1. hich word is most closely associated with the adjective "meticulous"?

• A. careless
• B. precise
• C. indifferent
• D. enthusiastic

Correct answer: B

Rationale: "Meticulous" implies carefulness and attention to detail, making "precise" its closest synonym.

2. Neon (Ne). Both He and Ne belong to Group 18 (Noble Gases) due to their complete and stable outer electron shells.

• A. Electromagnetism
• B. Gravity
• C. Strong nuclear force
• D. Weak nuclear force

Correct answer: C

Rationale: Strong nuclear force. This incredibly powerful force overcomes the repulsive electrostatic force between protons and binds the nucleus together.

3. Which type of muscle is characterized by involuntary contractions, is striated, and is primarily found in the heart?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Elastic muscle

Correct answer: C

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by involuntary contractions, meaning it contracts without conscious control. It is striated, which refers to the striped appearance of muscle fibers under a microscope. Cardiac muscle is primarily found in the heart, where it plays a crucial role in pumping blood throughout the body. Skeletal muscle (option A) is also striated but is under voluntary control. Smooth muscle (option B) is non-striated and found in organs like the intestines. Elastic muscle (option D) is not a recognized type of muscle tissue.

4. Which word is spelled correctly?

• A. Accomodate
• B. Acquiesce
• C. Percieve
• D. Dilema

Correct answer: B

Rationale: Option B is the correct spelling for "to submit or agree without protest."

5. What is the Aufbau principle?

• A. The principle that electrons fill orbitals in order of increasing energy.
• B. The principle that electrons cannot be in the same orbital with the same spin.
• C. The principle that the maximum number of electrons in an orbital is 2n^2, where n is the energy level of the orbital.
• D. The principle that the attractive force between an electron and the nucleus is inversely proportional to the distance between them.

Correct answer: A

Rationale: The Aufbau principle is a fundamental concept in atomic structure that determines the order in which electrons fill the available orbitals in an atom. It states that electrons occupy orbitals in order of increasing energy levels, starting with the lowest energy level and progressing to higher energy levels. This principle is based on the fact that electrons in lower energy levels are more stable and have a lower energy state than electrons in higher energy levels.

6. What is the building block of DNA?

• A. Amino acid
• B. Nucleotide
• C. Nucleotide
• D. Fatty acid

Correct answer: B

Rationale: Rationale: - Amino acids are the building blocks of proteins, not DNA. - Nucleotide is the correct building block of DNA. A nucleotide consists of a sugar (deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). - The option "C) Nucleotide" is a duplicate of the correct answer "B) Nucleotide." - Fatty acids are not the building blocks of DNA; they are a type of lipid molecule.
