Answer: Objects have potential energy due to their position. A leaf on a tree branch has potential energy. The leaf's energy can be turned into motion as it falls.
Explanation:
Dogs can regulate their body temperature by the time they are 7 weeks old.
Dogs have remarkable internal mechanisms that maintain their body at the proper temperature at all times, irrespective of the air temperature because they are unable to endure large changes in their body temperatures.
Dogs do not perspire through the skin as people do due to their insulating coats.
A comfortable winter temperature for most dogs is between 68 and 72 degrees. The same considerations mentioned above for selecting a safe, comfortable summer temperature setting apply to selecting a winter thermostat setting.

Answer:C
Explanation:
Resting Membrane Potential (RMP) is the charge difference represented as voltage difference across a nueronal cell membrane at rest.
It has a value of -50 and -75mV.
Graphically it represents the flat plateau at the last part of the curve of action potential (check the attachments)
In a normal resting cell after Action potential ;for example nuerone,the intercellular layer has more potassium ions, while the extracellular layer has more Sodium ions .
These ions have special channels called sodium and potassium channels for movement in and out of these ions by active transports.
The movements of these ions across the membranes generated electrical potential difference for action potential.
Answer:
The answer is C, persistence.
