_______________ make(s) up the nucleus of an atom.
- a. Protons and electrons
- b. Protons and neutrons
- c. DNA and RNA
- d. Neutrons and electrons
- e. DNA only

Introduction: Atom is the smallest structural unit of any matter. The nucleus is the centermost part of the atom. The atom consists of proton, electron, and neutron. Multiple numbers of atoms combine together and form the molecules.
Answer to Problem 1TY
Correct answer: The “protons and neutrons” forms the nucleus of an atom. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
The nucleus of the atom is formed by the “neutrons and protons”. These two particles provide the mass to the atom and both the particles are heavier than the electron. The charge possessed by the proton is positive in nature. However, in the case of neutrons, the charge is not present. Both the particles are present in the nucleus of an atom and the electrons circulate around them in their orbitals.
Option b. is given as “Protons and neutrons”.
The “protons and neutrons” are found in the nucleus of an atom. Hence, the correct answer is option b.
Reason for incorrect answer:
Option a. is given as “Protons and electrons”.
The electrons are found in the orbitals present outside the nucleus. The protons and neutrons are present inside the nucleus. Hence, option a. is incorrect.
Option c. is given as, “DNA and RNA”.
DNA and RNA are made up of a number of atoms and they are found in the nucleus of the cell, not in the nucleus of the atom. So, the possibility of the presence of DNA and RNA inside the atom nucleus is negligible. Hence, option c. is incorrect.
Option d. is given as “Neutrons and electrons”.
Electrons are present on the orbitals and they surround the nucleus of an atom in their respective energy levels. The protons and neutrons are present inside the nucleus. Hence, option d. is incorrect.
Option e. is given as, “DNA only”.
The DNA stands for “deoxyribonucleic acid”. Presence of DNA molecule is found in case of the cellular nucleus, not in the atom nucleus. Hence, option e. is incorrect.
Hence, the options a., c., d., and e. are incorrect.
Inside the nucleus of an atom, the “protons and neutrons” are found.

- Plekhg5 functions in bottle cell formation, and Shroom3 functions in neural plate closure, yet the phenotype of injecting mRNA of each into the animal pole of a fertilized egg is very similar. What is the phenotype, and why is the phenotype so similar? Is the phenotype going to be that there is a disruption of the formation of the neural tube for both of these because bottle cell formation is necessary for the neural plate to fold in forming the neural tube and Shroom3 is further needed to close the neural plate? So since both Plekhg5 and Shroom3 are used in forming the neural tube, injecting the mRNA will just lead to neural tube deformity?arrow_forwardWhat are some medical issues or health trends that may have a direct link to the idea of keeping fat out of diets?arrow_forwardwhat did charles darwin do in sciencearrow_forward

Your instructor will give you 2 amino acids during the activity session (video 2-7. A. First color all the polar and non-polar covalent bonds in the R groups of your 2 amino acids using the same colors as in #7. Do not color the bonds in the backbone of each amino acid. B. Next, color where all the hydrogen bonds, hydrophobic interactions and ionic bonds could occur in the R group of each amino acid. Use the same colors as in #7. Do not color the bonds in the backbone of each amino acid. C. Position the two amino acids on the page below in an orientation where the two R groups could bond together.
