Answer the following question given this paragraph: Metals have a wide range of melting points, but most are quite high. Only one metal (mercury) melts below room temperature. Others (such as gallium) are solid at room temperature but would melt at body temperature, so they can be melted simply by holding them in your hand. On the other end of the spectrum, tungsten has a melting point of 3422C. Figure below shows the melting points of various elements in their most common pure form. Q: Name the one metal that melts below room temperature? Choices: - aluminum - gold - bronze - mercury A:
mercury

Answer the following question given this paragraph: Since then, the distinction between organic and inorganic compounds and reactions has blurred. Currently, the field of organic chemistry studies the structure and reactivity of nearly all carbon-containing compounds. Over twenty million organic compounds are known, ranging from very simple molecules to complex proteins. Q: The field of organic chemistry studies the structure and reactivity of compounds containing what element? Choices: - nitrogen - hydrogen - oxygen - carbon A:
(Answer)
carbon
Ques: Answer the following question given this paragraph: Speed is the distance traveled divided by the time it took to travel that distance. Velocity is the instantaneous speed and direction. Average velocity is the displacement divided by the time. Q: What term is used to describe the distance traveled divided by the time it took to travel that distance? Choices: - movement - motion - velocity - speed A:
Ans: speed

Answer the following question given this paragraph: Matter is all the "stuff" that exists in the universe. Everything you can see and touch is made of matter, including you! The only things that aren't matter are forms of energy, such as light and sound. In science, matter is defined as anything that has mass and volume. Mass and volume measure different aspects of matter. Q: In science, anything that has mass and volume is considered what? Choices: - renewable - visible - an element - matter A:
(A).
matter
Ques:Answer the following question given this paragraph: Cells are found in all different types of environments, and these environments are constantly changing. For example, one-celled organisms, like bacteria, can be found on your skin, in the ground, or in all different types of water. Therefore, cells need a way to protect themselves. This job is done by the cell membrane, which is also known as the plasma membrane. Q: Name a one-celled organism that can be found on your skin, in the ground, or in all different types of water. Choices: - virus - fungus - pathogens - bacteria A:

Ans:bacteria
Ques:Answer the following question given this paragraph: Different seafloor magnetic stripes equal different ages. By using geologic dating techniques, scientists could figure out what these ages are. They found that the youngest rocks on the seafloor were at the mid-ocean ridges. The rocks get older with distance from the ridge crest. Scientists were surprised to find that the oldest seafloor is less than 180 million years old. This may seem old, but the oldest continental crust is around 4 billion years old. Q: Geologists found that the youngest rocks on the seafloor were where? Choices: - early - ocean ridges - late - ocean ridges - seabed floor - mid - ocean ridges A:

Ans:
mid - ocean ridges
