Chemistry

1. Which of the following is a strong base commonly used in cleaning products?

Correct answer: A

Rationale: Sodium hydroxide is a strong base commonly used in cleaning products. The other choices are also bases but are not as strong as sodium hydroxide.

2. Which nitrogenous bases pair with each other in DNA?

Correct answer: B

Rationale: Rationale: In DNA, nitrogenous bases pair with each other in a specific manner known as complementary base pairing. Adenine (A) always pairs with Thymine (T), and Cytosine (C) always pairs with Guanine (G). This pairing is essential for maintaining the structure and function of DNA. Therefore, option B is the correct answer as it correctly identifies the nitrogenous bases that pair with each other in DNA.

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

Correct answer: D

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

4. What property of a wave determines its speed in a given medium?

Correct answer: d

Rationale: The speed of a wave is determined by the properties of the medium it travels through.

5. Epithelial tissue, which covers surfaces, is further classified based on the number of cell layers. Simple epithelium has:

Correct answer: B

Rationale: The correct answer is B: 'One layer.' Simple epithelium is characterized by having a single layer of cells. This type of epithelial tissue is found in areas where diffusion, filtration, or absorption are primary functions. Simple epithelium allows for efficient exchange of substances across the cell layer due to its thin structure and close proximity to underlying tissues. Examples of locations where simple epithelium is found include the lining of blood vessels (endothelium) and air sacs of the lungs (alveoli). In contrast, stratified epithelium consists of multiple layers of cells and is commonly found in areas that require protection against mechanical or chemical stress, such as the skin and the lining of the esophagus.

6. Percent (%) is a way to express a fraction with a denominator of 100. 125% can be expressed as a fraction in lowest terms. Which of the following represents 125% as a fraction?

Correct answer: A

Rationale: Percent literally means "out of one hundred." So, 125% is equivalent to 125/100. We can simplify this fraction by dividing the numerator and denominator by 25, resulting in 5/2.
