Final answer:
Dinosaur weight estimates based on scale models are not always accurate or reliable due to several factors.
Step-by-step explanation:
False. Dinosaur weight estimates based on scale models are not only as accurate as the models. There are several reasons why the weight estimates may not be accurate. For example, the model may not be able to incorporate DNA evidence (a). Additionally, the model may be based on analogous traits without considering evolutionary relationships (b). The model may also not be experimentally verified (c) and may not consider the possibility of gene transfer between unrelated species (d). Therefore, the accuracy of dinosaur weight estimates based on scale models is dependent on various factors and may not always be accurate or reliable.
