Technically, the definition is that autotrophs obtain carbon from inorganic sources like carbon dioxide (CO2) while heterotrophs get their reduced carbon from other organisms. Autotrophs are usually plants; they are also called "self feeders" or "primary producers".
Answer:
I would say one or more cells.
Explanation:
Unicellular organisms like bacteria contain one cell.
A multicellular organism, like us humans, contain many cells.

Answer:
patella bone
Explanation:
Although, the condyles articulate with the tibia to form the knee joint. But, Anteriorly, the smooth surfaces of the medial and lateral condyles join together to form a wide groove called the patellar surface, which provides for articulation with the patella bone. The epicondyles(a protuberance above or on the condyle) provide attachment for muscles and supporting ligaments of the knee.
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.
