Answer: DNA is a polymer of nucleotides, which consist of a sugar, a phosphate group, and a nitrogenous base
Explanation:
Every molecule in the human body are formed by the chains of particular substances. These components are arranged orderly as linked chains to give the structure called DNA.
The components include nucleotides—this is also considered the chemical substance in the human body which helps in the formation.
In this formation of chains, nitrogenous bases will also be linked to form a polymer of DNA.
C is my guess could be wrong just guessing
Answer:
The correct answer is c a power plant burning coal and producing electricity.
Explanation:
According to the first law of thermodynamics it can be stated that energy can neither be created nor destroyed.Energy can only be transformed.The total amount of energy of universe always remains constant.
A powerplant burning coal and producing electricity best suits the first law of thermodynamics because here the heat energy is being converted into electric energy and no energy is lost during the transformation of energy.
Answer:
The correct answer will be option A-the accepted model of the atom was changed.
Explanation:
J.J Thomson discovered the electrons by cathode ray tube experiment in 1897 and realized that the accepted model of atom as proposed by the Dalton has problems as he stated that "atom is indivisible".
The discovery of sub-atomic particles-electrons in his experiments showed that the atom can be divided into sub-atomic particles and he proposed the pudding model of the atom which changed the accepted model of atom at that time.
Thus, option A-the accepted model of the atom was changed is the correct answer.
