A possible explanation to a question or a problem is the:

Structure 1 is the :

Which describes the net movement of a solute from a high solute concentration to a low solute concentration with the help of a transport protein?

The polymerase chain reaction (PCR) joins many small DNA molecules into a long chain.

Structure 2 (which is not pointing at the dot) is the:

Modern birds still carry some of the features of their ancestors, the dinosaurs. This is an example of which characteristic of living organisms:
