Answer the following question given this paragraph: From left to right across the periodic table, each element has one more proton than the element to its left. Because atoms are always electrically neutral, for each added proton, one electron is also added. Electrons are added first to the lowest energy level possible until that level is full. Only then are electrons added to the next higher energy level. Q: Because atoms are always electrically neutral, for each added proton, one of what is also added? Choices: - ion - quark - neutron - electron A:
(Answer)
electron
Ques: Answer the following question given this paragraph: The melting point of a substance is the temperature that separates a solid and a liquid. The boiling point of a substance is the temperature that separates a liquid and a gas. What accounts for this variability? Why do some substances become liquids at very low temperatures, while others require very high temperatures before they become liquids? It all depends on the strength of the intermolecular interactions between the particles of substances. (Although ionic compounds are not composed of discrete molecules, we will still use the term intermolecular to include interactions between the ions in such compounds. ) Substances that experience strong intermolecular interactions require higher temperatures to become liquids and, finally, gases. Substances that experience weak intermolecular interactions do not need much energy (as measured by Saylor URL: http://www. saylor. org/books. Q: Melting points are temperatures that are high enough to separate liquids from which substances? Choices: - gases - seeds - oils - solids A:
Ans: solids

Answer the following question given this paragraph: Fragmentation occurs when a piece breaks off from a parent organism. Then the piece develops into a new organism. Sea stars, like the one in Figure below , can reproduce this way. In fact, a new sea star can form from a single "arm. ". Q: What's the term for a piece of an organism breaking off and forming a new organism? Choices: - depletion - improvization - extinction - fragmentation A:
fragmentation
