B. a toaster being used to toast bread

D. a car horn honking

From the examples given in this question, the following are examples of scenarios that involve energy transformation:

- A lamp being turned on: This converts chemical energy to light energy.

- A toaster being used to toast bread: This converts electrical energy to heat energy.

- A car horn honking: This converts electrical energy to sound energy.

Note that, melting of a chocolate does not transform any form of energy.

tekilochka [14]

Answer:

<u>Option-</u>

  • As many believe after doing an extensive form of research work of years that reptiles are the ancestors of the mammals that we see now. Which means that we mammals evolved from the pre-historic form of reptiles.                                                                            

Explanation:

  • Fossils of Thrinaxodon, a species that lived during the Triassic period, have been found in both South Africa and Antarctica. Thrinaxodon had a reptile-like skeleton and laid eggs, but small depressions on the front of its skull suggest it had whiskers and, therefore, fur. Thrinaxodon may have been warm-blooded. The fossils of Thrinaxodon are consistent with the hypothesis that <u>mammals evolved from the pre-historic reptiles.</u>
