TEAS Test 7 science quizlet
1. What is the main factor limiting population growth in K-strategists?
- A. Predation
- B. Availability of resources
- C. Competition
- D. Disease
Correct answer: B
Rationale: K-strategists are species with a low reproductive rate that invest more resources in raising fewer offspring. These species typically live in stable environments with limited resources. The main factor limiting population growth in K-strategists is the availability of resources such as food, shelter, and space. When resources are scarce, K-strategists may struggle to find enough to support their population size, leading to reduced reproductive success and population growth. While predation, competition, and disease can also impact population growth, the primary limiting factor for K-strategists is the availability of resources.
2. What is bile, where is it produced, where is it stored, and what is its function?
- A. Produced in the pancreas, stored in the liver, aids in digestion
- B. Produced in the liver, stored in the gallbladder, aids in fat digestion
- C. Produced in the stomach, stored in the pancreas, neutralizes acid
- D. Produced in the gallbladder, stored in the liver, breaks down proteins
Correct answer: B
Rationale: Bile is a digestive fluid produced in the liver, stored in the gallbladder, and it aids in the digestion of fats by emulsifying them. Emulsification helps to break down fats into smaller particles, facilitating their digestion by enzymes in the small intestine. Choice A is incorrect because bile is not produced in the pancreas, and it is not stored in the liver. Choice C is incorrect as bile is not produced in the stomach, and it does not neutralize acid. Choice D is also incorrect as bile is not produced in the gallbladder, and its primary function is not to break down proteins.
3. How many lobes does the right lung have?
- A. 1
- B. 2
- C. 3
- D. 4
Correct answer: C
Rationale: The correct answer is C: 3. The right lung consists of three lobes: the upper, middle, and lower lobes. This distinction is vital as the left lung only has two lobes, the upper and lower lobes. Understanding the anatomical variances between the lobes of the right and left lungs is crucial for comprehending respiratory physiology and its clinical implications in medical practice. Choices A, B, and D are incorrect because the right lung does not have 1, 2, or 4 lobes. It is essential to differentiate between the lobes of the right and left lungs to have a comprehensive understanding of pulmonary anatomy.
4. A symbiotic relationship where one organism benefits and the other is not harmed is called:
- A. Mutualism
- B. Commensalism
- C. Parasitism
- D. Predation
Correct answer: B
Rationale: B) Commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. This is the relationship described in the question. The correct answer is Commensalism because it specifically fits the scenario where one organism benefits without affecting the other. A) Mutualism: In mutualism, both organisms involved benefit from the relationship. C) Parasitism: In parasitism, one organism benefits at the expense of the other organism, which is harmed. D) Predation: In predation, one organism (predator) kills and consumes another organism (prey) for food.
5. Classifications of human tissues exclude:
- A. Epithelial tissue
- B. Nervous tissue
- C. Adipose tissue (a specialized form of connective tissue)
- D. Bony tissue
Correct answer: D
Rationale: The correct answer is D: Bony tissue. Classifications of human tissues typically include epithelial tissue, nervous tissue, and connective tissue types such as adipose tissue. Bony tissue, also known as bone tissue, is a specialized form of connective tissue that provides structural support and protection for the body. Therefore, it is not excluded from classifications of human tissues. Choices A, B, and C are valid types of human tissues and are correctly included in classifications of human tissues.
