to-one correspondence with the set o f points on a line. That is, each real number corresponds to exactly one point on a line, and each point on a line corresponds to exactly one real number, called the _____ of the point - ✔✔✔ ANSWER > coordinate A natural number is _____ if it is greater th an 1 and not prime. - ✔✔✔ ANSWER > composite A negative exponent indicates a reciprocal. For example, - ✔✔✔ ANSWER > 2 ( -
3rd power) = (3rd power) = A simple food chain might look like this: - ✔✔✔ ANSWER > sun → grass → grasshopper → toad → snake → hawk → bacteria of decay Amplitude. - ✔✔✔ ANSWER > A measure of the distance between a wave's crest and trough and an area, A, given by - ✔✔✔ ANSWER > A = πr² Animal and plant cells contain smaller structures, called _____, which are specialized to fulf ill specific functions within the cell. Mitochondria, for example, break down glucose to provide energy to the cell. Bacterial cells lack most of these organelles. - ✔✔✔ ANSWER > organelles Archaea. - ✔✔✔ ANSWER > Archaea are microorganisms similar to bact eria in form but genetically so vastly different from everything else on the planet that they deserve their own unique branch on the tree of life. Archaea are often found in extreme environments including acidic conditions, boiling hot springs, deep ocean vents, or polar ice. Associative property. - ✔✔✔ ANSWER > When adding three or more numbers, the sum is the same regardless of the way in which the numbers are grouped. 2 + (3 + 5) = (2 + 3) + 5 At the present time, scientists believe that the most fundam ental particle of matter is the _____. - ✔✔✔ ANSWER > quark Atoms are neither gained nor lost during a chemical change. This is the _____ ______ _____ _____ _____ ; matter can neither be created nor destroyed in a chemical reaction. In a chemical change, h owever, a new substance is formed, and there may be accompanying clues that a chemical reaction has taken place, such as light, heat, color change, gas production, odor, or sound. - ✔✔✔ ANSWER > Law of Conservation of Matter autotrophic organisms) - ✔✔✔ ANSWER > are capable of harnessing energy from sunlight and using it to produce glucose, the main source of energy for the organism. Chemical energy. - ✔✔✔ ANSWER > Energy stored in bonds of atoms and molecules is described as chemical energy. Gasoline and coal contain stored chemical energy. Chlorophyll, which is contained within a cell organelle called the ______, captures the light from the Sun; - ✔✔✔ ANSWER > chloroplast Commensalism. - ✔✔✔ ANSWER > In a commensal relationsh ip, members of different species live together, and one member benefits without seriously affecting the other party. As a rule, the animal that benefits is usually the physically smaller of the two. The commensal organism may depend on its host for food, s helter, support, or transportation. The animal that benefits is known as the commensal, or symbiont, while the nonbenefitting species is known as the host. For example, some flatworms live attached to the gills of the horseshoe crab, obtaining bits of food from the horseshoe crab's meals; the horseshoe crab is apparently unaffected. Commutative property. - ✔✔✔ ANSWER > When adding two numbers, the sum is the same regardless of the order in which the numbers are added. 2 + 3 = 3 + 2 Complete Metamorphosis - ✔✔✔ ANSWER > See the last four Compound machines - ✔✔✔ ANSWER > are two or more simple machines working together. A wheelbarrow is an example of a complex machine that uses a lever and a wheel and axle. Machines of all types make work easier by changing the size or direction of an applied force.
