Answer: double helix
Explanation: The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
Answer:
Work is the transfer of energy , Energy is the capacity for <em>doing</em> work , and Power is work being done in a unit of time.
There are 2 types of energy
Kinetic Energy : Energy of Motion
Potential Energy : Stored Energy
When calculating work energy and power you use WORK = W=Fd
Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.
