TEAS version 7 quizlet science

1. Which of the following is the main organ responsible for regulating blood pressure?

Correct answer: B

Rationale: The kidneys play a crucial role in regulating blood pressure through various mechanisms. One of the key ways the kidneys regulate blood pressure is by controlling the volume of blood in the body. They do this by adjusting the amount of water and sodium excreted in the urine. The renin-angiotensin-aldosterone system, primarily controlled by the kidneys, also plays a significant role in blood pressure regulation. This system helps to maintain blood pressure by regulating blood volume and systemic vascular resistance. While the heart, adrenal glands, and pituitary gland are involved in various aspects of the cardiovascular and endocrine systems, the kidneys are the main organ responsible for regulating blood pressure.

2. Which of the following is NOT a function of the integumentary system?

Correct answer: D

Rationale: The correct answer is D. The production of digestive enzymes is not a function of the integumentary system. The integumentary system is responsible for regulating body temperature, protecting the body from pathogens, and synthesizing vitamin D. Digestive enzymes are produced by organs in the digestive system, such as the pancreas and stomach, and not by the integumentary system.

3. What is the main component of bile, a substance that aids in fat digestion?

Correct answer: C

Rationale: Bile is a digestive fluid produced by the liver and stored in the gallbladder. Bile salts are the main component of bile that aid in the digestion and absorption of fats in the small intestine. Bile salts help emulsify fats, breaking them down into smaller droplets that can be more easily digested by enzymes. Proteins, carbohydrates, and vitamins are not the main components of bile and do not play a significant role in fat digestion. Therefore, the correct answer is 'Bile salts.' Choices A, B, and D are incorrect as they are not the main components of bile and do not contribute to fat digestion.

4. What type of genetic testing can reveal an individual's susceptibility to certain diseases?

Correct answer: D

Rationale: A) Karyotyping is a genetic test that examines an individual's chromosomes to detect abnormalities such as extra or missing chromosomes. It is not typically used to reveal an individual's susceptibility to certain diseases. B) Pharmacogenomics is the study of how genes affect a person's response to drugs. It focuses on how genetic variations can influence drug response, rather than susceptibility to diseases. C) Paternity testing is a genetic test used to determine the biological relationship between a child and an alleged father. It is not used to reveal an individual's susceptibility to diseases. D) Microarray analysis is a type of genetic testing that can reveal an individual's susceptibility to certain diseases by analyzing variations in their DNA. It can identify genetic markers associated with increased risk for specific conditions, allowing for personalized risk assessment and preventive measures.

5. What is a group of organisms of the same species living in a particular area called?

Correct answer: B

Rationale: A) Community refers to all the populations of different species living and interacting in a particular area. Since the question specifies organisms of the same species, community is not the correct answer. B) Population is a group of organisms of the same species living in a particular area. This term specifically refers to individuals of the same species and their interactions within a defined area. C) Ecosystem includes all the living organisms (biotic factors) and non-living components (abiotic factors) in a particular area and their interactions. While populations are part of an ecosystem, the term 'ecosystem' is broader and includes multiple populations. D) Habitat refers to the specific environment where an organism lives, including the physical and biological factors. It is the place where a population or individual organism resides, but it does not specifically refer to a group of organisms of the same species.
