Which of the following statements is FALSE?
A. An organelle is a specialized structure in a cell, such as a ribosome.
B. An organ is made up of similar tissues that perform the same function.
C. Organ systems are two or more organs performing similar functions.
D. A tissue contains a single cell type that works to perform a specific function.
A tissue contains a variety of cell types that work in conjunction to perform similar functions.
The cells are similar in structure despite being located throughout the body. There are four types of tissues in the human body: connective, epithelial, muscle, and nervous system tissues.
Therefore, the Correct Answer is D.

Q #2: Which of the following statements best defines an organelle?
A. Layer of polysaccharides outside the plasma membrane of cells
B. Abnormal Infectious proteins
C. Specialized structures within a cell
D. Collection of tissues used to serve a specific function
Answer Explanation
Organelles are specialized structures within a cell that serve a specific function. For example, mitochondria supply energy to the cell by generating adenosine triphosphate. Ribosomes are the site for protein synthesis. The nucleus is in charge of all of the activities of the cell.

Q #5: Which of the following statements concerning the states of matter is NOT true?
A. Plasmas are high-temperature collections of ions and free electrons.
B. Solids are the least compressible due to the more rigid positions of the particles.
C. Gases have no definite volume and expand to fill their containers
D. Liquids have no definite shape and no definite volume.
Answer Explanation
Liquids have no definite shape, but they do have a definite volume. While the particles of liquids move more freely than those in solids, they do maintain a definite volume.

Q #6: Which of the following is exchanged between two or more atoms that undergo ionic bonding?
A. Neutrons
B. Transitory electrons
C. Valence electrons
D. Electrical charges
Answer Explanation
An ionic bond forms when one atom donates an electron from its outer shell, called a valence electron, to another atom to form two oppositely charged atoms.

Q #7: Which of the following conclusions is supported by the data from this survey?
A. Dally screen usage in the United States decreases with age
B. Daily screen usage in the United States, increases with age.
C. In the United States, most people use screens more than 3 but less than13 hours a day
D. In the United States, people over 75 generally don't use screens.
Answer Explanation
The percentage of respondents that indicated average screen usage between 4-12 hours per day is (628 +650+389) ÷ 2, 307 ≈ 0.723 or 72.3% This is indeed a significant majority of the responses and would be a reasonable conclusion. The highest screen usage is in the middle two groups with both the younger and older groups indicating less screen usage, so the daily usage neither increases nor decreases with age. While the oldest group shows the least usage per day, the survey data indicates that some of the Individuals over 75 do indeed use screens.

Q #8: A chemistry experiment is performed to determine the effect of a nonvolatile solute on the boiling point of water. Three trials are performed in which 10 mg, 20 mg, and 30 mg of salt are added to 500 mL of distilled water. Each solution is heated on a hot plate, and the elevated boiling points are recorded. Determine the dependent and independent variables in this question.
A. The independent variable is the amount of salt, and the dependent variable is the temperature at which the water boils.
B. The independent variable is the amount of water, and the dependent variable is the temperature at which the water boils.
C. The independent variable is the temperature at which the water boils, and the dependent variable is the amount of salt.
D. The Independent variable is the amount of salt, and the dependent variable is the amount of water.
Answer Explanation
In a scientific experiment, the dependent variable is the condition that is being tested and measured. The independent variable is the condition that is being changed or controlled. In this example, the amount of salt is varied, and the boiling point of water is measured. Therefore, the independent variable is the amount of salt, and the dependent variable is the temperature at which the water bolls.

Q #9: Which of the following answers shows CH4 +2O2=CO2 +H2O as balanced?
A. CH4 + 2O2 = 2CO2 + 2H2O
B. 2CH4 + 4O2 = 2CO2 + H2O
C. 2CH4 + O2 = 2CO2 + H2O
D. CH4 + 2O2 = CO2 + 2H2O
Answer Explanation
For the formula CH4 + 2O2 = CO2 + H2O to be balanced there must be an equal number of molecules on both the reactant and product sides. In this case, for the formula to be balanced, a coefficient of a 2 needs to be placed in front of the O2 and the H2O molecules. This would make both the reactant and product sides have one carbon, four hydrogens, and four oxygens

Q #10: In general, where in the periodic table of elements are the elements with the largest atomic radii located?
A. Upper-right corner
B. Upper-left corner
C. Bottom-left corner
D. Bottom-right comer
Answer Explanation
In general, atomic radius increases moving down a group due to the increasing number of electron shells. In general, atomic radius decreases moving from left to right across a period due to the increasing number of protons in the energy level. Therefore, atoms of elements in the bottom-left corner of the periodic table tend to have the largest atomic radii.
