1. Another word for UBIQUITOUS is?

• A. Widespread
• B. Last demand
• C. Uncertainty
• D. Finally reckoned

Correct answer: A

Rationale: The word "ubiquitous" means present, appearing, or found everywhere. Another word that closely relates to this meaning is "widespread," which also refers to something that is prevalent or found in many places. The other choices, such as "last demand," "uncertainty," and "finally reckoned," do not accurately represent the synonym for "ubiquitous."

2. What kind of bond connects sugar and phosphate in DNA?

• A. hydrogen
• B. ionic
• C. covalent
• D. overt

Correct answer: C

Rationale: Sugar and phosphate are indeed connected by covalent bonds in DNA. Covalent bonds involve the sharing of electrons between atoms, which is essential for forming the backbone of the DNA molecule. Hydrogen bonds (Choice A) are important in holding the nitrogenous bases together in the DNA double helix but do not connect sugar and phosphate. Ionic bonds (Choice B) involve the transfer of electrons between atoms and are not the primary bond connecting sugar and phosphate in DNA. 'Overt' (Choice D) is not a type of chemical bond and is an incorrect distractor.

3. At what temperature does water boil in °F?

• A. 210°F
• B. 212°F
• C. 215°F
• D. 220°F

Correct answer: B

Rationale: Water boils at 212°F under standard atmospheric pressure. This is the point at which water changes from a liquid to a gas phase. Choice A (210°F) is incorrect as it is below the boiling point of water. Choice C (215°F) and Choice D (220°F) are also incorrect as they are above the boiling point of water.

4. What is the net force acting on the car?

• A. 450 N
• B. 700 N
• C. 1,500 N
• D. 6,300 N

Correct answer: C

Rationale: To determine the net force acting on an object, we need to consider the sum of the forces acting in the same direction and subtract the forces acting in the opposite direction. In this scenario, there is a force of 4,200 N to the right and a force of 2,700 N to the left. By subtracting the leftward force from the rightward force (4,200 N - 2,700 N), we find that the net force acting on the car is 1,500 N to the right. Therefore, choice C, 1,500 N, is the correct answer. Choice A, 450 N, is too small as it does not account for the total forces involved. Choice B, 700 N, is also incorrect as it is not the result of the correct mathematical operation on the given forces. Choice D, 6,300 N, is too large and does not align with the calculation based on the forces provided.

5. What is the best description for the term doleful?

• A. Unwell
• B. Deprived
• C. Conceited
• D. Downcast

Correct answer: D

Rationale: The term 'doleful' is best described as feeling or expressing sorrow or sadness. 'Downcast' aligns with this meaning as it refers to having a dejected or low spirit, which matches the nature of doleful. Options A, B, and C do not directly relate to the sense of sadness or sorrow that doleful conveys. 'Unwell' means in poor health, 'deprived' means lacking something essential, and 'conceited' means having an excessively favorable opinion of oneself, none of which capture the essence of doleful.
