ATI TEAS 7 science review Questions
Question 1 of 5
How does polarization affect the intensity of light passing through a polarizing filter?
Correct Answer: B
Rationale: A polarizing filter only allows light waves with a specific orientation (polarization) to pass through while blocking light waves with different orientations. Therefore, light with the same polarization as the filter will pass through, while light with different polarizations will be blocked. This results in a reduction in intensity for light passing through the polarizing filter. Choice A is incorrect because a polarizing filter selectively filters light based on its polarization. Choice C is incorrect as the intensity of light passing through is determined by its polarization, not solely its intensity. Choice D is incorrect because a polarizing filter affects light based on its polarization, not uniformly reducing the intensity for all light passing through.
Question 2 of 5
What is the relationship between work, force, and displacement?
Correct Answer: B
Rationale: Work is directly proportional to both force and displacement. The work done on an object is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. Therefore, work is directly proportional to both force and displacement. Choice A is incorrect because work is not inversely proportional to displacement. Choice C is incorrect because work is not inversely proportional to force. Choice D is incorrect because work is not inversely proportional to both force and displacement.
Question 3 of 5
During embryonic development, all tissues originate from
Correct Answer: D
Rationale: During embryonic development, all tissues originate from the three primary germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various tissues and organs in the developing embryo through a process called gastrulation. Epithelial, muscle, and connective tissues are derived from these germ layers during development. Therefore, choices A, B, and C are incorrect as tissues do not originate from a single type of tissue but rather from the embryonic germ layers which differentiate into various tissues and organs.
Question 4 of 5
Which respiratory structure is responsible for the production of mucus to trap particles and for the movement of cilia to sweep mucus and trapped particles out of the respiratory tract?
Correct Answer: D
Rationale: The respiratory epithelium is the correct answer because it is the tissue lining the respiratory tract responsible for producing mucus to trap particles and containing cilia that sweep the mucus and trapped particles out of the respiratory tract. The trachea, larynx, and bronchi are all structures within the respiratory system but do not specifically carry out the functions described in the question. The trachea is a passage for air, the larynx is involved in sound production and protecting the airway, and the bronchi are airway passages that branch from the trachea to the lungs. Only the respiratory epithelium fits the description of producing mucus and utilizing cilia for particle removal in the respiratory tract.
Question 5 of 5
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.
