TEAS Test 7 science quizlet

1. What is the muscular sac in the female body that nourishes and protects a developing fetus during pregnancy?

Correct answer: C

Rationale: The correct answer is the uterus. The uterus is a muscular organ in the female body where a developing fetus is nourished and protected during pregnancy. It is the site where a fertilized egg implants and grows into a fetus. The ovaries produce eggs, the fallopian tubes transport the egg to the uterus for potential fertilization, and the vagina serves as the birth canal and the passage for menstrual blood to exit the body. Therefore, the uterus plays a crucial role in pregnancy by providing a nurturing environment for the developing fetus.

2. What is the function of ribosomal RNA (rRNA)?

Correct answer: C

Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes. Ribosomes are the cellular organelles responsible for protein synthesis and consist of both protein and rRNA components. The primary function of rRNA is to provide the structural support necessary for ribosomes to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during translation, where genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, rRNA's main role is in contributing to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis. Choices A, B, and D are incorrect because rRNA does not carry amino acids to the ribosomes (tRNA does this), read the genetic code (this is the role of ribosomes and tRNA), or control the rate of protein synthesis (this is regulated by various factors but not directly by rRNA).

3. Which of the following correctly describes mitosis?

Correct answer: B

Rationale: The correct answer is B. Mitosis occurs in somatic cells where a single cell divides to produce two identical daughter cells. Germ cells undergo meiosis, not mitosis. Choice C is incorrect as mitosis results in the preservation of the same chromosome number in daughter cells. Choice D is inaccurate as mitosis produces genetically identical cells, not genetically different ones.

4. Where does bile, a substance that aids in digesting fats, originate from?

Correct answer: C

Rationale: Bile is produced by the liver to aid in the digestion and absorption of fats. The liver produces bile, which is then stored and concentrated in the gallbladder before being released into the small intestine to facilitate fat digestion. The stomach (option A) is responsible for the initial digestion of food through gastric juices but does not produce bile. The pancreas (option B) secretes digestive enzymes like lipase to further break down fats in the small intestine but does not produce bile. The gallbladder (option D) stores and concentrates bile but does not produce it.

5. How should the following sentence be correctly punctuated: 'She asked me if I wanted to go to the movies with her'?

Correct answer: D

Rationale: The correct answer is D because it uses a question mark within the quoted material as it is a direct question. In this case, the sentence is a reported question, so it does not need additional punctuation within the reported speech. Choice A is incorrect as it incorrectly adds a comma before 'if.' Choice B is incorrect because a colon is not appropriate before 'if' in this context. Choice C is incorrect as it adds an unnecessary comma after 'wanted.'
