Answer:
The chemical reaction is: AB + CD ---> AC + BD (ΔH= - )
Explanation:
After the reaction between two reactants, two products are generated.
As the products have less energy than the reactants, this energy is released and ΔH is negative
Some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as:<u> vestigial structures</u>.
Vestigial structures are organic structures that do not appear to fulfill any important biological function in the organism that possesses them.
- These structures are preserved as an inheritance of the evolutionary process, because at some point in the history of evolution an ancestor of the current species had that structure.
- These types of structures, which can be bones, organs, structures in the skin or any other part of the body, no longer offer any meaningful function for the body.
- The presence of vestigial structures in animals is considered proof that evolution and natural selection exists.
Therefore, we can conclude that some fossil snakes have remnants of hip bones and legs even though these animals had no legs. These remnant structures are best described as vestigial structures.
