1. Which vitamin requires intrinsic factor from the stomach for proper absorption?

• A. Vitamin A
• B. Vitamin C
• C. Vitamin D
• D. Vitamin B12

Correct answer: D

Rationale: The correct answer is D, Vitamin B12. Vitamin B12 requires intrinsic factor, a glycoprotein produced by the parietal cells in the stomach, for proper absorption in the small intestine. Intrinsic factor binds to B12 and facilitates its absorption in the ileum. Without intrinsic factor, the body cannot effectively absorb Vitamin B12, leading to deficiencies and various health issues. Vitamins A, C, and D do not require intrinsic factor for absorption and have different mechanisms for uptake and utilization within the body.

2. What is the momentum of a car with a mass of 1500 kg moving at a speed of 20 m/s?

• A. 30,000 kg m/s
• B. 1500 kg m/s
• C. 20 kg m/s
• D. Momentum cannot be determined without knowing the direction of motion.

Correct answer: A

Rationale: Momentum is defined as the product of mass and velocity. Momentum = mass x velocity = 1500 kg x 20 m/s = 30,000 kg m/s.

3. Which element is a good conductor of electricity but is not a metal?

• A. Copper
• B. Silver
• C. Graphite
• D. Gold

Correct answer: C

Rationale: While metals are known for their conductivity, some non-metals like graphite also exhibit this property due to their unique electronic structure

4. Which of the following situations represents work being done on an object?

• A. Pushing against a wall without moving it
• B. Carrying a heavy object without lifting it
• C. Lifting a box to place it on a shelf
• D. Holding a book stationary in your hand

Correct answer: c

Rationale: Work is done when a force is applied to move an object over a distance.

5. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

• A. Ovary
• B. Fallopian tube
• C. Uterus
• D. Vagina

Correct answer: C

Rationale: The correct answer is C: Uterus. The uterus, also known as the womb, is a muscular sac in the female reproductive system where a fertilized egg implants and develops into a fetus during pregnancy. It provides nourishment, support, and protection to the developing fetus until birth. The ovaries produce eggs, the fallopian tubes transport eggs to the uterus, and the vagina is the birth canal and the organ of sexual intercourse, but the uterus is specifically responsible for nurturing and protecting the developing fetus.

6. Describe the mechanism by which genes are transmitted from parents to offspring.

• A. Blending of parental genes, resulting in an average of their traits.
• B. Random assortment of alleles during meiosis, leading to unique combinations in each offspring.
• C. Inheritance of solely dominant alleles, masking the influence of recessive ones.
• D. Direct transfer of both parental genomes, creating identical copies of the parents.

Correct answer: B

Rationale: Rationale: A) Blending of parental genes, resulting in an average of their traits, is not an accurate description of how genes are transmitted. In reality, genes are not blended but rather passed down in discrete units. B) Random assortment of alleles during meiosis is the correct mechanism by which genes are transmitted from parents to offspring. During meiosis, homologous chromosomes separate, and alleles are randomly distributed to the gametes, leading to unique combinations of genes in each offspring. C) Inheritance of solely dominant alleles, masking the influence of recessive ones, is not an accurate representation of gene transmission. Offspring inherit alleles from both parents, and the expression of dominant or recessive traits depends on the specific combination of alleles. D) Direct transfer of both parental genomes, creating identical copies of the parents, is not how genes are transmitted. Offspring inherit a unique combination
