Ques: Answer the following question given this paragraph: As a solid is heated, its particles vibrate more rapidly as the solid absorbs kinetic energy. Eventually, the organization of the particles within the solid structure begins to break down and the solid starts to melt. The melting point is the temperature at which a solid changes into a liquid. At its melting point, the disruptive vibrations of the particles of the solid overcome the attractive forces operating within the solid. As with boiling points, the melting point of a solid is dependent on the strength of those attractive forces. Sodium chloride (NaCl) is an ionic compound that consists of a multitude of strong ionic bonds. Sodium chloride melts at 801C. Ice (solid H 2 O) is a molecular compound whose molecules are held together by hydrogen bonds. Though hydrogen bonds are the strongest of the intermolecular forces, the strength of hydrogen bonds is much less than that of ionic bonds. The melting point of ice is 0C. Q: Which bonds are the strongest of the intermolecular forces? Choices: - complex - carbon - calcium - hydrogen A:
Ans: hydrogen

Answer the following question given this paragraph: There are other nerves in your body that are not found in the brain or spinal cord. The peripheral nervous system (PNS) ( Figure below ) contains all the nerves in the body that are found outside of the central nervous system. They include nerves of the hands, arms, feet, legs, and trunk. They also include nerves of the scalp, neck, and face. Nerves that send and receive messages to the internal organs are also part of the peripheral nervous system. Q: Nerves of the hands, arms, feet, legs, and trunk are part of what system? Choices: - urinary system - circulatory system - cardiovascular system - peripheral nervous system A:
(A).
peripheral nervous system
Ques:Answer the following question given this paragraph: Like other female vertebrates, all female mammals have ovaries. These are the organs that produce eggs (see Figure below ). Therian mammals also have two additional female reproductive structures that are not found in other vertebrates. They are the uterus and vagina. Q: The organs of female mammals that that produce eggs are called what? Choices: - testes - Uterus - fallopian tubes - ovaries A:

Ans:ovaries
