfly catch its prey?
dragonfly eyes have receptors on surface to locate the prey
nerve cells in eyes interpret the location of the prey
specialized cells in eyes send signal to bones in the wings
brain interpret signal sent by eye as image to identify prey
9
What characteristics might a fossil that was classified into the animal kingdom have?
the fossilized organism had root structures
fossilized organism had structures identified as cell walls
the fossil is of a single-celled organism
the fossilized organism had bones

sea anemone larvae have medusa body forms, but adult polyps
have a variety of coverings, including scales, skin, & fur
nerve cells carry impulses through body tortoise & chickens
