ATI TEAS 7

TEAS Test 7 science quizlet

1. Which muscular tube carries urine from the kidneys to the bladder?

A. Nephron
B. Ureter
C. Urethra
D. Glomerulus

Correct answer: B

Rationale: The correct answer is B: Ureter. The ureter is the muscular tube that carries urine from the kidneys to the bladder. The nephron is the functional unit of the kidney responsible for filtering blood and producing urine. The urethra is the tube that carries urine from the bladder out of the body. The glomerulus is a network of capillaries in the nephron where filtration of blood occurs.

2. What ethical considerations are associated with the potential use of CRISPR-Cas9 technology in humans?

A. Concerns about unintended consequences on the genome and potential off-target effects.
B. Debates on modifying the human germline and potential eugenic implications.
C. Accessibility and affordability of the technology, ensuring equitable access to benefits.
D. Risks associated with CRISPR-Cas9 editing germline cells and potential long-term impacts.

Correct answer: B

Rationale: The correct answer is B. CRISPR-Cas9 technology allows precise editing of germline cells, raising ethical concerns about modifying the human gene pool. This includes potential eugenic implications, debates on altering future generations, and the moral implications of such genetic modifications. Choice A discusses unintended consequences and off-target effects, but the primary ethical consideration with CRISPR-Cas9 technology relates to altering the human germline. Choices C and D, while important factors, are not the central ethical dilemmas associated with using CRISPR-Cas9 technology in humans.

3. What function do genes serve in the relationship between parents and offspring?

A. Genes enable hereditary information to be passed from parents to offspring.
B. Genes prohibit hereditary information from being passed from parents to offspring.
C. Genes enable environmental factors to affect parents and offspring.
D. Genes serve no function in the relationship between parents and offspring.

Correct answer: A

Rationale: Genes play a crucial role in passing hereditary information from parents to offspring, ensuring the transmission of genetic traits. This process forms the basis of inheritance and genetic continuity between generations. Choice B is incorrect as genes do not prohibit but rather facilitate the transmission of hereditary information. Choice C is incorrect because genes primarily transmit genetic information, while the influence of environmental factors is separate. Choice D is incorrect as genes are fundamental in genetic inheritance and the relationship between parents and offspring.

4. What is the main function of the lungs?

A. To transport oxygen and nutrients throughout the body
B. To coordinate movement and sensory information
C. To filter waste products from the blood
D. To exchange oxygen and carbon dioxide between the body and the environment

Correct answer: D

Rationale: The main function of the lungs is to exchange oxygen and carbon dioxide between the body and the environment. This process occurs through the alveoli in the lungs where oxygen from inhaled air enters the bloodstream, and carbon dioxide is removed from the bloodstream and exhaled. Option A is incorrect as the transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, not the lungs. Option B is incorrect as coordinating movement and sensory information is a function of the nervous system, not the lungs. Option C is incorrect as filtering waste products from the blood is primarily the role of the kidneys, not the lungs. Therefore, the correct answer is D.

5. What property of a wave determines the loudness of sound when heard by the human ear?

A. Frequency
B. Amplitude
C. Wavelength
D. Velocity

Correct answer: B

Rationale: The amplitude of a wave determines the loudness of sound when heard by the human ear. The greater the amplitude of a sound wave, the louder the sound will be perceived. Frequency (Choice A) refers to the number of wave cycles in a given time period. Wavelength (Choice C) is the distance between two corresponding points on a wave. Velocity (Choice D) is the speed at which the wave travels and does not directly affect the loudness of sound perceived by the human ear.
