Starfish move slow because of the material that is on the body. Also because they have a water vascular system. Water goes into the canal and they move based on that system.
Why don't you got to the beach and look at that part;)

Answer:
Explanation:
The choices provided are:
a.restaurants that use C-8-coated cookware
b.cookware manufacturers who make pans out of steel only
c.stores that sell C-8 nonstick cookware
d.individuals who use steel cookware at home
From these choices B is the correct answer.
Restaurants that use C-8 cookware will not profit from using it but will need to lose money by replacing the old C-8 coated cookware.
Stores that sell this nonstick cookware will also need to replace their inventory so they won't be making extra money, only losing it.
And individuals at home will still be using steel cookware and won't benefit or lose anything by this change with the regulations of the c-8 coated nonstick cookware.
Answer:
B. Humans will have less salmon available to eat.
Explanation:
First off, you always want to be wary of choices that are kinda extreme. Take for example, choice A., which says All of the oxygen in the atmosphere will disappear. The problem doesn't say that the plankton population will go extinct, just decrease, so oxygen from the atmosphere won't completely disappear. There are also other sources of oxygen. Moving on, C. says that the shrimp will completely disappear from the sea. This is wrong because once again, plankton won't go extinct in the problem. The shrimp population will decrease but not go extinct. Next, D. Choice D is baloney because a decrease in plankton means less food for salmon, which means the salmon would die in the area. That leaves Choice B. Choice B. makes sense because of something called the bottom-up model, which states that an increase or decrease in the amount of organisms in a lower trophic level will affect the organisms in the above trophic levels. We can see that in action here; if the amount of plankton drop, the amount of shrimp salmon will drop, which means less salmon for humans.
