Answer:
The correct answer would be - D. What causes cancer cells to grow uncontrollably?
Explanation:
A Biologist is a person that studies living organisms and the study of living organisms and their process called biology. Biology is a very vast field that involves many branches such as zoology, botany, biochemistry, immunology, biophysics, anatomy, ecology and many more.
So, given all are can be an example of the study biology wanted to do, however, the question most likely studied by a biologist would be What causes cancer cells to grow uncontrollably as it deals with an organism and their biological process.
Mass Number quantifies the number of protons and neutrons in the atom. Electrons are so small that they do not even matter in the calculation. Protons and Neutrons are approximately 1 A. Atomic Number refers to where the atom is on the periodic table, such as Hydrogen being Atomic Number 1, but also quantifies the number of protons. In your situation the atomic number is 32 meaning it is Germanium but also meaning it has 32 protons. When we add the number of protons and number of neutrons to find the mass number we do 32 (protons) + 31 (neutrons) to get a total mass number of 63. 63 is your answer.
