1. Which of the following spellings is correct?

• A. Dependant
• B. Dependent
• C. Dependunt
• D. Dependent

Correct answer: D

Rationale: The correct spelling is 'dependent,' meaning someone who relies on another for support. Choice A, 'Dependant,' is a common misspelling. Choice B, 'Dependint,' is incorrect. Choice C, 'Dependunt,' is also incorrect. Therefore, the correct answer is 'Dependent.'

2. What is the scientific name for the common housefly?

• A. Musca domestica
• B. Drosophila melanogaster
• C. Apis mellifera
• D. Anopheles gambiae

Correct answer: A

Rationale: Musca domestica is the scientific name for the common housefly. This species is known for being a common pest found in and around human habitations. Drosophila melanogaster (option B) is a species of fruit fly commonly used in genetic research. Apis mellifera (option C) is the scientific name for the western honeybee. Anopheles gambiae (option D) is a species of mosquito known for being a vector of malaria.

3. Given that three vertices of a parallelogram are (1, 2), (3, 4), and (5, 6), what are the coordinates of the fourth vertex?

• A. (1, 6)
• B. (3, 2)
• C. (5, 2)
• D. (7, 8)

Correct answer: D

Rationale: To find the fourth vertex of a parallelogram, we can use the properties of a parallelogram. Opposite sides of a parallelogram are parallel and equal in length. Therefore, we can determine the fourth vertex by extending the line formed by the first two points. If we extend the line from (1, 2) to (3, 4), we find that it has a slope of 1. This means that extending the line from (3, 4) by the same slope will give us the fourth vertex. By adding 2 units to both x and y coordinates of (5, 6), we get (7, 8) as the coordinates of the fourth vertex. Therefore, the correct answer is (7, 8). Choices A, B, and C are incorrect as they do not satisfy the properties of a parallelogram and the given coordinate points.

4. What energy conversion occurs in a solar cell?

• A. Electrical energy to light energy
• B. Chemical energy to electrical energy
• C. Solar energy to thermal energy
• D. Solar energy to electrical energy

Correct answer: D

Rationale: Solar cells, also known as photovoltaic cells, convert solar energy from sunlight directly into electrical energy through a process called the photovoltaic effect. This process involves the absorption of photons from sunlight, which then generate an electric current. Choice A is incorrect because solar cells do not convert electrical energy into light energy. Choice B is incorrect as solar cells do not involve chemical energy conversion. Choice C is incorrect because solar cells do not primarily convert solar energy into thermal energy. Therefore, the correct answer is D) Solar energy to electrical energy.

5. The framework of bones, cartilage, ligaments, and tendons that provides structure, support, and facilitates movement is part of the:

• A. Muscular system
• B. Skeletal system
• C. Nervous system
• D. Endocrine system

Correct answer: B

Rationale: The skeletal system consists of bones, cartilage, ligaments, and tendons that work together to provide structure, support, protection for internal organs, and facilitate movement. It is responsible for supporting the body's framework and protecting vital organs. The muscular system (option A) consists of muscles that work with the skeletal system to produce movement but does not include bones, cartilage, ligaments, and tendons. The nervous system (option C) is responsible for transmitting signals throughout the body to control movement and other functions. The endocrine system (option D) is a collection of glands that produce hormones to regulate various bodily functions but is not primarily involved in structure, support, and movement as the skeletal system is.
