Adenosine Triphosphate Living organisms store chemical energy in the form of biomolecules. Organisms transform these biomolecules to other forms of energy when needed. For example, chemical energy is transformed into mechanical energy when a muscle uses energy to move. Adenosine triphosphate (ATP) is the most important biomolecule that provides chemical energy. ATP is like a storage unit of chemical energy for the cell. It’s the most abundant energy-carrying biomolecule in cells. The structure of ATP consists of a nucleotide made of an adenine base, a ribose sugar, and three phosphate groups. ATP releases energy when the second and third phosphate molecules are broken, forming adenosine diphosphate (ADP). ADP can also form adenosine monophosphate (AMP), but this reaction releases less energy than the reaction that converts ATP to ADP.

When comparing dogs to wolves, scientists found evidence that supports the idea they come from a common ancestor. Which evidence was most important in understanding this?A comparable anatomies, fossils, and behavior
B different anatomies, similar development, and different DNA
C comparable anatomies, similar development, and similar DNA
D different anatomies, fossils, and behavior

Answers

Evolution overs over time such that the best traits are being passed on from successive generations in every species or populations. We can compare these different species from a common ancestor. Evidences include fossil evidence, genetic evidence, comparative anatomy and more. These are usually shown in phylogenetic trees. Most apparent differences between wolves and dogs are their anatomy or morphology. Fossils support these. Behavior between them are different especially in terms of mental differences.

Best answer is A. 

Answer:

C. Comparable anatomies, similar development, and similar DNA
