Answer the following question given this paragraph: Rutherford's atomic model became known as the nuclear model . In the nuclear atom, the protons and neutrons, which comprise nearly all of the mass of the atom, are located in the nucleus at the center of the atom. The electrons are distributed around the nucleus and occupy most of the volume of the atom. It is worth emphasizing just how small the nucleus is compared to the rest of the atom. If we could blow up an atom to be the size of a large professional football stadium, the nucleus would be about the size of a marble. Q: In an atom, what two major types of particles are located in the nucleus? A:

OPTIONS:
- electrons and neutrons
- molecules and neutrons
- ions and electrons
- protons and neutrons

Answer: protons and neutrons

Problem: OPTIONS:

Answer the following question given this paragraph: Two unique features of mollusks are the mantle and radula (see Figure above ). The mantle is a layer of tissue that lies between the shell and the body. It secretes calcium carbonate to form the shell. It forms a cavity, called the mantle cavity , between the mantle and the body. The mantle cavity pumps water for filter feeding. The radula is a feeding organ with teeth made of chitin. It is located in front of the mouth in the head region. Herbivorous mollusks use the radula to scrape food such as algae off rocks. Predatory mollusks use the radula to drill holes in the shells of their prey. Q: What are the two unique features of mollusks? A:
OPTIONS:
- antennae and pseudopod
- pseudopod and mantle
- radula and antennae
- mantle and radula
mantle and radula
