Q6: A
Q7:D
Q8:C

Reasoning
Q6: Based on all the other questions talking about common ancestors I deduced that to find a “common” ancestor they need to find things that are the same.

Q7: All arthropod have a exo skeleton for example a lobster or crab. They all have a head, abdomen and thorax for example ants. They all have legs with joints for example a spider.

RUDIKE [14]

Answer:

patella bone

Explanation:

Although, the condyles articulate with the tibia to form the knee joint.

Posteriorly, the medial and lateral condyles are separated by a deep depression called the intercondylar fossa.  The combination of the medial and lateral condyles with the patellar surface gives rise to  the distal end of the femur a horseshoe (U) shape.
