TEAS 7 science quizlet

1. A routine urinalysis is a common diagnostic test. What does a urinalysis typically evaluate?

A. Blood sugar levels
B. Presence of white blood cells (indicating possible infection)
C. Kidney function
D. All of the above

Correct answer: D

Rationale: A routine urinalysis evaluates multiple components of urine, including blood sugar levels, the presence of white blood cells indicating a possible infection, and kidney function. Blood sugar levels are assessed to monitor for conditions like diabetes. The presence of white blood cells is checked to detect possible urinary tract infections. Kidney function is evaluated by assessing markers like creatinine and protein levels. Therefore, all of the above options are typically evaluated in a urinalysis, making choice D the correct answer.

2. What does 'monophyletic' mean in the context of classification?

A. A group with a single representative organism
B. A group with diverse and unrelated members
C. A group with similar functions but different origins
D. A group descended from a common ancestor

Correct answer: D

Rationale: In the context of classification, 'monophyletic' refers to a group that includes a common ancestor and all of its descendants. This group shares a single evolutionary origin and forms a complete branch on a phylogenetic tree. Monophyletic groups are considered natural and valid taxonomic units because they reflect evolutionary relationships accurately. Option D is the correct choice as it accurately defines the term 'monophyletic' in the context of classification. Choices A, B, and C are incorrect. Choice A is incorrect because 'monophyletic' does not refer to a group with a single representative organism but rather a group descended from a common ancestor. Choice B is incorrect as a monophyletic group consists of related, not diverse and unrelated, members. Choice C is incorrect as a monophyletic group includes descendants from a common ancestor, not just organisms with similar functions but different origins.

3. Which of the following statements is FALSE?

A. An organelle is a specialized structure in a cell, such as a ribosome.
B. An organ is made up of different types of tissues that work together to perform specific functions.
C. Organ systems are two or more organs performing similar functions.
D. A tissue contains a variety of cells that work together to perform a specific function.

Correct answer: B

Rationale: The statement provided in Option B is FALSE. Organs are actually made up of different types of tissues that work together to perform specific functions, rather than being composed of similar tissues. Organs consist of various tissues, each with their own specialized functions that collectively contribute to the overall function of the organ. Options A, C, and D are true statements. Option A correctly defines an organelle as a specialized structure in a cell, like a ribosome. Option C accurately describes organ systems as multiple organs working together to perform related functions. Option D correctly explains that a tissue is composed of different cells working together to carry out a specific function.

4. What is the name of the growth plates in children's bones where new bone tissue is formed?

A. Epiphyses
B. Diaphysis
C. Periosteum
D. Medullary cavity

Correct answer: A

Rationale: The correct answer is A: Epiphyses. Epiphyses are cartilaginous areas found at the ends of long bones, enabling growth and bone lengthening during childhood and adolescence. The diaphysis refers to the main shaft of a long bone. The periosteum is the outer bone layer responsible for nourishment and aiding in bone repair. The medullary cavity is the central cavity within the diaphysis that contains bone marrow but is not involved in new bone tissue formation.

5. Which type of joint allows for the widest range of motion, similar to the shoulder joint?

A. Hinge joint
B. Ball-and-socket joint
C. Gliding joint
D. Fixed joint

Correct answer: B

Rationale: The correct answer is B: Ball-and-socket joint. Ball-and-socket joints, like the shoulder joint, allow for the widest range of motion in multiple directions. This type of joint consists of a rounded bone (the 'ball') fitting into a cup-like socket, enabling movements such as flexion, extension, abduction, adduction, and rotation. Choice A, Hinge joint, allows movement in one plane, like a door hinge, and does not offer the same range of motion as a ball-and-socket joint. Choice C, Gliding joint, permits limited motion in various directions but not as wide as a ball-and-socket joint. Choice D, Fixed joint, does not allow any motion as it is immovable, unlike the shoulder joint which is highly mobile.
