1. Which of the following are properties of a liquid?

Correct answer: D

Rationale: The correct answer is D: 'Takes shape of container.' Liquids exhibit the property of taking the shape of their container while maintaining a fixed volume. This is due to the ability of liquid particles to flow and move freely within the container. Choices A, B, and C are incorrect. Choice A, 'High atomic attraction,' is not a general property of liquids as the level of attraction between liquid particles can vary. Choice B, 'Fixed volume,' is partially correct as liquids do have a fixed volume, but they do not have a fixed shape. Choice C, 'Low pressure,' is not a defining property of liquids.

2. What potential consequences can chromosomal nondisjunction have on offspring?

Correct answer: D

Rationale: - Chromosomal nondisjunction is the failure of homologous chromosomes or sister chromatids to separate properly during cell division, leading to an abnormal number of chromosomes in the resulting cells. - Down syndrome is caused by an extra copy of chromosome 21, resulting from nondisjunction during meiosis. Individuals with Down syndrome have three copies of chromosome 21 instead of the usual two. - Turner syndrome is characterized by the absence of one X chromosome in females, leading to a variety of physical and developmental features. - Klinefelter syndrome features one or more extra X chromosomes in males, typically resulting in infertility and other physical characteristics. Therefore, chromosomal nondisjunction can lead to various genetic disorders such as Down syndrome, Turner syndrome, and Klinefelter syndrome, making option D the correct answer.

3. A substance is only considered acidic if it has a pH less than what?

Correct answer: C

Rationale: A substance is considered acidic if its pH is less than 7. pH values below 7 indicate acidity, while pH values above 7 indicate alkalinity or basicity. Substances with a pH less than 7 are categorized as acidic, not above it. Therefore, a substance is classified as acidic if its pH is less than 7, making choice C the correct answer. Choices A, B, and D are incorrect because a pH of 12, 9, and 4, respectively, are all above 7, and therefore not indicative of acidity.

4. Which of the following is a major factor influencing the distribution of organisms geographically?

Correct answer: D

Rationale: The distribution of organisms geographically is influenced by various factors. The availability of specific types of food sources is crucial as organisms need suitable food sources to survive and thrive in an area. Tolerance of organisms to different temperature ranges is also important, as temperature impacts where species can live. Organisms must withstand temperature conditions to survive. Competition for mates within the same species affects population sizes and dynamics in different areas. Therefore, all these factors collectively influence the distribution of organisms geographically. Choice D, 'All of the above,' is the correct answer because each of the factors mentioned (availability of food sources, tolerance to temperature ranges, and competition for mates) plays a significant role in determining the distribution of organisms in different geographical locations. Choices A, B, and C are incorrect because they each only represent one specific factor that influences distribution, whereas the correct answer encompasses all the major factors mentioned.

5. Which structure in the respiratory system is responsible for gas exchange?

Correct answer: B

Rationale: The alveoli in the lungs are responsible for gas exchange. Alveoli have a rich blood supply and thin walls, enabling the exchange of oxygen and carbon dioxide. Oxygen diffuses into the blood from the alveoli, while carbon dioxide diffuses out. The trachea functions as an air passage, bronchi are the main airways into the lungs, and the diaphragm is the primary muscle involved in breathing by aiding in lung expansion and contraction, but they are not directly responsible for gas exchange like the alveoli.
