1. What is the function of the pituitary gland?

• A. Produces hormones that regulate growth and metabolism
• B. Filters blood and removes waste products
• C. Stores and releases bile
• D. Produces red blood cells

Correct answer: A

Rationale: The pituitary gland is often referred to as the "master gland" because it controls the activity of many other endocrine glands in the body. It is located at the base of the brain and produces a variety of hormones that regulate various bodily functions, including growth, metabolism, reproduction, and blood pressure.

2. A kite has a top base of 20cm, a bottom base of 30cm, and two equal side lengths of 15cm. What is its perimeter?

• A. 55cm
• B. 65cm
• C. 70cm
• D. 80cm

Correct answer: C

Rationale: Add the lengths of all sides: perimeter = top base + bottom base + 2 * side length = 20cm + 30cm + 2 * 15cm = 70cm.

3. What phenomenon occurs when two identical waves are perfectly aligned and reinforce each other?

• A. Refraction
• B. Reflection
• C. Diffraction
• D. Constructive interference

Correct answer: d

Rationale: Constructive interference happens when identical waves meet in phase, resulting in a wave with increased amplitude.

4. Identify the compound-complex sentence in the following options:

• A. The baker decorated the cake, and then he presented it proudly.
• B. Although it was raining, the children played outside.
• C. When the sun rises, the birds begin to sing.
• D. He enjoyed reading the book because it was suspenseful.

Correct answer: D

Rationale: A compound-complex sentence contains at least two independent clauses and at least one dependent clause.

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. The fossil record shows that dinosaurs with feathers existed millions of years before birds. This is evidence for

• A. Convergent evolution (unrelated organisms evolving similar traits)
• B. Divergent evolution (related organisms evolving different traits)
• C. Coevolution (two species influencing each other's evolution)
• D. The extinction of dinosaurs due to an asteroid impact

Correct answer: A

Rationale: Rationale: The fossil record indicating that dinosaurs had feathers before birds suggests convergent evolution. Convergent evolution occurs when unrelated organisms independently evolve similar traits to adapt to similar environmental pressures. In this case, both dinosaurs and birds developed feathers for flight or insulation purposes, even though they are not closely related. This evidence supports the concept of convergent evolution rather than divergent evolution, coevolution, or the extinction of dinosaurs due to an asteroid impact.
