1. What is a contraceptive method that uses hormones to prevent ovulation?

A. Spermicide
B. Barrier method (condom, diaphragm)
C. Combined oral contraceptive pill
D. Intrauterine device (IUD)

Correct answer: C

Rationale: The correct answer is C: Combined oral contraceptive pill. This method uses hormones, such as estrogen and progestin, to prevent ovulation, thicken cervical mucus to block sperm, and thin the uterine lining to prevent implantation of a fertilized egg. Spermicide (A) is a chemical that kills sperm but does not prevent ovulation. Barrier methods (B) like condoms and diaphragms physically block sperm from reaching the egg. Intrauterine devices (IUDs) (D) are inserted into the uterus and work by either releasing hormones or creating a barrier to prevent fertilization, but they do not specifically target ovulation.

2. Nutrients are absorbed into the bloodstream through which part of the digestive system?

A. Stomach
B. Large intestine
C. Small intestine
D. Esophagus

Correct answer: C

Rationale: The correct answer is C: Small intestine. The small intestine is where most of the absorption of nutrients takes place in the digestive system. Its inner lining is covered with tiny finger-like projections called villi, which increase the surface area for absorption. Nutrients such as carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream through the walls of the small intestine. The stomach primarily helps with the initial digestion of food, the large intestine absorbs water and salts, and the esophagus is the tube that carries food from the mouth to the stomach. Therefore, the small intestine is the main site of nutrient absorption in the digestive system.

3. Which word is spelled correctly?

A. Accomodate
B. Acquiesce
C. Percieve
D. Dilema

Correct answer: B

Rationale: Option B is the correct spelling for "to submit or agree without protest."

4. What is the meaning of the idiom "to bite off more than one can chew"?

A. To be overly confident
B. To take on more than one can handle
C. To be easily discouraged
D. To be meticulous in planning

Correct answer: B

Rationale: The idiom warns against undertaking a task exceeding one's capabilities.

5. Which type of epithelial tissue lines the inner lining of your intestines, responsible for absorption?

A. Stratified squamous
B. Simple columnar
C. Stratified cuboidal
D. Transitional epithelium

Correct answer: B

Rationale: The correct answer is B: Simple columnar. Simple columnar epithelial tissue is well-suited for absorption because of its single layer of tall, column-shaped cells with microvilli on the surface, increasing surface area for absorption. This type of tissue is found in the inner lining of the intestines where absorption of nutrients occurs. Stratified squamous epithelium is more protective and found in areas subject to wear and tear, like the skin. Stratified cuboidal and transitional epithelium are not typically involved in absorption processes. Therefore, simple columnar epithelial tissue is the most appropriate choice for lining the inner surface of the intestines for absorption.
