:star: REPTILES AND AVES MASS-SPECIFIC BASAL METABOLIC RATE
:star:BACKGROUND I predict that mass-specific metabolic rate in birds (aves) are similar to reptile's mass-specific metabolic rate. My reasoning behind this hypothesis is because both species, retiles and aves, have a lot in common.
When reptiles and aves experience bad weather conditions, are worn, or growing, they shed their skin.
Keratinous scales cover the bodies of reptiles Keratinous scales cover the legs of birds.
Skulls of both birds and reptiles attach at a single point called the occipital condyle. This allows head rotation.
Both include the presence of a single middle ear bone
Birds and reptiles both produce shelled eggs, having a similar reproductive system.
Examples of the reptilia class is lizards, snakes, and turtles
Examples of Aves include owls, hummingbird, penguins, ostrich, and parrot
:star:RESULTS/DISCUSSION
The observations failed to prove the theory correct, therefore the hypothesis was rejected. Although reptiles and aves have similar characteristics, the mass-specific basal metabolic rate values differ greatly.
Reptiles and amphibians are ectotherms
Birds/Aves are endotherms
Further research had to be conducted in order to explain this large difference in number between two species with many common characteristics.
Average for Reptiles Mass-Specific Basal Metallic Rate 0.000187541
Average for Aves Mass-Specific Basal Metabolic Rate 0.042360855
An ectotherm relies on its external environment to regulate temperature of their body. Body temperature changes with the external temperature changes.
An endotherm regulates heat from the internal body and does not rely on the external environment temperature.
The mass-specific basal metabolic rate may have such a different value between Aves and Reptiles because they differ in how they regulate their body temperature.
:star:METHODS
By using Quaardvark, I clicked on the main page "Query and Report," I requested the data pertaining to the class of Reptilia and Aves.
I typed in my desired area of study, "Retilia" and "Aves"
Quaardvark: Home. [accessed 2021 Sep 22].
https://animaldiversity.ummz.umich.edu/quaardvark/
I calculated their mass-specific basal metabolic rate by dividing the species mass from the basal metabolic rate.
Link Title
I requested the average mass (g) and basal metabolic rate (W) for both the Reptilia and Ave class.
Instead of using the preset animal group, it is important to choose the group you are studying correctly before started any data recording or downloading.
:star:INTRODUCTION
Since the class Reptilia and Aves (birds) have so much in common, is it possible that their mass-specific basal metabolic rate can be almost the same value?
QUESTION/MAIN TOPIC
BACKGROUND
Reptiles and aves have similar reproductive systems, skull structures, keratinous scales, a single middle ear bone, and shedding of the skin.
