Natural selection occur to give the best survival chance to the organisms. Hence, they bring about biological evolution through future generations thereby increasing the variety of living things. This survival reflects on their ability to produce more offspring. The offspring must continue to survive by competing with the resources found in nature.
Answer:
c. Protons, electrons
Explanation:
The number of these electrons in a neutral atom is equivalent to the number of protons.
Since protons have positive charge, they balanace the negative charge of electrons. Electrons have same level of charge per particle as a proton.
Neutrons posses no charge, so in a "neutral atom" the number of proton is equal to that of electrons, othermeans it will not be neutral.
When a electron is removed by natural or artificaial means , an ion results which is an electrically charged particle. It also happens some atoms take additonal electrons once they were previously neutral. They can also lose electrons and become positively charged,
"Proton" <span>determines the identity of an element!
So, option A is your answer!
