Answer:
joule is its si unit
Explanation:
As a form of energy, heat has the unit joule (J) in the International System of Units (SI). However, in many applied fields in engineering the British thermal unit (BTU) and the calorie are often used. The standard unit for the rate of heat transferred is the watt (W), defined as one joule per second.
First we can look at the taxonomic order:
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
The largest level would be the one closest to the top of the list because it is the least specific and therefore the most inclusive. Out of the choices given, phylum is closest to the top, so that is the answer.
Neurotransmitters that have narcotic-like effects are called endorphins. These neurotransmitters are responsible for our feelings of excitement or satisfaction.
What is true of chemical energy is that chemical energy can be stored more efficiently as glucose than it can be as ATP. All the other answers in this case don't really apply. The correct answer is therefore A.
When ATP is broken down to ADP we get a release of energy - B and C are therefore wrong. Energy is broken in more ways as only ADP - D is also wrong. Only A stays as the correct answer.
