1. What is the process of a fertilized egg attaching itself to the uterine lining called?

• A. Ovulation
• B. Implantation
• C. Parturition
• D. Menstruation

Correct answer: B

Rationale: Implantation is the correct answer. It is the process in which a fertilized egg attaches itself to the uterine lining, where it will develop into an embryo and eventually a fetus. Ovulation, on the other hand, is the release of an egg from the ovary. Parturition refers to the process of giving birth, while menstruation is the shedding of the uterine lining if fertilization does not occur. Therefore, the process described in the question specifically pertains to implantation.

2. Which of the following terms refers to the process of breaking large molecules into smaller molecules to provide energy?

• A. Metabolism
• B. Bioenergetics
• C. Anabolism
• D. Catabolism

Correct answer: D

Rationale: The correct answer is 'D: Catabolism.' Catabolism specifically involves breaking down large molecules into smaller ones to release energy. It is the opposite of anabolism, which is the process of building larger molecules from smaller ones. 'Metabolism' (choice A) is a broader term that encompasses all chemical processes in an organism, including anabolism and catabolism. 'Bioenergetics' (choice B) refers to the flow and transformation of energy in a biological system, not specifically the breakdown of molecules for energy.

3. What is the anatomical term for the back of the body? Example: Shoulder blade.

• A. Anterior
• B. Superior
• C. Posterior
• D. Inferior

Correct answer: C

Rationale: The correct answer is C: Posterior. 'Posterior' is the anatomical term that refers to the back of the body. It is the opposite of 'anterior,' which refers to the front of the body. 'Superior' typically describes a structure that is positioned above another structure, while 'inferior' refers to a structure that is below another. In this case, the term 'posterior' specifically indicates the back of the body, making it the most appropriate choice among the options provided.

4. What happens to the momentum of an object when there is no external force acting upon it?

• A. Momentum increases
• B. Momentum decreases
• C. Momentum remains constant
• D. Momentum becomes zero

Correct answer: C

Rationale: When there is no external force acting upon an object, the law of conservation of momentum dictates that the momentum of the object remains constant. This means that the momentum does not increase or decrease; it stays the same. Choice A is incorrect because momentum does not increase. Choice B is incorrect because momentum does not decrease. Choice D is incorrect as momentum does not become zero; it remains constant as per the conservation law. Therefore, the correct answer is C, as the object's momentum is unchanged in the absence of external forces.

5. Which organ stores and concentrates bile?

• A. Liver
• B. Gallbladder
• C. Pancreas
• D. Stomach

Correct answer: B

Rationale: The correct answer is B: Gallbladder. The gallbladder is the organ that stores and concentrates bile produced by the liver. Bile is essential for the digestion of fats in the small intestine. The liver produces bile, which is then stored and concentrated in the gallbladder until it is released into the small intestine when needed. Choices A, C, and D are incorrect because the liver produces bile, the pancreas produces digestive enzymes, and the stomach is primarily involved in the digestion of food through acid secretion and mechanical processes, not in storing bile.
