1. Where is the gastrocnemius vein in relation to the femoral vein?

Correct answer: A

Rationale: The gastrocnemius vein is located lateral to the femoral vein. In anatomical terms, lateral refers to the direction towards the side of the body or away from the midline. In this case, the gastrocnemius vein is positioned to the side of the femoral vein. The term 'distal' refers to being further away from the point of reference, 'superior' indicates a higher position, and 'ventral' refers to the front or anterior aspect of the body. Therefore, the correct answer is A. Lateral.

2. Which of the following is NOT a characteristic of living organisms?

Correct answer: D

Rationale: A) Made up of cells: All living organisms are composed of one or more cells, a fundamental characteristic of life as defined by cell theory. B) Able to reproduce: Reproduction is a key characteristic of living organisms to pass on genetic information. C) Require energy: Energy is essential for carrying out life processes like growth and maintenance of homeostasis. D) Non-motile: While some living organisms are non-motile, movement is common in many organisms for survival activities like finding food, escaping predators, and responding to the environment. Therefore, being non-motile is not a universal characteristic of living organisms, making it the correct answer in this context.

3. Which enzyme found in saliva is responsible for breaking down carbohydrates into smaller molecules like sugars?

Correct answer: B

Rationale: The correct answer is B. Saliva contains an enzyme called amylase, which specifically targets carbohydrates and breaks them down into smaller molecules like sugars. Pepsin, choice A, is an enzyme found in the stomach that breaks down proteins, not carbohydrates. Lipase, choice C, is responsible for breaking down fats, not carbohydrates. Trypsin, choice D, is an enzyme that breaks down proteins in the small intestine, not carbohydrates. Therefore, choices A, C, and D are incorrect for this question.

4. What is the shape of the DNA molecule?

Correct answer: C

Rationale: The correct answer is C: Double helix. The shape of the DNA molecule is a double helix, a structure first described by James Watson and Francis Crick in 1953. This shape consists of two strands twisted around each other in a spiral. The double helix structure allows DNA to be compactly stored within the cell nucleus and provides stability to the molecule. Options (A) Linear, (B) Circular, and (D) Straight chain are incorrect as they do not accurately represent the shape of the DNA molecule. DNA is not linear but rather forms a twisted double helix; it is not circular like a ring but has a spiral structure, and it is not a straight chain but a twisted ladder-like structure.

5. Which type of reaction builds larger and more complex molecules from smaller ones, requiring energy?

Correct answer: B

Rationale: The correct answer is 'Anabolic reaction.' Anabolic reactions involve the synthesis of larger and more complex molecules from smaller ones, requiring an input of energy, often in the form of ATP. These reactions are essential for processes like growth, repair, and the building of cellular structures. Catabolic reactions, on the other hand, break down larger molecules into smaller ones, releasing energy. Exothermic reactions release heat, while hydrolytic reactions involve the breakdown of molecules with the addition of water. Therefore, choices A, C, and D are incorrect as they do not describe the process of building larger and more complex molecules from smaller ones with the requirement of energy.
