Question
Suggest a suitable reason for the heart having four separate chambers.
✓
Answer
Human heart has four chambers that is two auricles and two ventricles. Auricles are the small chambers whereas ventricles are the bigger ones. Presence of four chambered heart serves two purposes. First, it ensures complete segregation of oxygenated and deoxygenated blood. Second, blood is received by the upper chambers and is pumped out by the lower chambers. This segregation between received blood and sent blood increases the efficiency of the heart.

X, Y, and Z are three animals. The animal X can fly but animal Y can only run on ground or walls. The forelimbs of animals X and Y have the same basic design but they are used for different purposes such as flying and running respectively. The animal Z became extinct an long time ago. The study of fossils of Z tells us that it had some features like those of X and some like those of Y. In fact, Z is said to form a connecting link in the evolutionary chain of X and Y.
- What could the animals X, Y and Z be?
- What name is given to the forelimbs like those of X and Y which have the same basic design but different functions?
- Name one feature in which Z resembled X.
- Name one feature in which Z resembled Y.
- Which is the correct evolutionary chain involving X, Y and Z : X → Z → Y or Y → Z → X?
