ATI TEAS 7 Science Practice Test Questions
Question 1 of 5
What function do genes serve 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.
Question 2 of 5
Two nursing students will be completing a scientific experiment measuring the mass of chewed gum after one-minute chewing increments. Which lab equipment will the students most likely use?
Correct Answer: A
Rationale: The correct answer is A: Triple beam balance. A triple beam balance is the most suitable lab equipment for measuring mass accurately, which is necessary for this experiment. An anemometer measures wind speed, a hot plate is used for heating substances, and a microscope is used for magnifying objects, none of which are relevant to measuring the mass of chewed gum.
Question 3 of 5
In the suburban neighborhood of Northwoods, there has been a large population of deer, and residents have complained about them eating flowers and garden plants. What would be a logical explanation for the large increase in the deer population over the last two seasons?
Correct Answer: B
Rationale: The correct answer is B because a decrease in natural predators can lead to an increase in the deer population as there are fewer predators to control their numbers. This explanation aligns with the situation described in the question, where the deer population has increased, causing issues for residents. Choice A is incorrect because an increase in food sources would not directly explain the increase in the deer population. Choice C is incorrect as it introduces a new factor of migration which is not mentioned in the question. Choice D is incorrect as an increase in hunting licenses sold would likely have the opposite effect on the deer population.
Question 4 of 5
Which of the following statements accurately characterizes the relationship between genes and chromosomes?
Correct Answer: B
Rationale: The correct answer is B: Each chromosome contains multiple genes. Genes, which are segments of DNA, are located on chromosomes and carry hereditary information. Chromosomes contain many genes, indicating that genes are part of the structure of chromosomes. Choice A is incorrect because genes do not contain chromosomes; rather, they are located on chromosomes. Choice C is incorrect as genes and chromosomes are distinct entities with different functions. Choice D is incorrect because genes and chromosomes are related but not in equal numbers; chromosomes contain multiple genes, but the number of genes can vary between chromosomes.
Question 5 of 5
Which of the following substances is NOT a product of cellular respiration?
Correct Answer: C
Rationale: The correct answer is C. Oxygen is not a product of cellular respiration; instead, it is consumed during the process. During cellular respiration, glucose is broken down in the presence of oxygen to produce energy in the form of ATP, carbon dioxide, and water. Carbon dioxide is released as a waste product, water is a byproduct of the chemical reactions, and ATP is the energy currency used by cells. Therefore, options A, B, and D are all products or outcomes of cellular respiration, while oxygen is a reactant.
