Are birds and bats more closely related ...

Are birds and bats more closely related to each other than to sauirrels or lizards?

Text Solution

Verified by Experts

1. No, bats are mammals whereas birds belong to aves.
2. Squirrels are mammals and lizards are reptiles.
3. So bats are more closely related to squirrels and lizard than birds.
4. But bats ad bird resemble mor as they have wings
5. These wings are structurally different but functionally similar formed to have a common use of flying.
6 but their origin is not common, so not losely related.
7. these type of organs are called analogous organs
8 . This type of evolution is called convergent evolution.

The necessary condition for a molecule to exhibit optical isomerism is dissymmetry or chiral. Thus all organic compounds which contain one as symetric carbon atom are chiral and exist in two stereoisomers. Although the two forms have the same structure, they have different arrangements of groups about the as symmetric carbon. In fact, they represent as symetric molecules. They do not have a plane of symmetry. They are related to each other as an object to its mirror image and are non superimposable. The two structures actually stand for dextro or (+) and leavo or (-) isomers. Since they are related each other as mirror images, they are commonly called enantiomers. Which of the following statements is correct regarding compounds I to III
