TEAS version 7 quizlet science Questions

Question 1 of 5

Which element is used in fertilizers due to its role in plant cell division and growth?

Correct Answer: B

Rationale: Phosphorus is the correct answer. It is used in fertilizers due to its essential role in plant cell division and growth. Phosphorus is a key component of nucleic acids, such as DNA and RNA, which are essential for cell division and growth in plants. Potassium (Choice A) is important for overall plant health and functions like enzyme activation, but it is not specifically known for its role in cell division and growth. Calcium (Choice C) is crucial for cell wall structure and stability but not primarily for cell division. Magnesium (Choice D) is essential for chlorophyll production and photosynthesis, but it is not directly linked to plant cell division and growth.

Question 2 of 5

Which hormone stimulates the release of pancreatic enzymes and bile?

Correct Answer: C

Rationale: Cholecystokinin (CCK) is the correct answer. It is the hormone that stimulates the release of pancreatic enzymes and bile. CCK is released by the small intestine in response to the presence of fats and proteins in the duodenum, triggering the release of digestive enzymes and bile to aid in the digestion of fats and proteins. Gastrin (Choice A) primarily stimulates gastric acid secretion, not the release of pancreatic enzymes and bile. Insulin (Choice B) regulates blood sugar levels by promoting glucose uptake. Glucagon (Choice D) raises blood glucose levels by stimulating the breakdown of glycogen in the liver.

Question 3 of 5

What is the structural and functional unit of the kidney responsible for filtering blood?

Correct Answer: A

Rationale: The nephron is the correct answer. It is the structural and functional unit of the kidney responsible for filtering blood. The nephron consists of a renal corpuscle (glomerulus and Bowman's capsule) and a renal tubule. Within the nephron, blood is filtered to form urine, which is then carried to the ureter for excretion from the body. Choices B, C, and D are incorrect because the ureter, urethra, and bladder are not involved in the filtration of blood in the kidney. Instead, they are parts of the urinary system responsible for transporting and storing urine.

Question 4 of 5

Which of the following epithelial tissues lines the stratified squamous epithelium of the esophagus, providing a protective barrier against abrasion from food passage?

Correct Answer: B

Rationale: The correct answer is stratified squamous epithelium. This type of epithelium is found in areas subjected to mechanical and chemical stresses, such as the lining of the esophagus. The multiple layers of cells provide protection against abrasion from the passage of food. Simple squamous epithelium (choice A) is a single layer of flat cells and is not well-suited for protection against abrasion as it lacks the multiple layers. Simple cuboidal epithelium (choice C) is found in areas where secretion and absorption occur, such as kidney tubules, and is not typically found in the esophagus where protection against abrasion is necessary. Stratified cuboidal epithelium (choice D) is rare in the body and is not a characteristic tissue type of the esophagus, which requires stratified squamous epithelium for its protective function.

Question 5 of 5

During micturition, the process involves a combination of:

Correct Answer: D

Rationale: During micturition, which is the process of urination, both voluntary and involuntary muscle contractions are involved. Voluntary muscle contractions include the relaxation of the external urethral sphincter, allowing the release of urine, while involuntary muscle contractions involve the detrusor muscle in the bladder contracting to expel urine. Choices A, B, and C are incorrect because micturition is not solely dependent on gravity, voluntary muscle contractions, or involuntary muscle contractions alone. The correct answer is D as both types of muscle contractions are necessary for the complete process of urination.
