Two types of locomotion. | Sessile and motile. |
Sessile. | Stationary, remains in place. (Ex: plants, barnacles, corals) |
Motile. | Able to move. (Ex: humans, reptiles, amphibians) |
True or False: Sessile organisms have an advantage over motile organisms. | False, motile organisms have an advantage over sessile organisms. |
Advantages motile organisms have over sessile organisms. | They can obtain food, escape predators, can find mates and shelter. |

Four types of joints. | Ball and socket, hinge, pivot, and gliding. |
Type of connective tissue in bone. | Collagen. |
Flexible, fibrous, and elastic tissue. | Cartilage. |
Function of cartilage. | Provides flexibility between joints, as well as cushioning against impact and pressure. |
