Reading

1. The phrase "robust ethical frameworks" refers to

Correct answer: B

Rationale: Ethical frameworks are sets of principles and guidelines that ensure responsible AI development and address potential risks, aligning with B.

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. The term "unconditional" in the context of UBI signifies that

Correct answer: C

Rationale: The unconditional aspect of UBI refers to the lack of strings attached to its receipt, aligning with C.

4. Diabetes mellitus is a chronic condition affecting blood sugar control. What is the main type of hormone deficiency associated with type 1 diabetes?

Correct answer: A

Rationale: The correct answer is A: "Insulin." In type 1 diabetes, the main type of hormone deficiency is insulin. Insulin is produced by the pancreas and is crucial for regulating blood sugar levels by helping cells absorb glucose. In individuals with type 1 diabetes, the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas, leading to a deficiency of insulin. This results in uncontrolled high blood sugar levels, which can have serious consequences if not managed properly. Glucagon, estrogen, and testosterone do not play a primary role in the hormone deficiency associated with type 1 diabetes.

5. Two coherent light waves with a slight phase difference interfere. What determines the resulting intensity of the combined wave?

Correct answer: A

Rationale: The intensity of the resulting wave depends on the individual intensities and the phase difference between the interfering waves. Constructive interference leads to higher intensity, while destructive interference leads to lower intensity.

6. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

Correct answer: C

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is 1.5 grams per kilogram of body weight. Protein is essential for muscle repair and growth, and consuming an adequate amount helps support overall muscle health. 1 gram per kilogram of body weight is generally recommended for sedentary individuals, but for those looking to maintain or build muscle mass, a higher intake of 1.5 grams per kilogram of body weight is advised. Consuming too little protein can lead to muscle loss, while consuming too much may strain the kidneys. Therefore, 1.5 grams per kilogram of body weight strikes a balance for most adults looking to support their muscle health.
