TEAS Test 7 science Questions

Question 1 of 5

Which of the following is NOT a function of the cardiovascular system?

Correct Answer: D

Rationale: The cardiovascular system is responsible for transporting oxygen to cells (A), maintaining blood pressure (B), and carrying waste products to the kidneys for removal (C). Initiating the immune response (D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen, thymus, and lymph nodes. Therefore, option D is the correct answer as it pertains to a function outside the scope of the cardiovascular system, making it the odd one out among the given choices.

Question 2 of 5

Which of the following is an example of a polymer?

Correct Answer: C

Rationale: The correct answer is C, Polyethylene. Polyethylene is a polymer composed of a large number of repeating ethylene units linked together, forming a long-chain molecule, characteristic of polymers. Methane, ethanol, and acetic acid are small organic molecules that do not demonstrate the repeating unit structure typical of polymers. Therefore, they are not examples of polymers.

Question 3 of 5

What is the primary function of the heart?

Correct Answer: C

Rationale: The main function of the heart is to pump blood throughout the body. The heart acts as a muscular pump that circulates blood, delivering oxygen and nutrients to the body's tissues and removing waste products. Option A is incorrect because blood filtration is a function of the kidneys, not the heart. Option B is incorrect as gas exchange occurs in the lungs, not the heart. Option D is also incorrect as hormone production is mainly carried out by endocrine glands, not the heart.

Question 4 of 5

Which type of isomerism arises due to differences in the arrangement of atoms around a double bond?

Correct Answer: C

Rationale: Cis-trans isomerism, also known as geometric isomerism, arises due to differences in the arrangement of atoms around a double bond. In cis isomers, similar groups are on the same side of the double bond, while in trans isomers, similar groups are on opposite sides of the double bond. This type of isomerism is a subset of stereoisomerism, which includes all isomers that have the same connectivity but differ in spatial arrangement. Chain isomerism involves differences in the carbon chain arrangement, functional group isomerism involves different functional groups, and stereoisomerism is a broader category that encompasses isomers with the same connectivity but different spatial arrangement.

Question 5 of 5

Which of the following is NOT a common route of transmission for a sexually transmitted infection (STI)?

Correct Answer: C

Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. Although some STIs can be transmitted through saliva, deep kissing is not a primary mode of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.
