ATI TEAS TEST PRACTICE The price of a 20" television changed from $450 to $400. Find the percentage change in price. A. -10% Correct answer: -11% Change in price: 450 - 400 = 50 To determine the percentage change, divide the change in price by the initial price: B. -11% 50 = 0.1111 450 C. -13% Multiply by 100 to determine the percentage: 0.1111 × 100 = 11.11% D. -15% Because the price decreased, the change in price is negative: -11.11%, or about -11% Which of the following is not a type of natural lipid? A. Supersaturated B. Polyunsaturated C. Saturated D. Unsaturated Correct answer: Supersaturated There are three types of natural lipids: unsaturated, polyunsaturated, and saturated. Supersaturation is a not a naturally occurring lipid. Unsaturated and polyunsaturated lipids have one or more double bonds between carbon atoms of fatty acid chains; saturated lipids share no such double bonds. A common example of supersaturation is rock candy, which is created from a supersaturated sugar solution. Correct answer: Daughter cells are different than parent cells Which of the following is not true of mitosis? A. Daughter cells are different than parent cells B. Daughter cells are identical to parent cells C. It produces daughter cells D. It occurs only in eukaryotic cells What is the role of the Golgi apparatus in the cell? A. To uptake food through the cell membrane B. To produce cellular respiration C. To provide intracellular digestion Mitosis is a cell cycle during which a parent cell produces an identical daughter cell. It has four main phases: prophase, metaphase, anaphase, and telophase. Since the parent and daughter cells are identical, both diploids and haploids can undergo mitosis. Mitosis is a four-stage process that creates two identical cells from one original cell. Prophase is the first and longest stage of mitosis. In this stage, the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. Metaphase is the second stage of mitosis. In this stage, the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere. Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart. Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. Correct answer: To provide transportation of materials throughout the cell The Golgi apparatus is responsible for the transportation of materials throughout the cell. The Golgi apparatus, also known as the Golgi complex, Golgi body, or simply the Golgi, is an organelle found in most eukaryotic cells. Intracellular digestion occurs within lysosomes. Uptaking food is 1/8 the job of vacuoles. Cellular respiration is the function of mitochondria. D. To provide transportation of materials throughout the cell When hydrocarbon is heated, its products are carbon dioxide and water. This is an example of which of the following? Correct answer: Combustion A. Decomposition B. Combustion C. Single replacement D. Synthesis When is a double covalent bond formed? A. When two electron pairs are shared between two atoms B. When two neutrons bond within an atom C. When two electrons bond within an atom D. When two neutron pairs are shared between two atoms An example of combustion is when hydrocarbon is heated and its products are carbon dioxide and water. Combustion is an exothermic chemical reaction that occurs when heat acts on oxygen or a fuel compound. Synthesis is a reaction that causes two elements to join to form one product. Decomposition occurs when a compound is broken down into its component parts. Single replacement occurs when an active metal reacts with an ionic compound that contains a less active metal to form a new compound. Correct answer: When two electron pairs are shared between two atoms A double covalent bond is formed when two electron pairs are shared between two atoms. A general covalent bond is formed when two atoms share their electrons. Covalent bonds are the strongest type of chemical bond. When two electrons bond within an atom is incorrect because two atoms need to share two electron pairs in order for a double covalent bond to form. When two neutron pairs are shared and when two neutrons bond are incorrect because covalent bonds are formed when electrons are shared. Which suffix should be added to a word function to indicate resembling? Correct answer: -oid A. -ess The suffix -oid is added to a word function to indicate resembling. For example, tabloid means resembling a newspaper, and spheroid means resembling a sphere. B. -oid The suffix -ive is added to a word function to indicate causing or making. The suffix -ess is added to a word function to indicate female. The suffix -fy is added to a word function to indicate make. C. -fy D. -ive Atoms are made up of all except which of the following? A. Electrons B. Isotopes C. Protons Correct answer: Isotopes Isotopes are atoms that have an equal number of protons but a different number of neutrons. Thus, atoms are made up of protons, neutrons, and electrons. The diagram further illustrates the composition of the atom. D. Neutrons To which body system does cartilage belong? Correct answer: Skeletal system A. Neuromuscular system 2/8 B. Respiratory system C. Integumentary system D. Skeletal system The skeletal system has three main functions: movement, protection, and metabolism. The skeletal system is composed of bone, which is an organ that is constantly being reorganized. Bones synthesize blood and immune cells, as well as store calcium, phosphate, and lipids. Bone is a dynamic tissue that is made and broken down according to need. It also functions to provide structural, protective, and metabolic needs. In which of the following phases of matter do the molecules exert a strong attraction to one another as they move slowly relative to one another? Correct answer: Solid A.

In this stage, the chromosomes become visible and the centrioles separate and move to opposite poles of the cell. Metaphase is the second stage of mitosis. In this stage, the Mitosis is a type of asexual reproduction. This cell division process chromosomes line up across the center of the cell and become occurs in how many stages? connected to the spindle fiber at their centromere. Anaphase is the third stage of mitosis. In this stage, the sister chromatids separate into individual chromosomes and are pulled apart. Telophase is the fourth and last stage of mitosis. During this stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod-like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear. 1If one atom of element X with a charge of 3- reacts with two atoms of element Y with a charge of 1+ each, what is the charge of the There is a total of 2+ and 3- charges.

Epistasis It is known that the gene that codes for male pattern baldness Epistasis is a phenomenon that consists of the effect of one gene depends on the gene for red hair. This type of interaction between being dependent on the presence of one or more 'modifier genes' alleles is known as which of the following? (genetic background). Similarly, epistatic mutations have different effects in combination than individually. 79,680 cubic inches First, find out how many hours are in two days. 1 day = 24 hours 1 day x 2 = 24 hours x 2 = 48 hours In 3 hours, 20 cubic inches is lost. Set up a proportion to find out how much water is lost in 48 hours. A tank loses 20 cubic inches of water after 3 hours through 3 hours/20 cubic inches = 48 hours/x number of cubic inches leakage. If the tank has 80,000 cubic inches of water, how much will remain in the tank after a total of two days? 3/20 = 48/x 3x = 960 x = 320 cubic inches Because the question asks for the remaining quantity, rather than the amount lost, subtract this amount from the original amount in the tank. 80,000 - 320 = 79,680 cubic inches 7/16 The operation is 1 - (3/4 × 3/4). Find the result of the following operation: First multiply 3/4 by 3/4. Multiply 3/4 by itself then subtract the result from 1. 3/4 × 3/4 = 9/16 6/8 Solve the expression by converting 1 into a fraction. 1 - 9/16 16/16 - 9/16 = 7/16 Fast food For his science fair project, Clay ate fast food for breakfast, lunch, and dinner for two solid weeks and changed no other lifestyle habit during that time period. Clay recorded his weight, blood pressure, and cholesterol level before and after the experiment, which is reflected in the provided table. An independent variable is the object that is being measured as a possible cause. In this experiment, the independent variable is fast food, as it is being consumed in order to measure the possible cause (increased weight, blood pressure, and cholesterol). Weight, blood pressure, and cholesterol is incorrect because they are the experiment's dependent variables. Individual and lifestyle habits are incorrect because they are the experiment's controlled variables. What is the independent variable(s) for this experiment? 21/20 To convert 1.05 into a fraction, first change it into an improper fraction. How would 1.05 be displayed as a fraction? 1 5/100 = (100 × 1 + 5)/100 = 105/100 Reduce the fraction by dividing both numerator and denominator by 5. 105/100 ÷ 5/5 = 21/20 him I asked him to mow the lawn today while I was at work.
