Dr. digger, a paleontologist, finds a fossil that he describes in his journal. the creature was approximately 1 meter long, with its backbone fused into a large shell covering the body cavity. it had a beaklike mouth, without teeth, and all four limbs were in the form of flippers. based on anatomical similarities, to which modern animal is dr. digger’s creature most closely related?
a. zebra
b. bony fish
c. sea turtle
d. snake

Ans.

The fossil found by Dr. Digger was about 1 meter long, with backbone, body cavity covered by shell, beaklike mouth with no teeth. Along with these characters, it also had four limbs that were present in the form of flippers. All these features are present in a sea turtle as sea turtle is a tetrapod, its body cavity is protected by a hard shell made up of many bones, and it has flippers that help in swimming.  

Hence, the correct answer is option 'c). sea turtle.'

explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
