1. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.

2. What is the scientific term for the monthly cycle in females that prepares the body for potential pregnancy?

Correct answer: B

Rationale: The correct answer is B: Menstrual cycle. The menstrual cycle is the scientific term for the monthly cycle in females that prepares the body for potential pregnancy. This cycle involves various phases, including the release of an egg from the ovary (ovulation), thickening of the uterine lining in preparation for a fertilized egg, and shedding of the uterine lining if pregnancy does not occur (menstruation). Choices A, C, and D are incorrect. Option A, Ovulation cycle, only refers to the specific phase of egg release from the ovary. Option C, Implantation cycle, pertains to the process of the fertilized egg attaching to the uterine wall. Option D, Gestation cycle, denotes the period of fetal development during pregnancy, which is distinct from the monthly cycle preparing the body for potential pregnancy.

3. Which of the following organs is responsible for churning and mechanically breaking down food?

Correct answer: C

Rationale: The correct answer is C, the stomach. The stomach is responsible for churning and mechanically breaking down food. It contains muscles that contract and relax to mix food with digestive juices, breaking it down into smaller particles. This mechanical digestion process helps prepare the food for further digestion and absorption in the small intestine. The small intestine is primarily responsible for the absorption of nutrients, not for mechanical digestion. The large intestine absorbs water and salts, and the esophagus is a muscular tube that transports food from the mouth to the stomach, not involved in churning or breaking down food.

4. Which of the following is NOT a common symptom of pregnancy?

Correct answer: D

Rationale: The correct answer is D, 'Loss of appetite.' Loss of appetite is not a common symptom of pregnancy. In fact, many pregnant individuals experience an increase in appetite due to hormonal changes and increased energy needs during pregnancy. Fatigue, nausea, and increased urination are more commonly reported symptoms during pregnancy. Fatigue is often experienced due to hormonal changes and the body's increased metabolic demands during pregnancy. Nausea, commonly known as morning sickness, is a well-known symptom experienced by many pregnant individuals. Increased urination is a common symptom in pregnancy due to hormonal changes leading to increased blood flow to the kidneys and increased fluid processing by the body.

5. Blood type is a trait determined by multiple alleles, with IA coding for A blood, IB coding for B blood, and i coding for O blood being recessive. If an individual with A heterozygosity and an O individual have a child, what is the probability that the child will have A blood?

Correct answer: B

Rationale: When an A heterozygote individual (IAi) and an O individual (ii) have a child, there are four possible combinations of alleles that the child can inherit: IA from the A parent and i from the O parent; IA from the A parent and i from the O parent; i from the A parent and i from the O parent; i from the A parent and i from the O parent. Out of these combinations, 50% of the offspring will inherit the A allele from the A parent, resulting in A blood type. Therefore, the correct answer is 50%. Choice A is incorrect because the probability is not 25%. Choice C is incorrect as it overestimates the likelihood. Choice D is incorrect as it suggests a certainty which is not the case in genetics.
