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.

Answer:
C. petals
Explanation:
A)fruits
B)sepals
C)petals
D)anthers
E)ovaries
<em>The part that will not be necessary in wind pollinated angiosperm is the petals .</em>
The petal is a part of flower that is usually colorful and primarily function by attaracting insect pollinators to the flower.
<u>Since wind pollinated angiosperms do not need to attract insect for pollination, they do not need the colorful petals. They rely on wind to carry their pollen from their anthers to their stigmas (pollination).</u>
Hence, the correct option is C.
