1. The passage lists all of these benefits of omega-3s EXCEPT ___________.

• A. Reduced blood pressure
• B. Less risk of diabetes
• C. Improved memory
• D. Alleviated depression

Correct answer: B

Rationale: The passage mentions reduced blood pressure, improved memory, and alleviated depression as potential benefits of omega-3s but does not mention a reduced risk of diabetes.

2. What is the name of the outermost layer of the skin?

• A. dermis
• B. epidermis
• C. subcutaneous tissue
• D. hypodermis

Correct answer: B

Rationale: The epidermis is the correct answer as it is the outermost layer of the skin. It acts as a protective barrier against environmental factors and helps in regulating moisture balance. The epidermis is also where new skin cells are continuously formed and contains melanocytes responsible for skin pigmentation. Choices A, C, and D are incorrect. The dermis is the layer beneath the epidermis, the subcutaneous tissue is the deepest layer of the skin, and the hypodermis lies below the dermis.

3. The information presented in this article is?

• A. Against eating and drinking
• B. Against drinking alcohol
• C. Against eating rich foods
• D. Unbiased and informative.

Correct answer: D

Rationale: The information presented in the article is unbiased in its approach. While the article highlights the potential issues related to overeating and alcohol abuse, it does not explicitly advocate against eating and drinking, drinking alcohol, or eating rich foods. The primary focus is on the negative consequences of overeating and alcohol abuse, making choice D, 'Unbiased and informative,' the correct answer. Choices A, B, and C are incorrect as they are not supported by the content of the article; it merely discusses the risks associated with overeating and alcohol abuse without taking a stand against them.

4. What effect does increasing the surface area of a reactant have?

• A. Decreases the reaction rate
• B. Has no effect
• C. Increases the reaction rate
• D. Stops the reaction

Correct answer: C

Rationale: Increasing the surface area of a reactant leads to more particles being exposed to the reaction, which in turn increases the reaction rate. This is because a larger surface area provides more sites for collisions between reacting particles, resulting in a higher frequency of successful collisions and thus accelerating the reaction. Choice A, 'Decreases the reaction rate,' is incorrect because increasing surface area actually accelerates the reaction. Choice B, 'Has no effect,' is incorrect as increasing surface area does have a significant effect on the reaction rate. Choice D, 'Stops the reaction,' is incorrect as increasing surface area does not stop the reaction but rather enhances it.

5. When an individual is under stress, hormones are released. Which of the following is not one of the locations where hormones are released when under stress?

• A. Parathyroid gland
• B. Adrenal cortex
• C. Posterior pituitary
• D. Hypothalamus

Correct answer: A

Rationale: The parathyroid gland is not a location where hormones are typically released during stress. It primarily regulates calcium levels in the blood through the release of parathyroid hormone (PTH). On the other hand, the adrenal cortex releases hormones like cortisol in response to stress, the posterior pituitary releases oxytocin and antidiuretic hormone, and the hypothalamus plays a crucial role in coordinating stress responses through the release of corticotropin-releasing hormone (CRH). Therefore, the parathyroid gland is the correct answer as it is not directly involved in the stress response pathway.
