TEAS 7 science practice questions

1. What is the term for a group of organisms with the same genetic makeup?

Correct answer: B

Rationale: In this context, a clone (option B) is a group of organisms that are genetically identical because they are derived from a single ancestor. A population (option A) refers to a group of individuals of the same species living in the same area. Genotype (option C) refers to the genetic makeup of an individual organism. Species (option D) refers to a group of organisms that can interbreed and produce fertile offspring. Therefore, the most appropriate choice for the question is 'Clone,' as it specifically refers to organisms with the same genetic makeup.

2. What is the term for the time it takes for a wave to complete one full cycle?

Correct answer: C

Rationale: The period of a wave is the time it takes for one complete cycle to occur. It is the duration between two successive points in the wave that are in the same phase. Frequency, on the other hand, refers to the number of cycles of a wave that occur in a given time period. Amplitude represents the maximum displacement of a wave from its equilibrium position. Wavelength is the distance between two consecutive points on a wave that are in phase. Therefore, the correct answer is 'Period' as it specifically refers to the time taken for a wave to complete one full cycle, distinguishing it from the other choices which represent different properties of a wave.

3. How are the motor pathways of the ANS arranged?

Correct answer: B

Rationale: The correct answer is B. The motor pathways of the autonomic nervous system (ANS) are organized with two neurons: a pre-ganglionic neuron that transmits the signal from the central nervous system (CNS) to a ganglion, and a post-ganglionic neuron that conveys the signal from the ganglion to the target organ. This dual-neuron pathway enables the integration and modulation of signals before reaching the target organ, allowing for a more sophisticated and adaptable control system. Choice A is incorrect as it describes a single neuron pathway, which is not characteristic of ANS motor pathways. Choice C is incorrect as it suggests multiple neurons from the CNS to the target organ, which is not the typical arrangement. Choice D is incorrect as it describes a single neuron pathway from the CNS to peripheral ganglia, which does not account for the ganglionic transmission in ANS motor pathways.

4. What accurately describes the Linnaean system of classification?

Correct answer: D

Rationale: The Linnaean system of classification, developed by Carl Linnaeus, is based on a hierarchical ranking system where organisms are grouped into categories based on shared characteristics. This system organizes organisms into a hierarchy of increasingly specific categories, from broad to narrow, such as kingdom, phylum, class, order, family, genus, and species. The emphasis on a hierarchical ranking system allows for systematic organization and classification of a wide variety of organisms based on their similarities and differences, making it easier to study and understand the diversity of life forms. Choice A is incorrect because the Linnaean system is not primarily focused on evolutionary relationships but rather on shared characteristics for classification. Choice B is incorrect because dichotomous keys are tools used for identifying organisms, not the fundamental basis of the Linnaean system. Choice C is incorrect as the Linnaean system categorizes organisms based on shared characteristics, not shared functions.

5. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

Correct answer: C

Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. Therefore, it does not primarily consist of photosynthetic organisms with cell walls made of cellulose. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic, so they do not fit the description. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This accurately describes plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.
