Q: What have approximately the same mass as protons but no charge? Read this paragraph and choose the correct option from the provided answers: Neutrons have approximately the same mass as protons but no charge. They are electrically neutral. The mass of a proton or a neutron is about 1836 times greater than the mass of an electron. Protons and neutrons constitute by far the bulk of the mass of atoms. The discovery of the electron and the proton was crucial to the development of the modern model of the atom and provides an excellent case study in the application of the scientific method. In fact, the elucidation of the atom's structure is one of the greatest detective stories in the history of science. Choices: - atoms - reactions - electrons - neutrons A:
(Answer)
neutrons

Q: Ribosomes are produced in the nucleolus, and then transported to the what? Read this paragraph and choose the correct option from the provided answers: Ribosomes are produced in the nucleolus, and then transported to the cytoplasm. Ribosomes are made of ribosomal proteins, called ribonucleoproteins , and ribosomal RNA (rRNA). Each ribosome has two parts, a large and a small subunit, as shown in Figure below . The subunits are attached to each other. During translation, the smaller subunit binds to the mRNA, while the larger subunit binds to the tRNA with attached amino acids. When a ribosome finishes reading an mRNA molecule, the two ribosomal subunits disassociate. Choices: - cerebellum - nucleus - cytoskeleton - cytoplasm A:
(Answer)
cytoplasm
