1. What is correct about the hormones that stimulate male and female organs to produce male and female sex hormones?

A. Female organs are stimulated by female hormones and male organs by male hormones.
B. The same hormones that produce male or female sex characteristics stimulate the organs.
C. The same hormones stimulate both male and female organs to produce sex hormones.
D. The hypothalamus stimulates the pituitary gland's secretion of male and female hormones.

Correct answer: C

Rationale: The correct answer is C. The same hormones stimulate both male and female organs to produce sex hormones. Hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) are produced by the pituitary gland and act on the ovaries in females and the testes in males to stimulate the production of sex hormones (estrogen and progesterone in females, testosterone in males). Therefore, the same hormones stimulate both male and female organs to produce sex hormones. Choices A, B, and D are incorrect because they do not accurately describe the relationship between hormones and the stimulation of male and female organs to produce sex hormones.

2. What is the tough, fibrous connective tissue that attaches muscle to bone?

A. Fascia
B. Perimysium
C. Tendon
D. Ligament

Correct answer: C

Rationale: Tendons are the correct answer as they are the tough, fibrous connective tissues that attach muscle to bone. They play a crucial role in transmitting the forces generated by muscle contraction to the bones, facilitating movement. Fascia surrounds muscles and provides support, perimysium is the connective tissue sheath around muscle fibers, and ligaments connect bone to bone, stabilizing joints, which makes them distinct from tendons.

3. Which of the following is a function of the skeletal system?

A. To produce red blood cells
B. To provide structural support
C. To transport nutrients
D. To store fat

Correct answer: B

Rationale: The correct answer is B: To provide structural support. The skeletal system is primarily responsible for supporting the body's structure, protecting internal organs, facilitating movement, and storing minerals. While bones do play a role in producing red blood cells (hematopoiesis) in the bone marrow, the main function related to the question is providing structural support. Choices C and D are incorrect as the skeletal system is not involved in transporting nutrients or storing fat. The main functions of the skeletal system are related to support, protection, movement facilitation, mineral storage, and hematopoiesis.

4. Which type of nutrients require minimal digestion before absorption?

A. Carbohydrates
B. Proteins
C. Fats
D. Vitamins

Correct answer: D

Rationale: A) Carbohydrates: Carbohydrates require digestion by enzymes in the mouth, stomach, and small intestine before they can be broken down into simple sugars for absorption. B) Proteins: Proteins need to be broken down into amino acids by stomach acid and digestive enzymes in the stomach and small intestine before they can be absorbed. C) Fats: Fats require bile from the gallbladder to emulsify them into smaller droplets for enzymes to break them down into fatty acids and glycerol for absorption. D) Vitamins: Vitamins are organic compounds that are already in a form that can be readily absorbed by the body without extensive digestion. They are absorbed directly into the bloodstream from the small intestine and do not require significant breakdown before absorption.

5. How can you predict the charge of an ion formed by an element based on its position on the periodic table?

A. Look for elements with similar atomic weights
B. Identify the group number, which often indicates the typical ionic charge
C. Identify the period number to determine the ionic charge
D. Analyze the element's position within the group

Correct answer: B

Rationale: The group number of an element on the periodic table often indicates the typical ionic charge it will form. Elements in the same group tend to have similar chemical properties, including the tendency to gain or lose electrons to achieve a stable electron configuration. This predictable pattern allows us to anticipate the charge of an ion formed by an element based on its position in the periodic table. Choices A, C, and D are incorrect because predicting the charge of an ion is primarily based on the element's group number, which reflects its valence electrons and typical ionic charge. Atomic weight (Choice A) and period number (Choice C) do not directly correlate with the ionic charge prediction, and analyzing the element's position within the group (Choice D) is less relevant than identifying the group number itself.
