Practice Science TEAS Test
1. Which part of the brain regulates body temperature, hunger, and thirst?
- A. Cerebellum
- B. Hypothalamus
- C. Thalamus
- D. Medulla oblongata
Correct answer: B
Rationale: The correct answer is the Hypothalamus. The hypothalamus is a crucial part of the brain that regulates various essential functions to maintain homeostasis. It controls body temperature, hunger, thirst, and plays a key role in the autonomic nervous system. The cerebellum is primarily involved in coordinating movement and balance, the thalamus acts as a relay station for sensory information, and the medulla oblongata is responsible for vital functions like breathing and heart rate. Therefore, choices A, C, and D are incorrect as they do not govern the specific functions mentioned in the question.
2. What are apocrine and eccrine?
- A. Blood vessel
- B. Cell types
- C. Hormones
- D. Sweat glands
Correct answer: D
Rationale: Apocrine and eccrine refer to types of sweat glands in the human body. Apocrine sweat glands are larger and located in areas like the armpits and groin, producing a thicker secretion that can be associated with body odor. Eccrine sweat glands are found throughout the skin and are responsible for regulating body temperature through the production of sweat. Understanding the functions and locations of these glands is essential in comprehending the body's thermoregulation processes.
3. An FBI agent has spent her career studying individual serial killers. From this data, she creates a theory about the traits of these killers. What type of reasoning has she used?
- A. Deductive Reasoning
- B. Conductive Reasoning
- C. Quantitative Reasoning
- D. Inductive Reasoning
Correct answer: D
Rationale: The correct answer is D: Inductive Reasoning. Inductive reasoning involves drawing a general conclusion from specific observations or data, which fits the scenario described where the FBI agent has studied individual serial killers and formulated a theory about their traits based on this specific data. Deductive reasoning (choice A) starts with general information and applies it to a specific case, which is not the case here. Conductive reasoning (choice B) and quantitative reasoning (choice C) are not relevant to the scenario provided.
4. Testosterone is a crucial hormone in the male reproductive system. What is its primary function?
- A. Egg production
- B. Sperm production and development
- C. Regulation of the menstrual cycle
- D. Milk production
Correct answer: B
Rationale: Testosterone is a hormone primarily produced in the testes of males and is responsible for the development of male reproductive tissues, including the testes and prostate. Its primary function is the production and maturation of sperm cells, as well as the development of secondary sexual characteristics in males. Choice A, 'Egg production,' is incorrect as testosterone is not involved in the production of eggs. Choice C, 'Regulation of the menstrual cycle,' is incorrect because testosterone is not responsible for regulating the menstrual cycle, which is primarily governed by female hormones. Choice D, 'Milk production,' is incorrect as testosterone does not play a role in milk production, which is associated with other hormones like prolactin in females.
5. What is the function of the stratified cuboidal epithelium lining the salivary glands?
- A. Protection
- B. Gas exchange
- C. Secretion
- D. Absorption
Correct answer: C
Rationale: The correct answer is C: Secretion. The stratified cuboidal epithelium lining the salivary glands is responsible for secretion. This type of epithelium, made of multiple layers of cube-shaped cells, is specialized for secretion and protection. In the salivary glands, these cells secrete saliva to aid in the digestion process. Choice A, Protection, is incorrect because while the epithelium does provide some level of protection, its primary function in the salivary glands is secretion. Choice B, Gas exchange, is incorrect as the salivary glands are not involved in gas exchange processes. Choice D, Absorption, is also incorrect as the main role of this epithelium in the salivary glands is not absorption but rather secretion of saliva.
