Science TEAS Practice Test Questions
Question 1 of 5
Which of the following is NOT one of the major types of bones in the human body?
Correct Answer: A
Rationale: The correct answer is A: Dense bone. Dense bone is not one of the major types of bones in the human body. Long bones, short bones, and irregular bones are the three major types. Long bones are characterized by being longer than they are wide, like the femur. Short bones are cube-shaped, like the carpals in the wrist. Irregular bones have complex shapes and are typically found in the spine and face. Dense bone is not a separate category but rather a classification based on the density of bone tissue. It refers to the outer layer of compact bone found in all bone types. Therefore, A is the correct answer because dense bone is not a distinct major type of bone in the human body.
Question 2 of 5
If an organism is AB, which of the following combinations in the gametes is NOT possible?
Correct Answer: B
Rationale: The correct answer is B. If an organism is AB, it means they have alleles A and B. In gametes, each gamete carries only one allele. Therefore, gametes with AA are not possible as they lack the B allele. Gametes with AB are possible since they can carry either A or B allele. Gametes with BB are not possible as they lack the A allele. Gametes with AB are possible as they can carry either A or B allele.
Question 3 of 5
Which of the following statements is FALSE regarding the use of qualitative and quantitative data in scientific research?
Correct Answer: B
Rationale: The correct answer is B: Quantitative data is more accurate than qualitative data. This statement is false because the accuracy of data depends on the research question and the methodology used, not on whether it is qualitative or quantitative. Both types of data have their strengths and limitations. Quantitative data is numerical and lends itself to statistical analysis, but it can lack depth and context. Qualitative data, on the other hand, provides rich insights into perspectives and behavior but may be subjective. Therefore, it is essential to use both types of data in scientific research to gain a comprehensive understanding of a research problem.
Question 4 of 5
Long bones are one of the five major types of bones in the human body. Which of the following bones are long bones?
Correct Answer: D
Rationale: The correct answer is D because the ulna, fibula, and humerus are classified as long bones. Long bones are characterized by their elongated shape, with a shaft and two distinct ends. The ulna and humerus are long bones of the upper extremities, while the fibula is a long bone of the lower extremity. A, the sacrum, is a triangular bone at the base of the spine and is classified as a flat bone. B, the clavicle, is also a flat bone that connects the sternum to the scapula. C, the patella, is a sesamoid bone located in the knee joint and is not classified as a long bone. Therefore, the correct answer is D, as the ulna, fibula, and humerus are examples of long bones based on their structure and function.
Question 5 of 5
What type of bond is formed when electrons are transferred between atoms?
Correct Answer: D
Rationale: The correct answer is D: Ionic bond. In an ionic bond, electrons are transferred from one atom to another, resulting in the formation of positively and negatively charged ions that are attracted to each other. This transfer of electrons leads to the creation of a strong bond between the atoms. A: Transfer bond is not a recognized term in chemistry. B: Static bond is not a valid type of bond in chemistry. C: Covalent bond involves the sharing of electrons between atoms, not the transfer of electrons like in an ionic bond.
