1. How many bones are included in the human skeletal system?

• A. 412
• B. 103
• C. Over 300
• D. 206

Correct answer: D

Rationale: There are 206 bones in the human skeletal system. This includes bones in the skull, spine, ribs, arms, legs, hands, and feet. The correct answer is 206 because that is the standard number of bones in an adult human body. Choices A, B, and C are incorrect as they do not reflect the accurate count of bones in the human skeletal system.

2. Which part of a plant’s reproductive system is of a different “gender” than the others?

• A. Stamen
• B. Pistil
• C. Stigma
• D. Style

Correct answer: A

Rationale: The stamen is the male reproductive organ of a plant, producing pollen grains. The pistil, consisting of the stigma, style, and ovary, is the female reproductive organ. Therefore, the stamen is of a different 'gender' than the other parts of the plant's reproductive system. The pistil, stigma, and style are all part of the female reproductive system, involved in receiving pollen and supporting fertilization. Stamen is the correct answer as it is the male part of a plant's reproductive system, making it different 'gender-wise' from the female parts.

3. If a test has poor internal consistency, which statement is true?

• A. The test produces different results at different times.
• B. The items do not correlate or measure similar things.
• C. The test produces different results depending on the researcher.
• D. The items never vary even when the test environment changes.

Correct answer: B

Rationale: Correct answer: If a test has poor internal consistency, it means that the items do not correlate or measure similar things. This lack of correlation indicates that the items in the test are not measuring the same underlying construct or concept, leading to unreliable results. Choice A is incorrect because poor internal consistency is not about producing different results at different times but rather about the lack of correlation among items. Choice C is incorrect because the issue lies within the test itself, not with different researchers. Choice D is incorrect because poor internal consistency implies that the items do vary in their measurement, contributing to the unreliability of the test.

4. The renal system consists of all the organs involved in the formation and release of urine and includes the kidneys, ureters, bladder, and urethra.

• A. The digestive system
• B. The reproductive system
• C. The renal system
• D. The kidney system

Correct answer: C

Rationale: The correct term for the system involving the organs responsible for the formation and release of urine is the renal system, not the digestive or reproductive system. The kidneys, ureters, bladder, and urethra are specifically part of the renal system, which is responsible for filtering the blood to remove waste and excess fluids, producing urine, and eliminating it from the body. The other choices, the digestive system and the reproductive system, are not responsible for the formation and release of urine, making them incorrect answers.

5. Which component of the cell contributes to the protection, communication, and passage of substances into and out of the cell?

• A. Nucleus
• B. Cell membrane
• C. Endoplasmic reticulum
• D. Cytoplasm

Correct answer: B

Rationale: The correct answer is the cell membrane. The cell membrane is responsible for protecting the cell, facilitating communication with the external environment, and regulating the passage of substances into and out of the cell. The nucleus (Choice A) is the control center of the cell and houses the genetic material but is not primarily involved in these functions. The endoplasmic reticulum (Choice C) is involved in protein synthesis and lipid metabolism, not primarily in protection or communication. The cytoplasm (Choice D) is the gel-like substance that fills the cell but does not specifically contribute to protection, communication, or substance passage.
