3. All animals need support systems to be able to move around their respective environments.
Explain how movement is possible in human beings by referring to:
a. The different types of joints

b. The role of the endoskeleton
​

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

answer; three;
