Answer:
A. The light waves squeeze together increasing wavelength
Explanation:
Answer:
So if you touch an electric circuit and the ground at the same time, you will become electricity's easiest path. Electricity will flow through you, and you could be seriously hurt or killed. You don't have to be touching the ground directly to conduct electricity.
Explanation:
Adaptation is the process by which become suited to their environment
The answer is option B. The number of protons
If two atoms are isotopes of the same element then the number of protons in those two atoms must be same but the number of neutrons must not be same. If number of neutrons of an atom vary but number of protons in them are same then it simply means that they both are isotopes of a particular element. As we know that every atom has a nucleus which has protons and neutrons and due to these protons and neutrons an atom has weight. Apart from that, an atom has electrons too but they are outside the nucleus. Electrons are extremely light in weight so they do not contribute towards weight but they have a great role in chemical reactions. During chemical reactions, it is electron which directly participates, while proton and neutrons do not take part or move during chemical reactions. Also, in a neutral atom number of protons is equal to number of electrons but when an atom becomes negatively or positively charged, it can gain or loose electrons so electrons have tendency to vary. That is why we cannot consider electrons to be always same for isotopes of an element. It is clear that for an isotope, the number of electrons and neutrons will vary but the number of protons will always be fixed.
