Problem:OPTIONS:
- radius
- electron shell
- epidermis
- nucleus

Answer the following question given this paragraph: Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. The Figure below is a common way to represent the structure of an atom. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. Q: Where are protons and neutrons located? A:
****
A: nucleus

Answer the following question given this paragraph: DNA is located in the nucleus. Proteins are made on ribosomes in the cytoplasm. Remember that information in a gene is converted into mRNA , which carries the information to the ribosome. In the nucleus, mRNA is created by using the DNA in a gene as a template. A template is a model provided for others to copy. Q: What are made on ribosomes in the cytoplasm? A:
OPTIONS:
- lipids
- cells
- enzymes
- proteins

Answer: proteins
