1. Which of the following is an effect of high blood pressure?

Correct answer: C

Rationale: The correct answer is C: Renal vessel damage. High blood pressure can lead to damage in blood vessels throughout the body, including the kidneys. When blood vessels in the kidneys are affected, it can impair kidney function and potentially lead to kidney disease. Smoking (Choice A) and excessive dietary salt (Choice B) can contribute to high blood pressure but are not direct effects of high blood pressure itself. Older age (Choice D) is a risk factor for developing high blood pressure but is not a direct effect of high blood pressure.

2. What is the name of the structure that packages DNA in eukaryotic cells?

Correct answer: A

Rationale: - A nucleosome is the basic structural unit of DNA packaging in eukaryotic cells. It consists of DNA wrapped around a core of histone proteins. - Chromatin refers to the complex of DNA and proteins found in the nucleus of a eukaryotic cell, including nucleosomes. - Histones are the proteins around which DNA is wrapped to form nucleosomes. - Centromere is a region of a chromosome where the two sister chromatids are joined and to which spindle fibers attach during cell division.

3. 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.

4. Which of the following substances is a common base found in household products?

Correct answer: B

Rationale: The correct answer is B, Ammonia (NH₃). Ammonia is commonly found in household products and is used in cleaning agents due to its alkaline properties. Sodium chloride (NaCl) is a common salt and not a base. Vinegar is acetic acid, which is acidic in nature. Lemon juice contains citric acid, making it acidic as well. Therefore, ammonia is the only base among the choices provided.

5. Which locations in the digestive system are sites of chemical digestion? I. Mouth II. Stomach III. Small Intestine

Correct answer: D

Rationale: Chemical digestion occurs in all three locations in the digestive system - the mouth, stomach, and small intestine. Enzymes in the saliva break down carbohydrates in the mouth, gastric juices in the stomach help break down proteins, and enzymes in the small intestine further break down macronutrients like carbohydrates, proteins, and fats. The mouth initiates the digestion of carbohydrates, the stomach digests proteins, and the small intestine continues the breakdown of carbohydrates, proteins, and fats. Choice A is incorrect because chemical digestion does occur in the mouth. Choice B is incorrect as both the stomach and small intestine are sites of chemical digestion. Choice C is incorrect as the mouth is also a location of chemical digestion, not just the stomach and small intestine.
