An atom is the smallest known unit and it is present in all the matter. The space occupied by atom is divided into two components: the nucleus and orbitals. The nucleus is the center of the atom, and orbitals surround the nucleus.
Location of protons-
Protons are positively charged particles within atoms. Each atom has at least one proton. The number of protons determine the identity of an atom.Protons reside in the nucleus of the atom.
Location of Electron-
Electrons travel around the nucleus in the orbital. Electrons are negatively charged particles. In a neutral atom, the number of electrons and protons are same. Though they are much smaller than protons but have the same strength charge.
Location of Neutrons-
Neutrons are located with protons in the nucleus. They have no charge and have the same mass as protons. Not all atoms have neutrons, and the number of neutrons is not usually the same as protons or electrons.
Part B-
I agree with Jane's statement as an aluminium atom has a dense central nucleus surrounded by negatively charged electrons, The protons and neutrons are closely packed in the center an 13 electrons are surrounding this center.
<span>For the answer to the question above, the mRNA stands for messenger RNA. The job of the messenger RNA is to copy the code from the DNA and go through a ribosome so a protein can be created.
rRNA stands or ribosomal RNA. It is essentially the ribosome and is comprised of the large and small subunit. The rRNA allows the mRNA to go through rRNA in order to create the amino acid chain.
tRNA stands for transfer RNA. tRNA brings amino acids to the coordinating codon on the mRNA and matches it to the correct codon.

Explanation:
The collaboration of human beings began in the past especially to offer security for offspring. Families living in communities had prolonged life for offspring due to collective security for the benefit of the whole community. Even when some members of community went to hunt or gather food, they are assured to the security of their offspring living in the community. It is believed it is such acts of collaboration that evolved into the current social fabric of society.
