Based on pages 6 & 7 the process of change over a long period of time is known as ? A - growing
B-adaptation
C-development
D-evolution

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.

if you look up in the top right corner you'll see your current profile picture, click than click "view profile" you'll be able to change it there.

geologic time scale (for gradpoint) =)
