1: Why does Jeroen Ritsema think it’s too early to conclude that the pushing argument explains the Atlantic’s expansion? What would satisfy him that the pushing scenario might be the real answer? 2: What are some reasons why scientists might care about the movements of tectonic plates?

3: What is one practical reason why people might care about these movements? ( hint: For whom are accurate identification of positions important?)

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
