Answer:
true, they both have different types of DNA.
Answer: 45
Explanation:
Recall that mass number = number of protons + number of neutrons. Hence, the mass number of the atom
= 22 + 23
= 45
Furthermore, the atomic number is equal to the number of protons. Hence, since the number of protons is 22. the atom has an atomic number of 22
Thus, An atom that contains 22 protons,
23 neutrons, and 22 electrons would have a mass of approximately 45
B I hope it’s right I don’t really help a lot but yeah lol
Plants that have nigrogen fixing bacteria in their roots are called
legumes.
False. elements in the same period have the same number of shells while elements in the same group have the same number of valence electrons.
