1. The author's tone towards UBI can be described as

• A. Strongly supportive, advocating for its immediate implementation without reservations.
• B. Strongly critical, highlighting only the potential drawbacks and dismissing its benefits.
• C. Neutral and objective, presenting both sides of the argument without taking a stance.
• D. Cautiously optimistic, acknowledging both the potential and challenges while calling for further discussion.

Correct answer: D

Rationale: The passage acknowledges both positive and negative aspects of UBI, suggesting a cautious and balanced perspective, aligning with D.

2. What is the main function of the endoplasmic reticulum (ER) in the cell?

• A. To synthesize and transport proteins and lipids
• B. To package and transport proteins
• C. To break down macromolecules
• D. To store genetic material

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

3. Which muscle type is characterized by a combination of voluntary and involuntary control, is striated, and is responsible for pumping blood throughout the circulatory system?

• A. Skeletal muscle
• B. Smooth muscle
• C. Cardiac muscle
• D. Connective tissue

Correct answer: c

Rationale: The correct answer is C: Cardiac muscle. Cardiac muscle is characterized by a combination of voluntary and involuntary control, as the heart can beat involuntarily while also responding to signals from the autonomic nervous system. It is striated, meaning it has a striped appearance under a microscope due to the arrangement of contractile proteins. Cardiac muscle is responsible for pumping blood throughout the circulatory system, making it crucial for maintaining circulation and delivering oxygen and nutrients to tissues. Skeletal muscle (option A) is primarily under voluntary control and is responsible for movement, while smooth muscle (option B) is predominantly involuntarily controlled and found in organs like the intestines. Connective tissue (option D) provides support and structure but is not a muscle type responsible for pumping blood.

4. What is the term for the particles moving around within a substance?

• A. Ions
• B. Atoms
• C. Molecules
• D. Kinetic energy

Correct answer: C

Rationale: In most cases, the particles moving within a substance are individual molecules or atoms, depending on the state of matter.

5. Define the term "momentum" in physics.

• A. Force exerted on an object
• B. Speed of an object in motion
• C. Mass in motion
• D. Distance traveled per unit time

Correct answer: c

Rationale: Momentum is the product of an object's mass and velocity, describing its motion and resistance to changes in motion.

6. What is the process of copying DNA called?

• A. Transcription
• B. Translation
• C. Replication
• D. Mutation

Correct answer: C

Rationale: Rationale: A) Transcription is the process of creating an RNA copy of a segment of DNA. It involves the synthesis of mRNA from a DNA template. B) Translation is the process of synthesizing a protein from an mRNA template. It involves the conversion of the mRNA sequence into a sequence of amino acids. C) Replication is the process of copying DNA to produce an identical copy. During replication, the DNA double helix unwinds and each strand serves as a template for the synthesis of a new complementary strand, resulting in two identical DNA molecules. D) Mutation refers to a change in the DNA sequence that can result from errors during replication, exposure to mutagens, or other factors. While mutations can occur during replication, the process of copying DNA itself is called replication.
