Answer
I think it might be B
Explanation
Answer: The mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.
Explanation:
Atomic number is defined as the number of protons or number of electrons that are present in an atom.
For a neutral atom:
Atomic number = Number of electrons = Number of proton
Atomic number= Number of protons = 8
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Given: Number of neutrons = 9
Thus mass number = Number of protons + Number of neutrons = 8 + 9 = 17.
Isotopes are elements which have same atomic number but different mass number.
Thus the mass number of an oxygen isotope that has nine neutrons is 17 and isotope is called as Oxygen-17.
Answer:
The electrons stripped from glucose in cellular respiration end up in compound water by the reduction of oxygen.
Explanation:
During electron transport chain electrons are donated by various reducing equivalents such as NADH,FADH2.The donated electrons then moves through various electron carriers .
During electron transport chain oxygen(O2) act as terminal electron acceptor which accept the electron from complex 4 and thereby get reduced to form water.(H2O).
