TEAS 7 science practice questions

1. A large geographic area characterized by similar climate, plants, and animals is called a:

Correct answer: C

Rationale: A) Population refers to a group of individuals of the same species living in a specific area. B) Community refers to all the populations of different species living and interacting in a particular area. C) Biome is a large geographic area characterized by similar climate, plants, and animals. Biomes are defined by factors such as temperature, precipitation, and vegetation types. D) Ecosystem refers to a community of living organisms interacting with each other and their physical environment. An ecosystem can be part of a biome.

2. What is the end result of mitosis in animal cells?

Correct answer: A

Rationale: Mitosis is a type of cell division specific to eukaryotic cells that results in the production of two identical daughter cells, each with the same genetic material as the parent cell. This process is crucial for growth, tissue repair, and maintaining a constant number of chromosomes in multicellular organisms. During mitosis, the replicated chromosomes are segregated into two separate nuclei, followed by the division of the cell into two identical daughter cells. Options B, C, and D are incorrect as mitosis does not lead to the production of four haploid cells, a single diploid cell, or a single haploid cell. The correct answer is A because mitosis results in the formation of two daughter cells that are genetically identical to each other and to the parent cell, allowing for growth and replacement of damaged cells in multicellular organisms.

3. Which structure of the endocrine system is responsible for maturing T cells?

Correct answer: C

Rationale: The thymus is the primary gland responsible for the maturation of T cells in the immune system. T cells are a type of white blood cell involved in the immune response. The hypothalamus is primarily involved in hormone regulation and maintaining homeostasis. The pineal gland is responsible for secreting melatonin and regulating the sleep-wake cycle. The thyroid gland plays a key role in metabolism regulation through the production of thyroid hormones. Therefore, the correct answer is the thymus because it is specifically associated with the maturation of T cells, making it essential for proper immune function.

4. What is the name of the outermost layer of the skin?

Correct answer: B

Rationale: The correct answer is B: Epidermis. The epidermis is the outermost layer of the skin, providing a protective barrier against external factors. The dermis is situated beneath the epidermis and contains structures like blood vessels and hair follicles. Subcutaneous tissue, also known as the hypodermis, lies below the dermis and consists mainly of fat tissue, serving functions such as insulation and energy storage. Therefore, choices A, C, and D are incorrect as they do not represent the outermost layer of the skin.

5. What term describes the bending of waves around obstacles or through openings?

Correct answer: C

Rationale: The correct answer is C, Diffraction. Diffraction is the phenomenon that explains the bending of waves around obstacles or through openings. When waves encounter obstacles or pass through openings, they spread out and bend around them. Reflection (Choice A) involves waves bouncing back when they encounter a surface without bending, refraction (Choice B) is the bending of waves when passing from one medium to another due to a change in speed, and absorption (Choice D) is the process of a wave being taken in by a material rather than bending or bouncing.
