Answer: The given statement is false.
Explanation: An electric motor converts electrical energy to mechanical energy and not potential energy.
Mechanical energy is the sum of kinetic and potential energy possessed by an object. It is the energy associated due to the movement and position of an object.
An electric motor works by the process of electromagnetic induction which happens when a voltage is induced by a changing magnetic field.
Answer:
Yes.
Explanation:
Yes, all life on Earth depends on sunlight for obtaining energy and also shares a common ancestor of all organisms that lives on the land surface or in the oceans.

All the organisms have common ancestors which evolved with the passage of time when the change occurs in the environment and is responsible for the diversity of organisms.
Explanation:
The explanation for the question is in the"Hardy-Weinberg principle" pdf attached below.
The biomolecule that would be the preferred dietary intake molecule the day before a long distance runner is scheduled to compete in an event is Carbohydrates. The answer is option B.
