Answer: d. all of the above

Fossil fuels such as coal, oil and gas are beneficial sources of energy used by the human society. Fossil fuels are non- renewable resources, which are produced after millions of years of geological and biological activity taking place inside the earth crust. Human society is mainly dependent upon the fossil fuels to maintain it's energy needs.

There are some negative consequences associated with fossil fuels:  

Environmental consequences: Fossil fuels are used for generation of energy in the power plants and by the automobiles. These sources releases partially and completely combusted products which includes the poisonous gases causing air and water pollution.

Economic consequences: Fossil fuel use is related with economic crisis because fossil fuels are non- renewable resources, which cannot be replenished once used. They are expensive and many commercial energy generation processes are dependent on them such as electricity, transportation and others.  

Development hindrances: Large dependence on fossil fuels creating an hindrance on development process. As, there are very few findings which are resulted which could replace the fossil fuels, these finding can be beneficial for the environmental and economic point of view.

Phosphorus (P) is the element with the atomic number 15. Which of the
viva [34]

Explanation:

   Isotopes:

                          ₁₅³¹P   and     ₁₅³²P

     Given parameters:

       ₁₅³¹P                                                   ₁₅³²P          

   Mass number = 31                                    32

   Atomic number = 15                                 15

The two atoms are isotopes. Now let us derive numbers of their subatomic particles

                       ₁₅³¹P                                             ₁₅³²P  

Protons              15                                                 15

Electrons           15                                                  15

Neutrons         (31-15) = 16                               (32-15) = 17

Because they are isotopes, they differ in the number of neutrons alone.

Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences  in the number of their neutrons.

We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

Your body contains tens of thousands of different proteins, each with a specific structure and function. The unique three-dimens
valkas [14]

Answer:

Each protein with a specific structure and function

The unique three dimensional shape of proteins is based on several superimposed levels of structure

Explanation:

Proteins are essential nutrients for human and a vital source of fuel for building body tissues. They are made up of amino acids linked together by peptide bonds. These amino acids act as precursor to nucleic acids, hormones, immune, repair of tissues among others.

Proteins contain 20 amino acids which are the building block for proteins. These amino acids can be reformed to create millions of protein in human body in which each protein has specific structure and function.

The three dimensional arrangement of atoms in an amino acid chain is know as the protein structure. The precise shape formed determine the protein function.
