A is a device that uses electric energy to pump thermal energy from a cooler location to a warmer location.

heat engine

Explanation:

The increase in the object's thermal energy could be a potential energy increase. Predict- suppose a beaker of water is heated from the top. Predict which is more likely to occur in the water: thermal energy transfer by conduction or convection. Thermal energy transfer by conduction is more likely to occur.

the answer to your question is sperm

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
