To solve this problem, we need to identify which organism has hollow and pneumatic long bones.$\newline$Let's analyze each option:$\newline \bullet$Neophron: This is a genus of birds, specifically vultures. Birds are known for having hollow and pneumatic bones, which help reduce body weight for flight.$\newline \bullet$Hemidactylus: This is a genus of geckos, which are reptiles. Reptiles do not have pneumatic bones.$\newline \bullet$Macropus: This is a genus that includes kangaroos, which are mammals. Mammals do not have pneumatic bones.$\newline \bullet$Ornithorhynchus: This is the genus of the platypus, a monotreme mammal. Monotremes do not have pneumatic bones.$\newline$Based on this analysis, the organism that bears hollow and pneumatic long bones is Neophron.$\newline$Therefore, the correct option is Option 1: Neophron.
