TEAS Test 7 science Questions
Question 1 of 5
Adipose tissue, also known as fat, serves multiple functions. Which of these is NOT a function of adipose tissue?
Correct Answer: D
Rationale: Adipose tissue serves multiple functions in the body, including insulation to regulate body temperature, energy storage in the form of triglycerides, and hormone production such as leptin and adiponectin. Adipose tissue does not directly participate in muscle movement. Muscle movement is primarily carried out by skeletal muscle tissue, which is responsible for voluntary movements and locomotion. Therefore, the correct answer is D, as adipose tissue is not involved in muscle movement.
Question 2 of 5
Which of the following is NOT a common symptom of pregnancy?
Correct Answer: D
Rationale: The correct answer is D, 'Loss of appetite.' Loss of appetite is not a common symptom of pregnancy. In fact, many pregnant individuals experience an increase in appetite due to hormonal changes and increased energy needs during pregnancy. Fatigue, nausea, and increased urination are more commonly reported symptoms during pregnancy. Fatigue is often experienced due to hormonal changes and the body's increased metabolic demands during pregnancy. Nausea, commonly known as morning sickness, is a well-known symptom experienced by many pregnant individuals. Increased urination is a common symptom in pregnancy due to hormonal changes leading to increased blood flow to the kidneys and increased fluid processing by the body.
Question 3 of 5
What is the purpose of genetic counseling?
Correct Answer: C
Rationale: The purpose of genetic counseling is to provide information and support to individuals and families with genetic risks. Genetic counselors aim to explain the implications of genetic testing, discuss risks and options, and offer emotional and psychological support to help individuals make informed decisions regarding their genetic health. Choice A is incorrect because genetic counseling is not focused on treatment but rather on providing information and support. Choice B is incorrect as genetic counselors do not primarily diagnose genetic diseases in newborns but rather provide guidance and support based on existing diagnoses. Choice D is not the purpose of genetic counseling; genetic counselors do not collect DNA samples for research purposes but instead focus on assisting individuals and families in understanding and managing their genetic risks.
Question 4 of 5
Which of the following substances can donate a hydroxide ion (OH-) in solution?
Correct Answer: B
Rationale: The correct answer is B: Base. A base is a substance that can donate hydroxide ions (OH-) in solution. Bases increase the concentration of hydroxide ions by either accepting protons (H+) or donating hydroxide ions. Salts are ionic compounds made of cations and anions, which do not directly donate hydroxide ions. Neutral compounds do not significantly affect the concentration of hydroxide ions. Dehydrating agents are substances that remove water molecules from other compounds, unrelated to donating hydroxide ions.
Question 5 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.
