Answer the following question given this paragraph: Significant figures are all of the digits that can be known with certainty in a measurement plus an estimated last digit. Significant figures provide a system to keep track of the limits of the original measurement. To record a measurement, you must write down all the digits actually measured, including measurements of zero, and you must not write down any digit not measured. The only real difficulty with this system is that zeros are sometimes used as measured digits, while other times they are used to locate the decimal point. Q: What are all of the digits that can be known with certainty in a measurement plus an estimatied last digit called? Choices: - determined figures - important figures - miniature figures - significant figures A:
significant figures

Answer the following question given this paragraph: Magnetism produced by electricity is called electromagnetism . Today, electromagnetism is used in many electric devices. However, until electromagnetism was discovered, scientists thought that electricity and magnetism were unrelated. A Danish scientist named Hans Christian Oersted (pictured in the Figure below ) changed all that. He made the important discovery that electric current creates a magnetic field. But like many other important discoveries in science, Oersted's discovery was just a lucky accident. Q: What magnetism is produced by electricity? Choices: - excitation - diffusion - Charges - electromagnetism A:
(Answer)
electromagnetism
Ques: Answer the following question given this paragraph: Fungi are eukaryotes in the Fungus Kingdom. Fungi include molds, which are multicellular, and yeasts, which are single-celled. Q: Molds and yeasts are organisms in what kingdom? Choices: - tissues - insects - aquatic - fungus A:
Ans: fungus

Answer the following question given this paragraph: Color is probably the easiest property to observe. Unfortunately, you can rarely identify a mineral only by its color. Sometimes, different minerals are the same color. For example, you might find a mineral that is a golden color and think it is gold. But it might actually be pyrite, or "fool's gold," which is made of iron and sulfide. It contains no gold atoms. Q: Although it is the easiest to observe, what property is not ideal as a sole way to identify minerals? Choices: - temperature - density - composition - color A:
(A).
color
Ques:Answer the following question given this paragraph: Ionic bonding. Ionic bonds result from electrostatic attractions between positively and negatively charged side chains of amino acids. For example, the mutual attraction between an aspartic acid carboxylate ion and a lysine ammonium ion helps to maintain a particular folded area of a protein (part (a) of http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch18_s04_s01_f05). Saylor URL: http://www. saylor. org/books. Q: Ionic bonds are what kind of attraction between ions? Choices: - kinetic - magnetic - nuclear - electrostatic A:

Ans:electrostatic
Question: Answer the following question given this paragraph: This type of joint is found between the articular processes of adjacent vertebrae, at the acromioclavicular joint, or at the intercarpal joints of the hand and intertarsal joints of the foot. Ball-and-socket joints, in which the rounded head of a bone fits into a large depression or socket, are found at the shoulder and hip joints. Both plane and ball-and-sockets joints are classified functionally as multiaxial joints. However, ball-and-socket joints allow for large movements, while the motions between bones at a plane joint are small. Q: The shoulder and hip are examples of what type of joints? Choices: - lever - pivot - hinge - ball and socket A:
Answer:
ball and socket
