<em>It is advantageous to have lesser number of bones in the pectoral girdle.</em>
<u>Explanation:</u>
Pectoral girdle is made up by the bones that connect the upper limbs to the appendicular skeleton which includes all the limb bones. Pectoral girdle in humans is made up of two bones. They are clavicle (collar bone) and scapula. The pectoral girdle allows the free movement of upper limbs.
The bones of pectoral girdle are not as massive as the bones of pelvic girdle since it doesn’t have the function of support. Lesser number of bones in pectoral girdle makes movement of upper limbs more free.
Answer:
Patrick's hypothesis was "If fish eat microwaved food, then they will swim faster through the maze."
The fish that are in the control group are the fish without microwaved food.
The independent variable is the microwaved food.
The dependent variable was the time it took for the fish to swim through the maze.
Patrick's conclusion should be that the special food did not seem to make a large difference in helping the fish become faster, since 8 out of 10 fish were faster in both special food and regular food groups.

Friction is a force resisting the movement between 2 objects. (slows or stops the movement)
