Anatomy

1. Which of the following joints allows for side-to-side bending movements?

Correct answer: C

Rationale: The correct answer is C: Gliding joint. Gliding joints are found where the bones meet and allow for limited side-to-side and back-and-forth movements. These joints have flat or slightly curved surfaces that glide against each other, enabling smooth motion in multiple directions. Hinge joints (A) allow for movement in one plane like a door hinge, ball-and-socket joints (B) allow for a wide range of motion in multiple directions, and saddle joints (D) allow for back-and-forth and side-to-side movements but are primarily designed for flexion and extension like the joint at the base of the thumb.

2. In what way does spindle fiber dynamics and microtubule attachment regulate cell cycle checkpoints?

Correct answer: D

Rationale: Rationale: A) Misaligned chromosomes fail to attach to microtubules, triggering a delay in anaphase onset: During cell division, proper attachment of chromosomes to spindle fibers is crucial for accurate segregation of genetic material. If chromosomes are not correctly attached to microtubules, it can lead to misalignment, which triggers a delay in anaphase onset. This delay allows the cell to correct any errors before proceeding with cell division. B) The presence of unattached kinetochores on the centromeres sends a signal to pause cell cycle progression: Kinetochores are protein structures located at the centromere of chromosomes and are responsible for attaching chromosomes to spindle fibers. When kinetochores are unattached or improperly attached to microtubules, it sends a signal to the cell to pause cell cycle progression. This pause allows the cell to ensure that all chromosomes are properly aligned before proceeding with cell division.

3. What is the relationship between work and energy?

Correct answer: d

Rationale: Work is the process that changes an object's energy from one form to another or transfers it from one object to another.

4. The involuntary reflex arc that withdraws your hand from a hot object involves the:

Correct answer: C

Rationale: The correct answer is C: 'Both CNS and PNS'. This is because the reflex arc involves both the central nervous system (CNS) and the peripheral nervous system (PNS). The sensory neurons in the PNS detect the stimulus (hot object), then send signals to the spinal cord in the CNS. The spinal cord processes the information and immediately sends a motor response signal back out through the PNS to move the hand away from the hot object. This rapid and involuntary response demonstrates the coordination between the CNS and PNS in executing the reflex arc.

5. 7 is divisible by which of the following numbers?

Correct answer: D

Rationale: Rationale: 1. 7 is divisible by 1 because every number is divisible by 1. 2. 7 is divisible by 7 because any number is divisible by itself. 3. 7 is not divisible by 2 because 7 is an odd number and not divisible by 2. 4. 7 is not divisible by 3 because the sum of the digits of 7 (7) is not divisible by 3. Therefore, 7 is divisible by 1, 7, and itself (7), making the correct answer D) 2, 3, and 7.

6. Reactions requiring light energy to proceed are classified as:

Correct answer: C

Rationale: The correct answer is C: "Photochemical reactions." Photochemical reactions are a type of chemical reaction that requires light energy to proceed. During a photochemical reaction, light energy is absorbed by a substance, leading to changes in its chemical structure or properties. This process is different from combustion reactions (A), which involve the rapid combination of a fuel with oxygen to release heat and light energy. Endothermic reactions (B) absorb heat energy, not light energy, to proceed. Double displacement reactions (D) involve the exchange of ions between reactants, but do not specifically require light energy to occur. Therefore, the most appropriate classification for reactions requiring light energy is photochemical reactions.
